Question

1 Explain the generation of computer.​

Answer 1

$\huge\underline\bold\pink{Solution:-}$

First-generation computers:

The first computers used vacuum tubes for electronic circuitry and magnetic drums for memory. They were very expensive to operate and the power consumption was high, generated a lot of heat, which was often the cause of malfunctions.

Second-generation computers:

In the second generation computers, symbolic or assembly languages were used. High-level programming languages were also in use at this time, such as early versions of COBOL and FORTRAN. Their memory consisted of magnetic core technology.

Third-generation computers:

The development of the integrated circuit was made use of the third generation computers. Transistors were miniaturized and were placed on silicon chips, called semiconductors.

• The processing speed and efficiency of computers increased.
• Keyboards and monitors were used as input and output devices.
• Computer system had an operating system and helped to run multiple applications simultaneously.

Fourth-generation computers:

The microprocessor was used in the fourth generation computers, as thousands of integrated _ circuits were built onto a single silicon chip. The Intel 4004 chip, developed in 1971, located all the components of the computer – from the central processing unit and memory to input/output controls – on a single chip.
