What are the features of 1st generation of computer?

The main characteristics of first generation of computers (1940s-1950s)

• Main electronic component – vacuum tube.
• Main memory – magnetic drums and magnetic tapes.
• Programming language – machine language.
• Power – consume a lot of electricity and generate a lot of heat.

What are 3 differences between the 1st and 2nd generation computers?

1) The first generation computer made use of vacuum tubes as internal component, whereas transistors were used in the second generation. 5) The main memory of the first generation computer is in form of magnetic drum, while the main memory of the second generation computer is in form of RAM and ROM.

What is used in first generation of computer?

vacuum tubes
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.

What are the three features of third generation computer?

Characteristics of third generation computers include:

• Integrated circuits instead of individual transistors.
• Smaller, cheaper, more efficient and faster than second generation computers.
• High-level programming languages.
• Magnetic storage.

Which is the third generation computer?

The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry.

What is the different between first generation and second generation of computer?

in First Generation, Vacuum tubes were used as internal components. in Second Generation Transistors were used as internal component. in SG The sizes of computer were smaller than first generation & were called as mini computer.

What are the three generations of computer?

This photo illustrates what were commonly known as the three generations:

• First generation: Vacuum tubes (left). Mid 1940s, beginning with ENIAC.
• Second generation: Transistors (right). 1956.
• Third generation: Integrated circuits (foreground), silicon chips contain multiple transistors. 1964.

What’s the first generation?

First generation can refer to a person born in the U.S. to immigrant parents or a naturalized American citizen. Both types of people are considered to be U.S. citizens.

What are the first five generation of computer?

Computer – Generations

What are the main features of fifth generation computer?

ULSI technology.

What is the third generation?

Definition of third-generation 1 : being a member of the third generation of a family to be born in the U.S. a third-generation American. 2 : being a member of the second generation of a family to be born in the U.S.

What were the main features of the first generation of computers?

The main features of the first generation are −. Vacuum tube technology. Unreliable. Supported machine language only. Very costly. Generated a lot of heat. Slow input and output devices. Huge size. Need of AC. Non-portable. Consumed a lot of electricity Some computers of this generation were −.

What are the main features of the first generation of vacuums?

The main features of the first generation are −. Vacuum tube technology. Unreliable. Supported machine language only. Very costly. Generated a lot of heat. Slow input and output devices.

What are the advantages of second generation computer?

Learn Advantages of Second Generation Computer. Made use of vacuum tubes which are the only electronic component available during those days. Use of vacuum tube technology made possible to make an electronic digital computer. These computers could calculate in milliseconds.

Why was the first generation of computers so expensive?

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.
