Data Collection Practices: What Information Are They Gathering?


Data Collection Practices: What Information Are They Gathering?


So, ya wanna know if you can trust your ISP, huh? IT services in sydney . Well, lets talk about what these companies are actually collecting. Its not just, like, (oh my gosh) your name and address, yknow? Theyre diving way deeper than that.


First off, they're looking at your browsing history. Every website, every search, every cat video you watch. Its all logged. They arent completely ignoring your incognito mode, though! Your ISP sees the destination, even if they dont know every single thing you did there. Then theres your location data.

  1. FTTP internet providers with unlimited data
  2. VoIP services with 24/7 support
  3. family-friendly internet packages
They wanna know where you are, and when! It is not good!


Bandwidth usage is another biggie. They track how much data youre uploading and downloading. This helps em manage their network, sure, but it also gives them insight into what youre doing online. Are you streaming a lot? Downloading large files? They can see all that.


And lets not forget about your communication data. This includes stuff like email traffic (though usually just metadata, not the content), VoIP calls, and even the websites you use for messaging. Theyre not spying on your conversations (hopefully!), but they are tracking the who, when, and where.


The truth is, your ISP knows a lot about you! Its a little creepy, aint it? You should really consider using a VPN, I tell you!

Transparency (or Lack Thereof) in Pricing and Policies


When it comes to trusting your Internet Service Provider (ISP), one of the biggest concerns is transparency (or lack thereof) in their pricing and policies. Let's face it, most of us have been there-signed up for a plan that seems too good to be true, only to find hidden fees lurking in the fine print. It's frustrating! You think you're getting a great deal, but then you get hit with unexpected charges that just don't make sense.


The truth is, many ISPs don't really make it easy for customers to understand what they're paying for. They often advertise low prices to lure you in, but then there's a whole list of add-ons that might not be clear at first. For instance, there might be installation fees, equipment rentals, or even data caps that can lead to overage charges. You might not notice these until you get your first bill, and by then it's too late to back out.


Moreover, policies regarding throttling or data management can be super vague. ISPs might say they prioritize certain types of traffic, but what does that even mean? It's like they're speaking in riddles! Customers often end up confused about how their internet speed might be affected during peak hours, leaving them unsure of whether they're actually getting what they paid for.


And let's not even get started on customer service. When you try to get clarity on these issues, you might find yourself stuck on hold for ages, or worse-talking to a rep who doesn't really know the ins and outs of the policies. It can feel like you're navigating a maze with no exit in sight.


In conclusion, if you're thinking about trusting your ISP, it's crucial to dig deeper into their pricing and policies. Don't just take their word for it; read the fine print and ask questions! Transparency is key, and without it, you might just find yourself in a situation where you feel cheated. Remember, it's your hard-earned money at stake, and you deserve to know exactly what you're paying for!

Security Vulnerabilities: Are You at Risk?


Security vulnerabilities! Are you at risk? When it comes to trusting your internet service provider (ISP), the answer isnt always straightforward. You know, theyre supposed to keep your data safe, but what if theyre not as reliable as they seem? Its a bit of a gamble, really.


Think about it, your ISP has access to a lot of your personal info. They know where you browse, what you watch, even when youre online. Now, imagine if they got hacked or if they werent following best security practices. Your private data could be up for grabs!


And dont even get me started on the whole privacy policy thing. Its like trying to read a legal document in a foreign language. You think you understand, but theres always that nagging doubt. Do they really need all that information? Do they promise not to sell it? Its hard to say for sure.


Then theres the issue of speed throttling. Some ISPs slow down your connection when you use certain services, which isnt just annoying but also raises questions about their motives. Are they just being greedy or is there more to it? You cant help but wonder if theyre keeping an eye on everything you do online.


The thing is, you cant avoid using the internet these days. Its become a necessity. So, while you might not be able to switch ISPs or use a VPN all the time, you can still take steps to protect yourself. Regularly updating your software, using strong passwords, and being cautious about the information you share online can make a big difference.


But at the end of the day, can you really trust your ISP? Its a tough question, and one that doesnt have a simple answer. Maybe its time to do a bit more digging and find out exactly whats going on behind the scenes!

Net Neutrality and ISP Control


Net neutrality is a hot topic these days, especially when we talk about trust in our Internet Service Providers (ISPs). So, what's the deal with it? Well, net neutrality is the principle that ISPs should treat all data on the internet equally, without discriminating or charging differently by user, content, or website. Sounds fair, right? But here's the catch: without proper regulations, ISPs could potentially control what we see online!


Imagine this scenario: you're trying to access a website, but your ISP has decided to slow it down because they don't like the competition it poses to their own services. Yikes! That could happen if net neutrality isn't enforced. People often think that their ISPs have their best interests at heart, but can we really trust them? It's hard to say.


