As the people learned how to count and calculate they
started to search fast and accurate calculation device. The History
of computers starts out about 2000 years ago at the birth of Abacus.
Many mathematician and physicians had invented many other calculating
machines. In 1937 AD Howard Aiken with IBM engineers had successfully
developed the first automatic electromechanical computer, MARK-I.
The development of computers has passed many stages from the Abacus
to modern computer. The development of computer:-
ABACUS- it is used for addition, subtraction, multiplication
and division.
Napier’s Bone- Invented in 1614 by Scottish mathematician.
This could perform multiplication and
Division of numbers.
Slide Rule (1620), Pascaline(1642), Stepped
Reckoner (1694AD), Jacquard’s Loom (1801AD), Different Engine (1822AD),
Analyticv engine (1833AD), Tabulating Machine (1890AD), Harverd Mark-I
(1937AD)
Atanosoft Berry Computer(1937-1942AD), ENIAC(1943
to 1946AD), EDVAC (1946-1952AD), EDSAC (1949 A.D.), Universal Automatic
Computer (UNIVAC-I) 1951 AD- Computer for a commercial user)
