1912(b)-1954(d). English mathematician, logician and philosopher who made important advancements in the field of computer theory and who contributed important logical analyses of computer processes. During WWII, Turing served in the cryptanalytic headquarters at the Government Code and Cypher School at Bletchley Park, Buckinghamshire, where he was largely responsible for breaking the German Enigma military codes. In 1936, he introduced the Universal Turing Machine, a hypothetical machine used for computability theory proofs. The Universal Turing Machine is regarded as the first digital computer.
In 1950, Turing introduced the Turing Test to prove his theory that computers eventually would be constructed that would be capable of human thought. His papers on the subject provide a foundation for modern research in artificial intelligence.
In his later years, Turing worked on the application of mathematical theory to biological forms. In 1952 he published the first part of his theoretical study of morphogenesis, the development of pattern and form in living organisms.
In an unfortunate end to his prolific career, Turing was arrested in 1952 after British authorities found out he was having a relationship with another man. Under British law, homosexuality was a crime, and it resulted in Turing losing his security clearance to continue his work at Bletchley Park. Rather than face a life in prison, Turing accepted treatment of regular estrogen injections, which were believed to neutralize libido. In 1954, Turing committed suicide by eating a cyanide-laced apple.

- All-to-all broadcast
In distributed computing, AAB or All-to-all broadcast is the process where every node broadcasts its information to all other nodes.
1. A protocol for satellite and terrestrial radio transmissions. In pure Aloha, a user can transmit at any time but risks collisions with other users’ messages. “Slotted Aloha” reduces the chance of collisions by dividing the channel into time slots and requiring that the user send only at the beginning of a time slot. Aloha […]
- Alpha Processor
A powerful RISC processor developed by Digital Equipment Corporation and used in their line of workstations and servers.
- Alt key
Short for Alternate key, the Alt key is like a second Control key. Not all computer keyboards have an Alt key, but it is standard on all PCs. You use it in the same fashion as the Control key — holding it down while you press another key. For example, an instruction to use the […]
