Essential IT Tools for Remote Collaboration


In todays world, where remote work has become almost the norm, having the right IT tools for collaboration is absolutely essential! IT services in sydney . Its not just about having a computer and internet connection; you need a whole suite of applications that make teamwork seamless, even when you're miles apart.


First off, communication is key, right? You cant just rely on email anymore. Tools like Slack or Microsoft Teams (theyre pretty popular) allow teams to chat in real-time, share files, and even video call. This way, nobody's left out of the loop, and it really helps in keeping the morale up. Plus, these platforms have integrations with other tools, so it's like having everything in one place.


Now, if you're working on projects, you definitely cant skip out on project management software. Trello and Asana are fantastic for this. They help teams stay organized and track progress. You wouldn't want to have a situation where someone's working on a task that's already been completed, right? That just leads to confusion and wasted time, and who wants that?


And let's not forget about file sharing! Google Drive or Dropbox makes it super easy to store and share documents. No more worrying about sending email attachments that might not get opened or downloaded. Everyone can access the latest version of a file whenever they need it.

It's a lifesaver!


However, it's important to remember that not all tools are created equal. Sometimes, it can be overwhelming to choose which ones to use. You dont want to end up with so many apps that your team spends more time managing them than actually working. Finding a balance is crucial!


Lastly, security can't be overlooked. With everyone working remotely, ensuring that sensitive information remains protected is vital. Using VPNs and secure collaboration tools is a must. You really can't afford to take shortcuts here.


In conclusion, leveraging IT services for remote teams is all about choosing the right tools that fit your teams needs. With the right combination of communication, project management, file sharing, and security solutions, remote collaboration can be not just effective, but also enjoyable!

Security Considerations for Remote Teams


Security, its like, totally important when your teams all over the place, right? (Duh!). When thinking bout leveraging IT services for remote teams, you cant just focus on cool tools and forget about keeping things safe. Thats a recipe for disaster, I tell ya!


Like, what happens if someones using their own, unsecured Wi-Fi at a coffee shop? Hello, data breach waiting to happen!

  2. bulk internet deals for residential buildings
  3. affordable residential VoIP services
Youve gotta make sure everyones using a VPN, no ifs, ands, or buts. And passwords? Ugh, dont even get me started. Were not usin "password123" anymore, are we? (Please say no!). Multi-factor authentication is a must. Its not negotiable.


And, like, think about devices. Are people using their own laptops? Cool, but you gotta make sure theyre patched and updated and have decent antivirus software! Its not optional; its about protecting company data, which is your data too, indirectly. Think about it! Dont neglect training either. Folks need to know how to spot phishing scams, and weird emails. Security awareness training shouldnt be a one-time thing. Its gotta be, well, a constant thing, yknow? Keeping security in mind isnt easy, but its absolutely necessary if you want your remote team to succeed without, like, a major security meltdown!

Best Practices for Managing IT Support Remotely


Managing IT support remotely can be quite a challenge, but it's not impossible! With the right best practices in place, remote teams can thrive, even when tech issues arise. First off, it's essential to have clear communication channels. You don't wanna leave your team in the dark when they encounter problems. Tools like Slack or Microsoft Teams can make it easier to report issues and get quick responses.


Another key practice is to maintain a well-organized knowledge base. When users face a problem, they shouldn't have to wait for help to find solutions. A centralized repository of FAQs, troubleshooting guides, and how-to articles can empower team members to solve minor issues on their own. This not only saves time but also boosts confidence among team members.


It's also important to prioritize regular check-ins. Just because a team is remote doesn't mean they don't need support. Scheduling weekly or bi-weekly meetings can help IT support stay in touch with the team's needs, ensuring no one feels isolated or overwhelmed (even if they're miles apart).


And let's not forget about training! Providing ongoing training sessions for your team can help them stay updated on new technologies and IT best practices.

This way, they won't feel lost when something changes, and it'll reduce the number of support tickets you receive.