Some folks argue that ISPs need to manage their networks and prioritize certain types of data to ensure a smooth experience. But others point out that this could lead to a slippery slope where only the highest bidders get the best service. It's frustrating, isn't it? Why should the internet be a place where money dictates access?


In a world where we rely on the internet for everything from work to socializing, having an ISP that can control what we see and how we experience it is a serious concern. You wouldn't want a gatekeeper deciding what information you can access. So, while some may believe they can trust their ISP, the reality is that without net neutrality, they might not have any choice in what they can see!


To sum it up, net neutrality is crucial for a free and open internet. It's not just about keeping things fair; it's about ensuring that everyone has access to the same opportunities online. If we're not careful, the dream of a truly open internet could slip away, leaving us at the mercy of our ISPs. So, think twice before you assume everything is hunky-dory with your internet provider!

Customer Service Nightmares: A Common Complaint


Customer Service Nightmares: A Common Complaint


So, youre thinking bout whether you can really trust your internet service provider (ISP), huh? Well, lets be real, it aint always sunshine and rainbows. A big ol problem (honestly, a huge one) is the customer service (or lack thereof). I mean, have you ever tried calling your ISP with an issue? Brace yourself!


Customer service nightmares? Oh boy, theyre, like, a thing. Youre stuck on hold forever, listening to that awful music, then you finally get someone who... well, they dont seem to understand your problem, or they tell you to do something youve already tried! Its infuriating! (And lets not even begin to talk about the language barriers sometimes, eh?).


Its not uncommon to hear tales of missed appointments, technicians who simply dont show up (grrr!), and bills that are, shall we say, creative in their overcharging. Theres no denying it; dealing with ISP customer service can feel like pulling teeth, and youre the dentist!


You cant say that all ISPs are bad, of course. Some folks have decent experiences. But the sheer volume of complaints regarding atrocious customer support does raise a red flag. It makes you question whether these companies truly value their customers or just see them as a number. And thats a pretty valid concern when were talking about something as essential as internet access, isnt it? So, yeah, think carefully before you commit!

Alternatives to Your Current ISP: Exploring Your Options


Okay, so, youre wondering if you can really trust your internet service provider (ISP), huh? I get it. Theyre like, a necessary evil, arent they? But maybe, just maybe, you dont have to be completely at their mercy. Lets talk about alternatives, because, well, options are good!


First off, dont just blindly accept what youre getting. Are you, like, actually getting the speeds they promised? Run some speed tests. See if theyre throttling you, or messing with your data. It's, you know, your right (or should be!) to know.


Now, what can you do if youre not feeling the love? Well, theres always the possibility of a different ISP. I know, I know, it sounds obvious. But sometimes we just stick with what we know, even if its terrible. Check out other providers in your area. Maybe a smaller, local company offers better service or a better price, and lets be honest, aint no one got money to throw away.


Another avenue is exploring satellite internet. Sure, latency can be an issue (especially if youre a hardcore gamer), but for some rural areas, it might be the only game in town. And hey, things are getting better, right?


Wireless ISPs (WISPs) are another possibility. They use radio waves to beam internet to your home. Again, location matters, but it's worth checking out if its available near you. It's a bit of a niche option, but hey, you never know!


And, of course, there's always the dream (the pipe dream?) of community-owned networks. These are usually built and maintained by local residents, and can offer great service and lower prices. However, these are not typically available.


Do not think that you have no options. It may not always be easy, but doing your homework and exploring alternatives could save you money, get you faster speeds, and maybe, just maybe, make you feel a little less like youre being taken advantage of. Yikes!

Steps You Can Take to Protect Your Privacy


Okay, so youre wondering about your ISP and, like, if you can really trust em, right? Well, its complicated. They have access to a ton of your data, which is kinda scary. But dont freak out! There are definitely steps you can take to, ya know, make things a little safer.


First off, consider a VPN (Virtual Private Network). Its like a secret tunnel for your internet traffic. It encrypts your data, making it harder for your ISP to see what youre up to.

Can You Trust Your Internet Service Provider? Herers the Truth - internet services with mobile app management in Hobart

  1. telecom infrastructure providers
  2. bulk internet deals for residential buildings
  3. data protection compliant internet plans
It aint perfect, but its a solid first line of defense.


Next, use HTTPS everywhere! Most websites do this automatically now, but always double-check for that little padlock icon in your browser bar. That means the connection between you and the site is encrypted. No padlock? Be cautious, and maybe dont enter sensitive info.


Also, think about your DNS settings. Your ISP probably uses their own DNS servers, which can track your browsing. Switching to a privacy-focused DNS provider, like Cloudflare or Google Public DNS, can help. It isnt a cure-all, but its another layer!


And hey, be smart about the information you share online. I mean, really. Do you need to share that photo of your cat wearing a tiny hat? (Okay, maybe you do, but think about it!). The less personal info out there, the better. Its not like you want to give anyone ammunition!


