Evolution History of computer Technology

(HISTORY OF COMPUTER)

Evolution of computer is a study of past development of computer i.e. it is meant by the gradual improvements of accuracy, speed and efficiency of computers through generations, whereas generations of computers may be defined as the development of computer in an average period of time in which old computer technology may be replaced by newer technology.

Ancient people lived on the earth for centuries without counting. Then, they started to count their ten figures. It become so difficult to live and to remember anything. These phenomena were gradually replaced by the use of stones, counting notches on sticks or marks on walls. The different generations are described below which has helped the humans for keeping records with the passing of time.

A) The Mechanical Era (Zeroth Generation)

The calculating devices of this era were made from mechanical components such as wood, metal, stone, and bone. They were mainly used for simple mathematical calculations.

B) The Electro-Mechanical Era

Computers of this era used both mechanical and electrical/electronic components.

 

C) The Electronic Computer Era

Computers of this era were built using electronic components such as vacuum tubes, transistors, integrated circuits (ICs), and VLSI technology. They became smaller, faster, and more reliable.