Lastly, be sure to take feedback seriously. If team members are facing recurring issues, it's crucial to address those concerns and find long-term solutions instead of just putting out fires. After all, a happy team is a productive team, and that's what we all want, right? So, by implementing these best practices, managing IT support remotely can become a smoother, more efficient process.

Future Trends in IT Services for Remote Work


Okay, so check it out – future trends in IT services for remote work, right? It aint just about having a laptop and decent Wi-Fi anymore (thank goodness!). Were talking about a whole new ballgame, a paradigm shift, if you will. Think about it: remote teams are increasingly becoming the norm, and companies that dont adapt, well, theyre gonna struggle.


One big thing is hyper-personalization. We arnt just talking about generic software suites; IT services will increasingly tailor solutions to individual roles and needs. This means better tools, streamlined workflows, and (hopefully!) less frustration.


Another trend? Enhanced security, naturally. With data flying around everywhere, secure remote access and endpoint protection are absolutely crucial. We cant afford any breaches or leaks, can we? Services like zero-trust network access (ZTNA) will become increasingly important.


And lets not forget collaboration! Its not enough to just have video conferencing. We need immersive, interactive platforms that mimic the in-office experience as closely as possible. Think virtual whiteboards, shared workspaces, and even augmented reality!


AI is also set to play a bigger role.

Internet history timeline

Early research and development:

Merging the networks and creating the Internet:

Commercialization, privatization, broader access leads to the modern Internet:

Examples of Internet services:

The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referred to as TCP/IP.

The first major version of IP, Internet Protocol version 4 (IPv4), is the dominant protocol of the Internet. Its successor is Internet Protocol version 6 (IPv6), which has been in increasing deployment on the public Internet since around 2006.[1]

Function

[edit]
Encapsulation of application data carried by UDP to a link protocol frame

The Internet Protocol is responsible for addressing host interfaces, encapsulating data into datagrams (including fragmentation and reassembly) and routing datagrams from a source host interface to a destination host interface across one or more IP networks.[2] For these purposes, the Internet Protocol defines the format of packets and provides an addressing system.

Each datagram has two components: a header and a payload. The IP header includes a source IP address, a destination IP address, and other metadata needed to route and deliver the datagram. The payload is the data that is transported. This method of nesting the data payload in a packet with a header is called encapsulation.

IP addressing entails the assignment of IP addresses and associated parameters to host interfaces. The address space is divided into subnets, involving the designation of network prefixes. IP routing is performed by all hosts, as well as routers, whose main function is to transport packets across network boundaries. Routers communicate with one another via specially designed routing protocols, either interior gateway protocols or exterior gateway protocols, as needed for the topology of the network.[3]

Addressing methods

[edit]
Routing schemes
Unicast

Broadcast

Multicast

Anycast

There are four principal addressing methods in the Internet Protocol:

  • Unicast delivers a message to a single specific node using a one-to-one association between a sender and destination: each destination address uniquely identifies a single receiver endpoint.
  • Broadcast delivers a message to all nodes in the network using a one-to-all association; a single datagram (or packet) from one sender is routed to all of the possibly multiple endpoints associated with the broadcast address. The network automatically replicates datagrams as needed to reach all the recipients within the scope of the broadcast, which is generally an entire network subnet.
  • Multicast delivers a message to a group of nodes that have expressed interest in receiving the message using a one-to-many-of-many or many-to-many-of-many association; datagrams are routed simultaneously in a single transmission to many recipients. Multicast differs from broadcast in that the destination address designates a subset, not necessarily all, of the accessible nodes.
  • Anycast delivers a message to any one out of a group of nodes, typically the one nearest to the source using a one-to-one-of-many[4] association where datagrams are routed to any single member of a group of potential receivers that are all identified by the same destination address. The routing algorithm selects the single receiver from the group based on which is the nearest according to some distance or cost measure.

