What is Computer Generation?

Computers have become an integral part of our everyday life.

The computer’s history goes back several decades. However, there are five generations of computer that are definable.

The generations are defined by significant technological development that changes fundamentally how computers operate.

Basically, the history of computer development is a computer science topic. This topic is often used to reference the different generations of computing devices. Each generation of computer is characterized by a major technological development which has fundamentally changed the way computers operate.

From the 1940s to the present day, the most major developments have resulted in increasingly smaller, cheaper, more powerful, more efficient, and lighter weight computing devices.

Five generations of computers

  1. First Generation: Vacuum Tubes
  2. Second Generation Transistors
  3. Third Generation: Integrated Circuits
  4. Fourth Generation: Microprocessors
  5. Fifth Generation: Artificial Intelligence

 

Second Generation: Transistors (1956-1963)

This generation used transistors instead of vacuum tubes. From 1956 to 1963, transistors were widely used in computers. Transistors were smaller as compared to vacuum tubes.

It allowed computers to be smaller in size. Because of transistors, second generation computers were faster in speed and cheaper to build.

An example is TX-0 and it was introduced in 1956. Some other computers that used transistors were IBM 7070, RCA 501, and Philco Transac S-1000.

Advantages of second generation computers:

You can see here. Advantages of second generation

  • Transistors decreased the size of the electron component.
  • The size of the computer was smaller as compared to the first generation computer.
  • It used less energy.
  • It did not produce much heat.
  • Punch cards and assembly language were used for input.
  • They were low cost.
  • They had better speed.
  • They used to calculate data in microseconds.
  • Better portability

Disadvantages of the second generation:

  • They needed a cooling system.
  • The constant maintenance was required.
  • These computers were only used for specific purposes.