Finally, read the fine print. Yeah, I know, nobody likes doing that, but your ISPs privacy policy tells you exactly what theyre collecting and what theyre doing with it. Its boring, but important.


Look, you cant totally eliminate the risk. Its just not possible. But by taking these steps, you can definitely improve your privacy and make it harder for your ISP (or anyone else) to snoop on you. Good luck!

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]

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]

[edit]

 

European Strategic Programme on Research in Information Technology (ESPRIT) was a series of integrated programmes of information technology research and development projects and industrial technology transfer measures. It was a European Union initiative managed by the Directorate General for Industry (DG III) of the European Commission.

Programmes

[edit]

Five ESPRIT programmes (ESPRIT 0 to ESPRIT 4) ran consecutively from 1983 to 1998. ESPRIT 4 was succeeded by the Information Society Technologies (IST) programme in 1999.

Projects

[edit]

Some of the projects and products supported by ESPRIT were:

  • BBC Domesday Project, a partnership between Acorn Computers Ltd, Philips, Logica and the BBC with some funding from the European Commission's ESPRIT programme, to mark the 900th anniversary of the original Domesday Book, an 11th-century census of England. It is frequently cited as an example of digital obsolescence on account of the physical medium used for data storage.
  • CGAL, the Computational Geometry Algorithms Library (CGAL) is a software library that aims to provide easy access to efficient and reliable algorithms in computational geometry. While primarily written in C++, Python bindings are also available. The original funding for the project came from the ESPRIT project.
  • Eurocoop & Eurocode: ESPRIT III projects to develop systems for supporting distributed collaborative working.
  • Open Document Architecture, a free and open international standard document file format maintained by the ITU-T to replace all proprietary document file formats. In 1985 ESPRIT financed a pilot implementation of the ODA concept, involving, among others, Bull corporation, Olivetti, ICL and Siemens AG.
  • Paradise: A sub-project of the ESPRIT I project, COSINE[1] which established a pan-European computer-based network infrastructure that enabled research workers to communicate with each other using OSI. Paradise implemented a distributed X.500 directory across the academic community.
  • Password: Part of the ESPRIT III VALUE project,[2] developed secure applications based on the X.509 standard for use in the academic community.
  • ProCoS I Project (1989–1991), ProCoS II Project (1992–1995), and ProCoS-WG Working Group (1994–1997) on Provably Correct Systems, under ESPRIT II.[3]
  • REDO Project (1989–1992) on software maintenance, under ESPRIT II.[4]
  • RAISE, Rigorous Approach to Industrial Software Engineering, was developed as part of the European ESPRIT II LaCoS project in the 1990s, led by Dines Bjørner.
  • REMORA methodology is an event-driven approach for designing information systems, developed by Colette Rolland. This methodology integrates behavioral and temporal aspects with concepts for modelling the structural aspects of an information system. In the ESPRIT I project TODOS, which has led to the development of an integrated environment for the design of office information systems (OISs),
  • SAMPA: The Speech Assessment Methods Phonetic Alphabet (SAMPA) is a computer-readable phonetic script originally developed in the late 1980s.
  • SCOPES: The Systematic Concurrent design of Products, Equipments and Control Systems project was a 3-year project launched in July, 1992, with the aim of specifying integrated computer-aided (CAD) tools for design and control of flexible assembly lines.
  • SIP (Advanced Algorithms and Architectures for Speech and Image Processing), a partnership between Thomson-CSF, AEG, CSELT and ENSPS (ESPRIT P26), to develop the algorithmic and architectural techniques required for recognizing and understanding spoken or visual signals and to demonstrate these techniques in suitable applications.[5]
  • StatLog: "ESPRIT project 5170. Comparative testing and evaluation of statistical and logical learning algorithms on large-scale applications to classification, prediction and control"[6]
  • SUNDIAL (Speech UNderstanding DIALgue)[7] started in September 1988 with Logica Ltd. as prime contractor, together with Erlangen University, CSELT, Daimler-Benz, Capgemini, Politecnico di Torino. Followed the Esprit P.26 to implement and evaluate dialogue systems to be used in telephone industry.[8] The final results were 4 prototypes in 4 languages, involving speech and understanding technologies, and some criteria for evaluation were also reported.[9]
  • ISO 14649 (1999 onward): A standard for STEP-NC for CNC control developed by ESPRIT and Intelligent Manufacturing System.[10]
  • Transputers: "ESPRIT Project P1085" to develop a high performance multi-processor computer and a package of software applications to demonstrate its performance.[11]
  • Web for Schools, an ESPRIT IV project that introduced the World Wide Web in secondary schools in Europe. Teachers created more than 70 international collaborative educational projects that resulted in an exponential growth of teacher communities and educational activities using the World Wide Web
  • AGENT: A project led by IGN-France aiming at developing an operational automated map generalisation software based on multi-agent system paradigm.
