What are the Five Generations of Computers?

COMPUTER GENERATIONS

You know that the evolution of computers started in the 16th century and resulted in the form that we see today. The present-day computer, however, has also undergone rapid change ‘ during the last fifty years

COMPUTER GENERATIONS

This period, during which the evolution of computers took place, can be divided into five distinct phases known as Generations of Computers. Each phase is distinguished ‘from others on the basis of the type of switching circuits used

COMPUTER GENERATIONS

First generation computers used Thermion valves. These computers were large in size and Writing programs on them was difficult. Some of the computers of this generation were

COMPUTER GENERATIONS

ENIAC: It was the first electronic computer built in 1946 at the University of Pennsylvania, ” ‘The USA by John Eckert and John Mauchly. It was named Electronic Numerical Integrator•and Calculator (ENIAC).

COMPUTER GENERATIONS

The ENIAC was 30 and 50 feet long, weighed 30 tons, contained 18.000 vacuum tubes, 70,000 registers, 10,000 capacitors, and required 150,000 watts of electricity. Today your favorite computer is many times as powerful as ENIAC still size’s very small

COMPUTER GENERATIONS

EDVAC: It stands for Electronic Discrete Variable Automatic Computer and was developed in 1950. The concept of storing data and instructions inside the computer was introduced here.

COMPUTER GENERATIONS

This allowed much faster operation since the computer had rapid access to both data and instructions. The other advantage of storing instruction was that computers ‘could do logical decisions internally.

COMPUTER GENERATIONS

EDSAC: It stands for Electronic Delay Storage Automatic Computer and was developed by M.V. Wilkes at Cambridge University in 1949’UNIVAC-1: Ecker and Mauchly produced it in 1951 by Universal Accounting Computer ‘setup• Limitations of First Generation Computer: Followings are the major drawbacks of First generation computers.