Version history

[edit]
A timeline for the development of the transmission control Protocol TCP and Internet Protocol IP
First Internet demonstration, linking the ARPANET, PRNET, and SATNET on November 22, 1977

In May 1974, the Institute of Electrical and Electronics Engineers (IEEE) published a paper entitled "A Protocol for Packet Network Intercommunication".[5] The paper's authors, Vint Cerf and Bob Kahn, described an internetworking protocol for sharing resources using packet switching among network nodes. A central control component of this model was the Transmission Control Program that incorporated both connection-oriented links and datagram services between hosts. The monolithic Transmission Control Program was later divided into a modular architecture consisting of the Transmission Control Protocol and User Datagram Protocol at the transport layer and the Internet Protocol at the internet layer. The model became known as the Department of Defense (DoD) Internet Model and Internet protocol suite, and informally as TCP/IP.

The following Internet Experiment Note (IEN) documents describe the evolution of the Internet Protocol into the modern version of IPv4:[6]

  • IEN 2 Comments on Internet Protocol and TCP (August 1977) describes the need to separate the TCP and Internet Protocol functionalities (which were previously combined). It proposes the first version of the IP header, using 0 for the version field.
  • IEN 26 A Proposed New Internet Header Format (February 1978) describes a version of the IP header that uses a 1-bit version field.
  • IEN 28 Draft Internetwork Protocol Description Version 2 (February 1978) describes IPv2.
  • IEN 41 Internetwork Protocol Specification Version 4 (June 1978) describes the first protocol to be called IPv4. The IP header is different from the modern IPv4 header.
  • IEN 44 Latest Header Formats (June 1978) describes another version of IPv4, also with a header different from the modern IPv4 header.
  • IEN 54 Internetwork Protocol Specification Version 4 (September 1978) is the first description of IPv4 using the header that would become standardized in 1980 as RFC 760.
  • IEN 80
  • IEN 111
  • IEN 123
  • IEN 128/RFC 760 (1980)

IP versions 1 to 3 were experimental versions, designed between 1973 and 1978.[7] Versions 2 and 3 supported variable-length addresses ranging between 1 and 16 octets (between 8 and 128 bits).[8] An early draft of version 4 supported variable-length addresses of up to 256 octets (up to 2048 bits)[9] but this was later abandoned in favor of a fixed-size 32-bit address in the final version of IPv4. This remains the dominant internetworking protocol in use in the Internet Layer; the number 4 identifies the protocol version, carried in every IP datagram. IPv4 is defined in

RFC 791 (1981).

Version number 5 was used by the Internet Stream Protocol, an experimental streaming protocol that was not adopted.[7]

The successor to IPv4 is IPv6. IPv6 was a result of several years of experimentation and dialog during which various protocol models were proposed, such as TP/IX (

RFC 1475), PIP (

RFC 1621) and TUBA (TCP and UDP with Bigger Addresses,

RFC 1347). Its most prominent difference from version 4 is the size of the addresses. While IPv4 uses 32 bits for addressing, yielding c. 4.3 billion (4.3×109) addresses, IPv6 uses 128-bit addresses providing c. 3.4×1038 addresses. Although adoption of IPv6 has been slow, as of January 2023, most countries in the world show significant adoption of IPv6,[10] with over 41% of Google's traffic being carried over IPv6 connections.[11]

The assignment of the new protocol as IPv6 was uncertain until due diligence assured that IPv6 had not been used previously.[12] Other Internet Layer protocols have been assigned version numbers,[13] such as 7 (IP/TX), 8 and 9 (historic). Notably, on April 1, 1994, the IETF published an April Fools' Day RfC about IPv9.[14] IPv9 was also used in an alternate proposed address space expansion called TUBA.[15] A 2004 Chinese proposal for an IPv9 protocol appears to be unrelated to all of these, and is not endorsed by the IETF.

IP version numbers

Reliability

[edit]

The design of the Internet protocol suite adheres to the end-to-end principle, a concept adapted from the CYCLADES project. Under the end-to-end principle, the network infrastructure is considered inherently unreliable at any single network element or transmission medium and is dynamic in terms of the availability of links and nodes. No central monitoring or performance measurement facility exists that tracks or maintains the state of the network. For the benefit of reducing network complexity, the intelligence in the network is located in the end nodes.

