The greatest scientists of their era, Abu Jaffar Muhammad Ibn Musa Al-Khawarizmi (780-850), Alan Mathison Turing (1912-1954), and John Von Neuman (1903-1957) took part in the invention of computers. A mathematician and a scientist (of France) Blaise Pascal developed the first mechanical computing machine called “Paccaline” in 1642. Leibnitz invented the machine and named it the “Multiplier Wheel” to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The “MUltiplier Wheel” machine was further modified in 1971.

In 1833 Charles Babbage invented the “Analytical Engine” which was the first programmable computer. The basic units of the Analytical Engine were (I) A storage, (ii) A mill, and (iii) A control unit. Mauchly and J.P. Ekert at Moor School of Engineering in the USA gave the name to the computer as “Electronic Numerical Integrator and Calculator (ENIAC)”.
