A Turing machine is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer. The “Turing” machine … Continue reading Turing machine
In computing, time-sharing is the sharing of a computing resource among many users by means of multiprogramming and multi-tasking. Its introduction in the 1960s, and emergence as the prominent model of computing in the 1970s, represents a major technological shift in the history of computing.
Sir Timothy John “Tim” Berners-Lee, OM, KBE, FRS, FREng, FRSA (born 8 June 1955), also known as “TimBL,” is a British computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989, and he implemented the first successful communication between a Hypertext … Continue reading Tim Berners-Lee
The surface Web (also known as the Clearnet, the visible Web or indexable Web) is that portion of the World Wide Web that is indexable by conventional search engines. The part of the Web that is not reachable this way is called the Deep Web. Search engines construct a database of the Web by using … Continue reading Surface Web
A supercomputer is a computer at the frontline of current processing capacity, particularly speed of calculation. The term “Super Computing” was first used in the New York World in 1929 to refer to large custom-built tabulators that IBM had made for Columbia University. Supercomputers were introduced in the 1960s and were designed primarily by Seymour … Continue reading Supercomputer
Charles Babbage, FRS (26 December 1791 – 18 October 1871) was an English mathematician, philosopher, inventor and mechanical engineer who originated the concept of a programmable computer. Considered a “father of the computer”, Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. Parts of his uncompleted mechanisms are on … Continue reading Charles Babbage
