Verified Answer
Which electronic components were used in Fourth Generation Computers?...
Fourth Generation (1978 - present):
  • An IC containing about 100 components is called LSI (Large Scale Integration) and the one, which has more than 1000 such components, is called VLSI (Very Large Scale Integration).
  • It uses large-scale Integrated Circuits(LSIC) built on a single silicon chip called microprocessors.
  • Due to the development of the microprocessor, it is possible to place a computer's central processing unit(CPU) on a single chip.
  • These computers are called microcomputers.
  • Later very large scale Integrated Circuits(VLSIC) replaced LSICs. Thus the computer which was occupying a very large room in earlier days can now be placed on a table.
  • The personal computer (PC) that can be seen in school is a Fourth Generation Computer.
  • Some of the Fourth generation computers are IBM PC, Apple-Macintosh, etc.
  • Hard disks were used as secondary memory.
  • Keyboards, dot matrix printers, etc., were developed.
  • Operating System (OS)-such as MS-DOS, UNIX, Apple's Macintosh was available.
  • An object-oriented language, C++, etc. were developed.

Which electronic components were used in Fourth Generation Computers?...
Fourth Generation Computers and Electronic Components Used

Fourth generation computers were designed in the mid-1970s and were characterized by the use of microprocessors, VLSI circuits, and high-level programming languages. The electronic components used in fourth generation computers were:

1. VLSI (Very Large Scale Integration) Circuits:

VLSI circuits are integrated circuits that contain millions of transistors on a single chip. They were first introduced in the 1970s and revolutionized the computer industry by making it possible to create smaller, faster, and more powerful computers.

2. Microprocessors:

Microprocessors are electronic chips that contain the CPU (Central Processing Unit) of a computer. They were first introduced in the early 1970s and were used in fourth generation computers to provide faster processing speed and better performance.

3. High-Level Programming Languages:

High-level programming languages are computer languages that are easier to read and write than low-level languages like assembly language. They were used in fourth generation computers to make programming easier and more accessible to a wider range of people.

4. Operating Systems:

Operating systems are software programs that manage the resources of a computer and provide an interface for users to interact with the computer. Fourth generation computers used advanced operating systems like UNIX and MS-DOS that were designed to be more user-friendly and efficient.

Conclusion:

In summary, fourth generation computers were characterized by the use of VLSI circuits, microprocessors, high-level programming languages, and advanced operating systems. These electronic components were instrumental in making computers smaller, faster, and more powerful, and paved the way for the development of modern computers that we use today.