As a consequence of this design, the Internet Protocol only provides best-effort delivery and its service is characterized as unreliable. In network architectural parlance, it is a connectionless protocol, in contrast to connection-oriented communication. Various fault conditions may occur, such as data corruption, packet loss and duplication. Because routing is dynamic, meaning every packet is treated independently, and because the network maintains no state based on the path of prior packets, different packets may be routed to the same destination via different paths, resulting in out-of-order delivery to the receiver.

All fault conditions in the network must be detected and compensated by the participating end nodes. The upper layer protocols of the Internet protocol suite are responsible for resolving reliability issues. For example, a host may buffer network data to ensure correct ordering before the data is delivered to an application.

IPv4 provides safeguards to ensure that the header of an IP packet is error-free. A routing node discards packets that fail a header checksum test. Although the Internet Control Message Protocol (ICMP) provides notification of errors, a routing node is not required to notify either end node of errors. IPv6, by contrast, operates without header checksums, since current link layer technology is assumed to provide sufficient error detection.[25][26]

[edit]

The dynamic nature of the Internet and the diversity of its components provide no guarantee that any particular path is actually capable of, or suitable for, performing the data transmission requested. One of the technical constraints is the size of data packets possible on a given link. Facilities exist to examine the maximum transmission unit (MTU) size of the local link and Path MTU Discovery can be used for the entire intended path to the destination.[27]

The IPv4 internetworking layer automatically fragments a datagram into smaller units for transmission when the link MTU is exceeded. IP provides re-ordering of fragments received out of order.[28] An IPv6 network does not perform fragmentation in network elements, but requires end hosts and higher-layer protocols to avoid exceeding the path MTU.[29]

The Transmission Control Protocol (TCP) is an example of a protocol that adjusts its segment size to be smaller than the MTU. The User Datagram Protocol (UDP) and ICMP disregard MTU size, thereby forcing IP to fragment oversized datagrams.[30]

Security

[edit]

During the design phase of the ARPANET and the early Internet, the security aspects and needs of a public, international network were not adequately anticipated. Consequently, many Internet protocols exhibited vulnerabilities highlighted by network attacks and later security assessments. In 2008, a thorough security assessment and proposed mitigation of problems was published.[31] The IETF has been pursuing further studies.[32]

A server is a physical component to IT Infrastructure.

Information technology infrastructure is defined broadly as a set of information technology (IT) components that are the foundation of an IT service; typically physical components (computer and networking hardware and facilities), but also various software and network components.[1][2]

According to the ITIL Foundation Course Glossary, IT Infrastructure can also be termed as “All of the hardware, software, networks, facilities, etc., that are required to develop, test, deliver, monitor, control or support IT services. The term IT infrastructure includes all of the Information Technology but not the associated People, Processes and documentation.”[3]

Overview

[edit]

In IT Infrastructure, the above technological components contribute to and drive business functions. Leaders and managers within the IT field are responsible for ensuring that both the physical hardware and software networks and resources are working optimally. IT infrastructure can be looked at as the foundation of an organization's technology systems, thereby playing an integral part in driving its success.[4] All organizations who rely on technology to do their business can benefit from having a robust, interconnected IT Infrastructure. With the current speed that technology changes and the competitive nature of businesses, IT leaders have to ensure that their IT Infrastructure is designed such that changes can be made quickly and without impacting the business continuity.[5] While traditionally companies used to typically rely on physical data centers or colocation facilities to support their IT Infrastructure, cloud hosting has become more popular as it is easier to manage and scale. IT Infrastructure can be managed by the company itself or it can be outsourced to another company that has consulting expertise to develop robust infrastructures for an organization.[6] With advances in online outreach availability, it has become easier for end users to access technology. As a result, IT infrastructures have become more complex and therefore, it is harder for managers to oversee the end to end operations. In order to mitigate this issue, strong IT Infrastructures require employees with varying skill sets. The fields of IT management and IT service management rely on IT infrastructure, and the ITIL framework was developed as a set of best practices with regard to IT infrastructure. The ITIL framework assists companies with the ability to be responsive to technological market demands. Technology can often be thought of as an innovative product which can incur high production costs. However, the ITIL framework helps address these issues and allows the company to be more cost effective which helps IT managers to keep the IT Infrastructure functioning.[7]

