~ Abacus is the first mechanical computing devices developed by the Chinese between 500 to 600 B.C.E.
b) Writen the period of evolution of computer.
~The period of evolution of computer are:
1 Period of developing mechanical computing devices.
2 Period of developing electro mechanical computers.
3 Period of developing electronic computer.
c)Who invented slide rule and when?
~William Oughtred slide rule in 1620 AD .
d) what is pascaline and when was it invented?
~ Pascaline is a devices which contains eight dials, gears and toothed metal wheels which can add and subtract by the movement of wheel. It was invented in 1642 A.D. .
e) Who is known as the 'father of the modern computer and why?
~ Charles Babbage is known as the father of modern computer because he invented a machine named analytical engine which consist five functional units ( Input unit, Output units ,Memory unit, Arithemetics unit , and control unit) which resemble the architecture of today's modern computer.
f) Why is Lady August Ada Lovelace called first programmer.
~ Lady August Ada Lovelace called first programmer because she helped Charles Babbage to write programs for his analytical engine and also suggested Babbage to use binary number system for programs and data in his machine.
g) Define tabulating machine and write its use .
~ Tabulating machine is a machine used in method of card punching for storing data , which is fed into a Machine that compiled the result mechanically.
It is use to computer the US census record with very high speed.
h) Define UNIVAC-1 .
~ John William Mauchly and John Prespre Eckert invented UNIVAC -1 in 1951 A.D. . It was the first general purpose electronic digital computer for commercial users .It used magnetic tape for input and output.
