What is a Second Generation of Computers?

The second generation of computers is a term used to describe a group of computers that were developed in the late 1950s and 1960s. These computers replaced vacuum tubes with transistors. Thus, making them smaller, faster, and more efficient.

The use of transistors in place of vacuum tubes made the systems much faster, smaller, and more efficient than 1st generation of computers. This change was done as transistors were more reliable than vacuum tubes, required less maintenance, and generated less heat. Thus, allowing computers to be smaller and more portable. These features of computers made them accessible to a wider audience.

The second generation of computers also saw the introduction of magnetic core memory, which was faster and more reliable than the first generation of computer memory. 

This introduction laid the foundation for further developments in the field. The development of computers in this era allowed for faster and more reliable processing, paving the way for the third generation of computers that used integrated circuits. Overall, the second generation of computers played a crucial role in shaping the modern computer technology we use today.

Characteristics of Second Generation of Computers

Here are the characteristics

  • Computers was smaller in size.
  •  Transistors were used instead of vacuum tubes
  • Computers were cheaper in cost than the earlier computers.
  •  Computers was faster at calculating data, taking only microseconds.
  •  Assembly language was used instead of machine language for programming.
  •  Computers required less energy and produced less heat than earlier versions of computers.

Advantages

Here are the advantages:

  • They offered better portability and smaller size.
  •  They provided better speed and improved accuracy.
  •  They were faster and widely used commercially, improving accuracy and offering better portability.
  • Computers were smaller, more reliable, and capable of using less power than the previous computers.

Disadvantages

Here are the disadvantages:

  • They were not very versatile and cheaper.
  •  They still required a cooling system even though they generated less heat.
  •  They were only used for specific objectives and required frequent maintenance.
  •  Even though they generated less heat, they still required air conditioning in the computer room.
  •  Computers used punch cards for input and required frequent maintenance.
  •  Commercial production of these computers was difficult and had a manual function component.
