Explanation

ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer.

ENIAC was completed in 1945 and first put to work for practical purposes on December 10, 1945.

Explanation

Vacuum tubes as the basic components for memory and circuitry for CPU .

These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.

First generation (1940 - 1956) vacuum tubes as a major piece of technology. 

The ENIAC is  example of 1st generation computer.

Second generation (1956 - 1963) use of transistors.

Third generation (1964 - 1971)  use of Integrated circuits.

Fourth generation (1972 - 2010) use of the microprocessor.

Fifth generation (2010 to present) use Artificial intelligence.

Explanation

The largest, fastest, and most expensive type of computer is the supercomputer.

These machines are used for specialized, complex tasks like weather forecasting, scientific research, and simulations that require immense computing power. 

Explanation

Microcomputers are also called personal computers (PCs). 

These are computers designed for individual use, which include desktops, laptops, and tablets.

Explanation

Explanation

Optical media such as compact discs (CDs) and digital versatile discs (DVDs).