Background

[edit]

Even though the IT infrastructure has been around for over 60 years, there have been incredible advances in technology in the past 15 years.[8]

Components of IT infrastructure

[edit]
Network switch

The primary components of an IT Infrastructure are the physical systems such as hardware, storage, any kind of routers/switches and the building itself but also networks and software .[9] In addition to these components, there is the need for “IT Infrastructure Security”. Security keeps the network and its devices safe in order to maintain the integrity within the overall infrastructure of the organization.[10]

Specifically, the first three layers are directly involved with IT Infrastructure. The physical layer serves as the fundamental layer for hardware. The second and third layers (Data Link and Network), are essential for communication to and from hardware devices. Without this, networking is not possible. Therefore, in a sense, the internet itself would not be possible.[11] It's important to emphasize that fiber optics play a crucial role in a network infrastructure. Fiber optics[12] serve as the primary means for connecting network equipment and establishing connections between buildings.

IT Infrastructure types

[edit]
Starlink

Different types of technological tasks may require a tailored approach to the infrastructure. These can be achieved through a traditional, cloud or hyper converged IT Infrastructure.[13]

Skills

[edit]

There are many functioning parts that go into the health of an IT infrastructure. In order to contribute positively to the organization, employees can acquire abilities to benefit the company. These include key technical abilities such as cloud, network, and data administration skills and soft abilities such as collaboration and communication skills.[14][15]

Future

[edit]

As data storage and management becomes more digitized, IT Infrastructure is moving towards the cloud. Infrastructure-as-a-service (IaaS) provides the ability to host on a server and is a platform for cloud computing.[16]

Information technology (IT) is a set of related areas within info and interactions modern technology (ICT), that encompass computer system systems, software program, shows languages, data and data processing, and storage space. Infotech is an application of computer science and computer design. The term is frequently utilized as a synonym for computers and local area network, but it additionally incorporates various other info distribution innovations such as tv and telephones. Numerous product and services within an economic climate are connected with information technology, consisting of computer, software application, electronic devices, semiconductors, net, telecom tools, and e-commerce. An infotech system (IT system) is normally a details system, an interactions system, or, a lot more particularly speaking, a computer system —-- consisting of all hardware, software application, and outer tools —-- operated by a limited team of IT users, and an IT job typically refers to the commissioning and application of an IT system. IT systems play an important role in assisting in effective information administration, enhancing communication networks, and supporting business procedures throughout different markets. Effective IT jobs need careful preparation and ongoing maintenance to ensure ideal functionality and positioning with organizational objectives. Although human beings have been saving, obtaining, manipulating, evaluating and interacting info because the earliest writing systems were established, the term information technology in its modern feeling first appeared in a 1958 write-up published in the Harvard Organization Testimonial; authors Harold J. Leavitt and Thomas L. Whisler commented that "the brand-new modern technology does not yet have a single well established name. We will call it information technology (IT)." Their interpretation consists of three groups: strategies for handling, the application of analytical and mathematical approaches to decision-making, and the simulation of higher-order thinking through computer programs.

Information technology (IT) is a set of related fields within information and communications technology (ICT), that encompass computer systems, software, programming languages, data and information processing, and storage. Information technology is an application of computer science and computer engineering.

The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.[1][a]

An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users, and an IT project usually refers to the commissioning and implementation of an IT system.[3] IT systems play a vital role in facilitating efficient data management, enhancing communication networks, and supporting organizational processes across various industries. Successful IT projects require meticulous planning and ongoing maintenance to ensure optimal functionality and alignment with organizational objectives.[4]

Although humans have been storing, retrieving, manipulating, analysing and communicating information since the earliest writing systems were developed,[5] the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)."[6] Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs.[6]

History

[edit]
Antikythera mechanism, considered the first mechanical analog computer, dating back to the first century BC.

Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450 – 1840), electromechanical (1840 – 1940), and electronic (1940 to present).[5]

Ideas of computer science were first mentioned before the 1950s under the Massachusetts Institute of Technology (MIT) and Harvard University, where they had discussed and began thinking of computer circuits and numerical calculations. As time went on, the field of information technology and computer science became more complex and was able to handle the processing of more data. Scholarly articles began to be published from different organizations.[7]

During the early computing, Alan Turing, J. Presper Eckert, and John Mauchly were considered some of the major pioneers of computer technology in the mid-1900s. Giving them such credit for their developments, most of their efforts were focused on designing the first digital computer. Along with that, topics such as artificial intelligence began to be brought up as Turing was beginning to question such technology of the time period.[8]

Devices have been used to aid computation for thousands of years, probably initially in the form of a tally stick.[9] The Antikythera mechanism, dating from about the beginning of the first century BC, is generally considered the earliest known mechanical analog computer, and the earliest known geared mechanism.[10] Comparable geared devices did not emerge in Europe until the 16th century, and it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed.[11]

Electronic computers, using either relays or valves, began to appear in the early 1940s. The electromechanical Zuse Z3, completed in 1941, was the world's first programmable computer, and by modern standards one of the first machines that could be considered a complete computing machine. During the Second World War, Colossus developed the first electronic digital computer to decrypt German messages. Although it was programmable, it was not general-purpose, being designed to perform only a single task. It also lacked the ability to store its program in memory; programming was carried out using plugs and switches to alter the internal wiring.[12] The first recognizably modern electronic digital stored-program computer was the Manchester Baby, which ran its first program on 21 June 1948.[13]

The development of transistors in the late 1940s at Bell Laboratories allowed a new generation of computers to be designed with greatly reduced power consumption. The first commercially available stored-program computer, the Ferranti Mark I, contained 4050 valves and had a power consumption of 25 kilowatts. By comparison, the first transistorized computer developed at the University of Manchester and operational by November 1953, consumed only 150 watts in its final version.[14]

Several other breakthroughs in semiconductor technology include the integrated circuit (IC) invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor in 1959, silicon dioxide surface passivation by Carl Frosch and Lincoln Derick in 1955,[15] the first planar silicon dioxide transistors by Frosch and Derick in 1957,[16] the MOSFET demonstration by a Bell Labs team,[17][18][19][20] the planar process by Jean Hoerni in 1959,[21][22][23] and the microprocessor invented by Ted Hoff, Federico Faggin, Masatoshi Shima, and Stanley Mazor at Intel in 1971. These important inventions led to the development of the personal computer (PC) in the 1970s, and the emergence of information and communications technology (ICT).[24]

By 1984, according to the National Westminster Bank Quarterly Review, the term information technology had been redefined as "the convergence of telecommunications and computing technology (...generally known in Britain as information technology)." We then begin to see the appearance of the term in 1990 contained within documents for the International Organization for Standardization (ISO).[25]

Innovations in technology have already revolutionized the world by the twenty-first century as people have gained access to different online services. This has changed the workforce drastically as thirty percent of U.S. workers were already in careers in this profession. 136.9 million people were personally connected to the Internet, which was equivalent to 51 million households.[26] Along with the Internet, new types of technology were also being introduced across the globe, which has improved efficiency and made things easier across the globe.

As technology revolutionized society, millions of processes could be completed in seconds. Innovations in communication were crucial as people increasingly relied on computers to communicate via telephone lines and cable networks. The introduction of the email was considered revolutionary as "companies in one part of the world could communicate by e-mail with suppliers and buyers in another part of the world...".[27]

Not only personally, computers and technology have also revolutionized the marketing industry, resulting in more buyers of their products. In 2002, Americans exceeded $28 billion in goods just over the Internet alone while e-commerce a decade later resulted in $289 billion in sales.[27] And as computers are rapidly becoming more sophisticated by the day, they are becoming more used as people are becoming more reliant on them during the twenty-first century.

