Any computer regarding of its type is controlled by programmed instructions which give the machine a purpose and tell it what to do. The word ‘computer’ comes from the word ‘compute’ which means … Read more

Differences among various types of digital computers in respect of their size, cost and working efficiency

by

There are 4 kinds of digital computers in respect of their size, cost and working efficiency;such as (a) Microcomputer (b) Minicomputer (c) Mainframe Computer and (d) Super Computer (a) Microcomputer: ‘Mirco’ means very small. Thus as it’s name implies, microcomputers are small in size and built with microprocessors. It has CPU, ROM, RAM storage and … Read more

“Computer can be classified into 2 or 3 ways depending on it’s implementation or working principle” – Explain

by

Depending on implementation computers can be classified into 2 ways, such as, (a) General Computer (b) Special Computer (a) General Computer: General purpose computers are computers where user is not limited to a set of initially installed programs and their function. Rather than this, user can install many other programs to perform various function depending … Read more

What are the 10 characteristics of third generation of computers?

Third Generation of Computer (1965 – 1971)

Use of integrated circuits (IC) started the third generation of computer. IC reduced the size, price, use of electricity etc. IC also facilitates speed and reliability of computers. Development of IC enabled organizing the whole central processing unit in single chip. Use of monitor also started in this generation. Operating system was improved to a new level and high speed line printers were in use. Followings are some of the characteristics of third generation.

Fifth Generation of Computers

Computers from fourth generation are in use of everyday work. Fifth generation computers are from the future. Actually the computers from fifth generation are already in use under limited exposure and not available for everyone to try as the development process is still ongoing. A few of the characteristics of those fifth generation computers are already in practice or available in the fourth generation computers but those are either not complete nor available for everyone. Following are some of the characteristics of fifth generation computers.

Fourth Generation of Computers (1971 – present)

The computers that we use now-a-days are the computers from fourth generation. From this generation more use of semi-conductors in memory started. Microprocessors has been created with LSI (Large Scale Integration) and VLSI (Very Large Scale Integration). The size and price of computers has both been reduced to significant levels. Followings are some of the characteristics of computers from fourth generation.

First Generation of Computers (1951 – 1959)

Vacuum tubes were used to build computers of first generation. These computers were so large in size because of using thousands of diode, triode, transistors, capacitors etc. and also used to use a lot of electricity. These computers of first generation used to produce a lot of heat, so those were more expensive to support by setting up cooling systems. Maintenance of these huge sized computers were complex and expensive. Following are some of the characteristics of the computers of first generation.
