Turing is widely considered to be the father of computer science and artificial intelligence. His Turing machines — formal and simple hypothetical devices that formalised the concepts of algorithm and computation — played an important part in the creation of the modern computer

Charles Babbage English mathematician and inventor Charles Babbage is credited with having conceived the first automatic digital computer. During the mid-1830s Babbage developed plans for the Analytical Engine

Supercomputers can be as small as two computers (even laptops) or as big as a warehouse, or bigger. Supercomputers are used for large and complex mathematical computations. Mainframes are used as storage for large databases and serve a maximum number of users at a time.

A Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, as well as many monitors, projectors and high definition television sets.

It is composed of an arithmetic-logic unit (ALU) and control circuits. The ALU carries out basic arithmetic and logic operations, and the control section determines the sequence of operations, including branch instructions that transfer control from one part of a program to another

compact disc read-only memory CD-ROM, abbreviation of compact disc read-only memory, type of computer memory in the form of a compact disc that is read by optical means.