 

Data processing

[edit]

Electronic data processing or business information processing can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and customer master files, booking and ticketing transactions to an airline's reservation system, billing for utility services. The modifier "electronic" or "automatic" was used with "data processing" (DP), especially c. 1960, to distinguish human clerical data processing from that done by computer.[28][29]

Storage

[edit]
Punched tapes were used in early computers to store and represent data.

Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete.[30] Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line.[31] The first random-access digital storage device was the Williams tube, which was based on a standard cathode ray tube.[32] However, the information stored in it and delay-line memory was volatile in the fact that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of non-volatile computer storage was the magnetic drum, invented in 1932[33] and used in the Ferranti Mark 1, the world's first commercially available general-purpose electronic computer.[34]

IBM introduced the first hard disk drive in 1956, as a component of their 305 RAMAC computer system.[35]: 6  Most digital data today is still stored magnetically on hard disks, or optically on media such as CD-ROMs.[36]: 4–5  Until 2002 most information was stored on analog devices, but that year digital storage capacity exceeded analog for the first time. As of 2007, almost 94% of the data stored worldwide was held digitally:[37] 52% on hard disks, 28% on optical devices, and 11% on digital magnetic tape. It has been estimated that the worldwide capacity to store information on electronic devices grew from less than 3 exabytes in 1986 to 295 exabytes in 2007,[38] doubling roughly every 3 years.[39]

Databases

[edit]

Database Management Systems (DMS) emerged in the 1960s to address the problem of storing and retrieving large amounts of data accurately and quickly. An early such system was IBM's Information Management System (IMS),[40] which is still widely deployed more than 50 years later.[41] IMS stores data hierarchically,[40] but in the 1970s Ted Codd proposed an alternative relational storage model based on set theory and predicate logic and the familiar concepts of tables, rows, and columns. In 1981, the first commercially available relational database management system (RDBMS) was released by Oracle.[42]

All DMS consist of components; they allow the data they store to be accessed simultaneously by many users while maintaining its integrity.[43] All databases are common in one point that the structure of the data they contain is defined and stored separately from the data itself, in a database schema.[40]

In the late 2000s (decade), the extensible markup language (XML) has become a popular format for data representation. Although XML data can be stored in normal file systems, it is commonly held in relational databases to take advantage of their "robust implementation verified by years of both theoretical and practical effort."[44] As an evolution of the Standard Generalized Markup Language (SGML), XML's text-based structure offers the advantage of being both machine- and human-readable.[45]

 

Transmission

[edit]

Data transmission has three aspects: transmission, propagation, and reception.[46] It can be broadly categorized as broadcasting, in which information is transmitted unidirectionally downstream, or telecommunications, with bidirectional upstream and downstream channels.[38]

XML has been increasingly employed as a means of data interchange since the early 2000s,[47] particularly for machine-oriented interactions such as those involved in web-oriented protocols such as SOAP,[45] describing "data-in-transit rather than... data-at-rest".[47]

Manipulation

[edit]

Hilbert and Lopez identify the exponential pace of technological change (a kind of Moore's law): machines' application-specific capacity to compute information per capita roughly doubled every 14 months between 1986 and 2007; the per capita capacity of the world's general-purpose computers doubled every 18 months during the same two decades; the global telecommunication capacity per capita doubled every 34 months; the world's storage capacity per capita required roughly 40 months to double (every 3 years); and per capita broadcast information has doubled every 12.3 years.[38]

Massive amounts of data are stored worldwide every day, but unless it can be analyzed and presented effectively it essentially resides in what have been called data tombs: "data archives that are seldom visited".[48] To address that issue, the field of data mining — "the process of discovering interesting patterns and knowledge from large amounts of data"[49] — emerged in the late 1980s.[50]

 

Services

[edit]

Email

[edit]

The technology and services IT provides for sending and receiving electronic messages (called "letters" or "electronic letters") over a distributed (including global) computer network. In terms of the composition of elements and the principle of operation, electronic mail practically repeats the system of regular (paper) mail, borrowing both terms (mail, letter, envelope, attachment, box, delivery, and others) and characteristic features — ease of use, message transmission delays, sufficient reliability and at the same time no guarantee of delivery. The advantages of e-mail are: easily perceived and remembered by a person addresses of the form user_name@domain_name (for example, somebody@example.com); the ability to transfer both plain text and formatted, as well as arbitrary files; independence of servers (in the general case, they address each other directly); sufficiently high reliability of message delivery; ease of use by humans and programs.

