The third generation of computers brought forth a new wave of affordability and accessibility in computing. These were introduced in the 1960s and 1970s and used small electronic parts called transistors and integrated circuits. These new parts were much better than earlier computers' bulky and unreliable vacuum tubes.

What is a Third Generation of Computers?

Between the years 1964 and 1971, the third generation of computers emerged. The advent of microchips, a single piece of silicon (now know as - microchip or integrated circuit) that could house an entire circuit, revolutionized the industry and made the third generation possible.

This breakthrough led to the creation of smaller and cheaper computers that were much faster than the older computers. As a result, computers became more affordable, and more people began to show interest in programming and technology. This led to further advancements in computer programming and hardware.

With computational times slashed from microseconds to nanoseconds, the third generation of computers introduced new input devices such as the mouse and keyboard, which replaced the cumbersome punch cards of the past.

This era also saw the development of groundbreaking operating systems that supported multiprogramming and time-sharing, optimizing the use of computing resources and paving the way for remote processing—a feature that allowed computers to be accessed from different locations.

Programming languages, such as C, Pascal, COBOL, and FORTRAN, became increasingly popular. Magnetic storage also became more prevalent, offering a more efficient means of data storage and retrieval.

Characteristics of the 3rd Generation of Computers

  • Introduced new input devices like the mouse and keyboard.
  • Much faster computational time compared to previous generations.
  • Magnetic storage became more widely used, providing a more efficient way to store data.
  • Popular programming languages such as C, Pascal, COBOL, and FORTRAN were developed.
  • Remote processing was introduced, which allowed computers to be accessed from other locations.
  • Introduced new operating systems such as multiprogramming and time-sharing, allowing for more efficient use of resources.
  • Used smaller and more efficient electronic parts such as transistors and integrated circuits, allowing for more powerful and cheaper computers.
