- The magnetic core was used as the primary memory.
- Magnetic tapes and disks were used as secondary storage devices.

Question: Write about Fourth Generation of computers. 
Answer: The time interval of fourth-generation computers was from 1975 to 1989. Computers of this generation used VLSI circuits. These circuits made it possible to build fourth-generation’s Microcomputers. Computers of this generation were very powerful, small, and reliable.

Long Answer Type Questions:

Question: What do you mean by Generation of Computers? How are they classified?
Answer: In the technical terminology of computers, a Generation means the change in computer technology. Till know, Computer Generations have been classified into total five generations which are as follows:
- First Generation Computers (1942-1955)
- Second Generation Computers (1955-1964)
- Third Generation Computers (1964-1975)
- Fourth Generation Computers (1975-1989)
- Fifth Generation computers (1989 – present)

Question: Explain Fifth Generation of Computers.
Answer: The time period of fifth generation computers is from 1989- till date. Fifth Generation computers use ULSI (Ultra Large-Scale Integration) technology. These ULSI Microprocessor chips contain tens of millions of electronic components. Computers of this generation works on the basis of Parallel Processing hardware and Artificial Intelligence (AI) software. All high-level languages like: C, C ++, Java, .Net, etc. are used in the computers of this generation.
