ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters.

The Cambridge Ring was an experimental local area network architecture developed at the Computer Laboratory, University of Cambridge starting in 1974 and continuing into the 1980s. It was a ring network with a theoretical limit of 255 nodes, around which cycled a fixed number of packets. Free packets would be "loaded" with data by a machine wishing to send, marked as received by the destination machine, and "unloaded" on return to the sender; thus in principle, there could be as many simultaneous senders as packets. The network ran over twin twisted-pair cabling.

Compunet was a United Kingdom based interactive service provider, catering primarily for the Commodore 64 but later for the Commodore Amiga and Atari ST. It was also known by its users as CNet.

Samuel Fedida, OBE was an Egyptian-born British telecommunication engineer responsible at Prestel for the development of Viewdata.

The Ferranti Market Research Terminal (MRT) was, arguably, the world’s first application-specific handheld computer. It was designed specifically for the market research sector as a means to augment the regular clipboard schemes that, at the time, were common-place, in social and market research. Despite having an appearance of a calculator built into a clipboard, the reality was that the unit contained a sophisticated form of programmable data-logger that, in response to an interviewer reading questions to the interviewee, had answers digitally recorded via pressing appropriate keys on the unit. The unit contained a bespoke operating system to support field based market research. The Ferranti Market Research Terminal (MRT) is also of historical significance to the computing industry since it marked the last original computer design from Ferranti, a long established business that had risen to fame through a collaboration Manchester University to produce the "Mark 1", the world’s first commercial computer and later with Cambridge University producing the "Atlas" and "Titan" computers which, at their peak, held around 25% of the computing market.

Tom Kilburn was an English mathematician and computer scientist. Over the course of a productive 30-year career, he was involved in the development of five computers of great historical significance. With Freddie Williams he worked on the Williams–Kilburn tube and the world's first electronic stored-program computer, the Manchester Baby, while working at the University of Manchester. His work propelled Manchester and Britain into the forefront of the emerging field of computer science.

Micro Men, working title Syntax Era is a 2009 one-off BBC drama television programme set in the late 1970s and the early-mid 1980s, about the rise of the British home computer market.

Miranda is a lazy, purely functional programming language designed by David Turner as a successor to his earlier programming languages SASL and KRC, using some concepts from ML and Hope. It was produced by Research Software Ltd. of England and was the first purely functional language to be commercially supported.

The Nimrod, built in the United Kingdom by Ferranti for the 1951 Festival of Britain, was an early computer custom-built to play Nim, inspired by the earlier Nimatron. The twelve-by-nine-by-five-foot (3.7-by-2.7-by-1.5-metre) computer, designed by John Makepeace Bennett and built by engineer Raymond Stuart-Williams, allowed exhibition attendees to play a game of Nim against an artificial intelligence. The player pressed buttons on a raised panel corresponding with lights on the machine to select their moves, and the Nimrod moved afterward, with its calculations represented by more lights. The speed of the Nimrod's calculations could be reduced to allow the presenter to demonstrate exactly what the computer was doing, with more lights showing the state of the calculations. The Nimrod was intended to demonstrate Ferranti's computer design and programming skills rather than to entertain, though Festival attendees were more interested in playing the game than the logic behind it. After its initial exhibition in May, the Nimrod was shown for three weeks in October 1951 at the Berlin Industrial Show before being dismantled.

The NPL network or NPL Data Communications Network was a local area computer network operated by a team from the National Physical Laboratory in London that pioneered the concept of packet switching.

A Premium Bond is a lottery bond issued by the United Kingdom government since 1956. At present it is issued by the government's National Savings and Investments agency.

Hugh McGregor Ross was an early pioneer in the history of British computing. He was employed by Ferranti from the mid-1960s, where he worked on the Pegasus thermionic valve computer. He was involved in the standardization of ASCII and ISO 646 and worked closely with Bob Bemer. ASCII was first known in Europe as the Bemer-Ross Code. He was also one of the four main designers of ISO 6937, with Peter Fenwick, Bernard Marti and Loek Zeckendorf. He was one of the principal architects of the Universal Character Set ISO/IEC 10646 when it was first conceived.

Christopher S. Strachey was a British computer scientist. He was one of the founders of denotational semantics, and a pioneer in programming language design and computer time-sharing. He was a member of the Strachey family, prominent in government, arts, administration, and academia.

Alan Mathison Turing was an English mathematician, computer scientist, logician, cryptanalyst, philosopher, and theoretical biologist. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence. Despite these accomplishments, he was never fully recognised in his home country during his lifetime due to the prevalence of homophobia at the time and because much of his work was covered by the Official Secrets Act.

William Thomas Tutte OC FRS FRSC was a British-born Canadian codebreaker and mathematician. During the Second World War, he made a brilliant and fundamental advance in cryptanalysis of the Lorenz cipher, a major Nazi German cipher system which was used for top-secret communications within the Wehrmacht High Command. The high-level, strategic nature of the intelligence obtained from Tutte's crucial breakthrough, in the bulk decrypting of Lorenz-enciphered messages specifically, contributed greatly, and perhaps even decisively, to the defeat of Nazi Germany. He also had a number of significant mathematical accomplishments, including foundation work in the fields of graph theory and matroid theory.

Viewdata is a Videotex implementation. It is a type of information retrieval service in which a subscriber can access a remote database via a common carrier channel, request data and receive requested data on a video display over a separate channel. Samuel Fedida, who had the idea for Viewdata in 1968, was credited as inventor of the system. The first prototype became operational in 1974. The access, request and reception are usually via common carrier broadcast channels. This is in contrast with teletext.

The Web Science Trust (WST) is a UK Charitable Trust with the aim of supporting the global development of Web science. It was originally started in 2006 as a joint effort between MIT and University of Southampton to formalise the social and technical aspects of the World Wide Web. The Trust coordinates a set of international "WSTNet Laboratories" that include academic research groups in the emerging area of Web science.
