Generations of Computers

GENERATIONS OF COMPUTER

INTRODUCTION:

Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.

The history of computer development is often referred to in reference to the different generations of computing devices. Each of the five generation of computers is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. Learn about each generation and the developments that led to the current devices that we use today

FIRST GENRATION (1940-1956) VACUUM TUBES:

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.

The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951

Advantages of first generation computers:

First generation computers didn’t have any benefits other then they were could perform several tasks.

Disadvantages of first generation computers:

1. Use of vacuum tubes

2. Big & Clumsy

3. High Electricity Consumption

4. Programming in Mechanical Language

5. Larger AC were needed

6. Lot of electricity failure occurred