The disadvantages of e-mail include: the presence of such a phenomenon as spam (massive advertising and viral mailings); the theoretical impossibility of guaranteed delivery of a particular letter; possible delays in message delivery (up to several days); limits on the size of one message and on the total size of messages in the mailbox (personal for users).

Search system

[edit]

A search system is software and hardware complex with a web interface that provides the ability to look for information on the Internet. A search engine usually means a site that hosts the interface (front-end) of the system. The software part of a search engine is a search engine (search engine) — a set of programs that provides the functionality of a search engine and is usually a trade secret of the search engine developer company. Most search engines look for information on World Wide Web sites, but there are also systems that can look for files on FTP servers, items in online stores, and information on Usenet newsgroups. Improving search is one of the priorities of the modern Internet (see the Deep Web article about the main problems in the work of search engines).

Commercial effects

[edit]

Companies in the information technology field are often discussed as a group as the "tech sector" or the "tech industry."[51][52][53] These titles can be misleading at times and should not be mistaken for "tech companies," which are generally large scale, for-profit corporations that sell consumer technology and software. From a business perspective, information technology departments are a "cost center" the majority of the time. A cost center is a department or staff which incurs expenses, or "costs," within a company rather than generating profits or revenue streams. Modern businesses rely heavily on technology for their day-to-day operations, so the expenses delegated to cover technology that facilitates business in a more efficient manner are usually seen as "just the cost of doing business." IT departments are allocated funds by senior leadership and must attempt to achieve the desired deliverables while staying within that budget. Government and the private sector might have different funding mechanisms, but the principles are more or less the same. This is an often overlooked reason for the rapid interest in automation and artificial intelligence, but the constant pressure to do more with less is opening the door for automation to take control of at least some minor operations in large companies.

Many companies now have IT departments for managing the computers, networks, and other technical areas of their businesses. Companies have also sought to integrate IT with business outcomes and decision-making through a BizOps or business operations department.[54]

In a business context, the Information Technology Association of America has defined information technology as "the study, design, development, application, implementation, support, or management of computer-based information systems".[55][page needed] The responsibilities of those working in the field include network administration, software development and installation, and the planning and management of an organization's technology life cycle, by which hardware and software are maintained, upgraded, and replaced.

Information services

[edit]

Information services is a term somewhat loosely applied to a variety of IT-related services offered by commercial companies,[56][57][58] as well as data brokers.

Ethics

[edit]

The field of information ethics was established by mathematician Norbert Wiener in the 1940s.[60]: 9  Some of the ethical issues associated with the use of information technology include:[61]: 20–21 

  • Breaches of copyright by those downloading files stored without the permission of the copyright holders
  • Employers monitoring their employees' emails and other Internet usage
  • Unsolicited emails
  • Hackers accessing online databases
  • Web sites installing cookies or spyware to monitor a user's online activities, which may be used by data brokers

IT projects

[edit]

Research suggests that IT projects in business and public administration can easily become significant in scale. Research conducted by McKinsey in collaboration with the University of Oxford suggested that half of all large-scale IT projects (those with initial cost estimates of $15 million or more) often failed to maintain costs within their initial budgets or to complete on time.[62]

Notes

[edit]
  1. ^ On the later more broad application of the term IT, Keary comments: "In its original application 'information technology' was appropriate to describe the convergence of technologies with application in the vast field of data storage, retrieval, processing, and dissemination. This useful conceptual term has since been converted to what purports to be of great use, but without the reinforcement of definition ... the term IT lacks substance when applied to the name of any function, discipline, or position."[2]
