Government Secure Intranet
Government Secure Intranet (GSi) was a United Kingdom government wide area network, whose main purpose was to enable connected organisations to communicate electronically and securely at low protective marking levels. It was known for the '.gsi.gov.uk' family of domains for government email. Migration away from these domains began in 2019 and will be completed in 2023. History Use Many UK government organisations used the GSi to transfer files on a peer-to-peer (P2P) basis between similarly accredited networks. The network itself was open within the context of its accreditation – it imposed no restrictions on traffic types carried across the network, restrictions and policy control were left to the connecting departments. Email traffic in and out of the network was filtered by an external provider. Origin The concept of GSi was defined by the Cabinet Office, and was turned into practical reality by the Internet Special Products group of Cable & Wireless (then known as ...

EGIF
An e-GIF, or eGovernment Interoperability Framework, is a scheme for ensuring the inter-operation of computer-based systems. It is intended to resolve and prevent (or at least minimise) problems arising from incompatible content of different computer systems. An e-GIF may aim to facilitate government processes at local, national or international levels. International implementations About 30 countries and international bodies are known to have implemented some form of e-GIF, most, but not all, using the "e-GIF" acronym. Within the EU many of these were supported by the European Interoperability Framework (EIF) of the IDABC. These included Denmark, Greece, the United Kingdom and the ''Reach'' "Public Services Broker" in Ireland. In Africa COMESA and Ghana provide examples of similar initiatives, whilst Bhutan and Thailand are examples from Asia. New Zealand and Australia, similarly, implemented their own frameworks. In the United States the National Information Exchange Model ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Services Network
The Public Services Network (PSN) is a UK government's high-performance network, which helps public sector organisations work together, reduce duplication and share resources. It unified the provision of network infrastructure across the United Kingdom public sector into an interconnected "network of networks" to increase efficiency and reduce overall public expenditure. It is now a legacy network and public sector organisations are being migrated to using services on the public internet. Origins The Public Services Network (PSN) was launched officially as part of the Transformational Government Strategy commencing in 2005, under the original name of the ''Public Sector Network.'' Prior to this, some parts of local government had already successfully implemented the concept. The Hampshire Public Services Network (HPSN) was the first PSN, launched in 1999, followed closely by Kent County Councils partnerships with the KPSN. The HPSN, encompassing all of the borough, district and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energis
Energis Communications Limited, briefly Telecom Electric, or more usually just Energis, was a 'technology driven communications company' based in the United Kingdom and Ireland.

Government Communications Headquarters
Government Communications Headquarters, commonly known as GCHQ, is an intelligence and security organisation responsible for providing signals intelligence (SIGINT) and information assurance (IA) to the government and armed forces of the United Kingdom. Primarily based at "The Doughnut" in the suburbs of Cheltenham, GCHQ is the responsibility of the country's Secretary of State for Foreign and Commonwealth Affairs (Foreign Secretary), but it is not a part of the Foreign Office and its Director ranks as a Permanent Secretary. GCHQ was originally established after the First World War as the Government Code and Cypher School (GC&CS) and was known under that name until 1946. During the Second World War it was located at Bletchley Park, where it was responsible for breaking the German Enigma codes. There are two main components of the GCHQ, the Composite Signals Organisation (CSO), which is responsible for gathering information, and the National Cyber Security Centre (NCSC), ...

Return On Investment
Return on investment (ROI) or return on costs (ROC) is a ratio between net income (over a period) and investment (costs resulting from an investment of some resources at a point in time). A high ROI means the investment's gains compare favourably to its cost. As a performance measure, ROI is used to evaluate the efficiency of an investment or to compare the efficiencies of several different investments.Return On Investment – ROI , Investopedia as accessed 8 January 2013 In economic terms, it is one way of relating profits to capital invested.

SMTP
The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 587 or 465 per . For retrieving messages, IMAP (which replaced the older POP3) is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync. SMTP's origins began in 1980, building on concepts implemented on the ARPANET since 1971. It has been updated, modified and extended multiple times. The protocol version in common use today has extensible structure with various extensions for authentication, encryption, binary data transfer, and internationalized email addresses. SMTP servers commonly use the Transmission Control Protocol on port number 25 (for plaintext) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Protocol
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 do ...

Wide Area Network
A wide area network (WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and suppliers from various locations around the world. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN. Design options The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks. This distinction stems from the fact that common local area network (LAN) technologies operating at lower layers of the O ...

Central Computer And Telecommunications Agency
The Central Computer and Telecommunications Agency (CCTA) was a UK government agency providing computer and telecoms support to government departments. History Formation In 1957, the UK government formed the Technical Support Unit (TSU) of HM Treasury to evaluate and advise on computers, initially based around engineers from the telecommunications service. As this unit evolved, it morphed into the Central Computer and Telecommunications Agency, which also had responsibilities as a central procurement body for government technological equipment. CCTA's work during the 1970s, 1980s and 1990s was primarily to (a) develop central government IT professionalism, (b) create a body of knowledge and experience in the successful development and implementation of IS/IT within UK central government (c) to brief Government Ministers on the opportunities for use of IS/IT to support policy initiatives (e.g. "Citizen's Charter" / "e-government") and (d) to encourage and assist UK private ...

Mercury Communications
Mercury Communications was a national telephone company in the United Kingdom, formed in 1981 as a subsidiary of Cable & Wireless, to challenge the then-monopoly of British Telecom (BT). Although it proved only moderately successful at challenging BT's dominance, it led the way for new communication companies to attempt the same. In 1997, Mercury ceased to exist as a brand after its amalgamation into the operations of Cable & Wireless. History Background: before 1981 The history of telecommunications in the United Kingdom starts in 1879, with the establishment of its first telephone exchange in London by The Telephone Company (Bells Patents) Ltd. On 10 March 1881, National Telephone Company (NTC) was formed, which later brought together smaller local telephone companies. In 1898, to break the near-monopoly held by NTC, the Postmaster General's office, which was in charge of licensing new telephone companies, issued thirteen new licences. But by 1911, five of the remaining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
