.He created odd machines like “Differential Engine” and “ Analytical
Engine” whuich could calculate
correctly.

Engine, the machine was equipped with
gears and soft. Babbage has been a major contributor to the development of
computers. Charles babbage is called the
father of computer science.
DR.HOWARD AIKEN’S MARK – 1 -: Four top IBM engineers and Dr.howard aiken developed a Machine in 1944.it was the
world’s first “electrical mechanical” computer.offical name – Automatic
Sequence Controlled Calcutator. It
could do to times in 6 seconds and 1 in 12 seconds. Its Mark-1
named Howard university.
ATANASOFF – BERRY COMPUTER (A.B.C.) -: In
1945,Atanasoff and Clifford berry developed an electronic machine. ABC was
