GQ.write note on computer system

Ans:

Computer System Computer is an electronic device that can be instructed to carry our sequences of arithmetic or logical operations .
automatically via computer programming Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.
Computers are used as control systems for a wide variety of industrial and consumer devices.
Early computers were only conceived as calculating devices.
Since ancient times, simple manual devices like the abacus helps people in doing calculations.
Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms.
More sophisticated electrical machines did specialized analog calculations in the early 20th century.
The first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers have been increasing dramatically ever since then.
The history of computer begins in the 19th century. Charles Babbage was an English mathematics professor, he designed the Analytical Engine. Design made by him was the basic framework of the today's computer. Computers can be classified into three generations.

First generation: 1937-1946-

First electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry during 1937.
It was named as the Atanasoff-Berry Computer ie ABC. Development of other computers continued until in 1946,

Second generation:

In second generation first wices like the computer was introduced in 1951 for commercial purpose. In the computer world International Business Machine which is also known as IBM made theu mark Many computer programming languages were developed and computers had memory and operating systems

Third generation :

1963 - present - Integrated circuit was developed in third generation. Due to this, computer became more dominant and more trustworthy and they are able to run many different programs at the same time.
