Question

first generation computer ​

Answer 1

Answer:

• These were very large computers
• For giving some input punched cards must be used
• They used vacuum tubes and they were getting so much heated that they needed to be changed regularly
• The output speed of the computers were very slow
• They were used from 1940 to 1946 until second generation computers came
• E.g. ENIAC

Answer:

First Generation Computers

The period of first generation was from 1946-1959. The computers of first generation used  vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing  Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse  frequently. Therefore, they were very expensive and only large organizations were able to  afford it.

In this generation, mainly batch processing operating system was used. Punch cards, paper  tape, and magnetic tape was used as input and output devices. The computers in this generation  used machine code as the programming language.

The main features of the first generation are:

• Vacuum tube technology

• Unreliable

• Supported machine language only

• Very costly

• Generates lot of heat

• Slow input and output devices

• Huge size

• Need of AC

• Non-portable

• Consumes lot of electricity

Some computers of this generation were:

• ENIAC

• EDVAC

• UNIVAC

• IBM-701

• IBM-750
