Computer Generation

Generation of Computer:

Generation of Computer

First Generation
The period of first generation: 1946-1959. Vacuum tube based.
Vacuum tube produces lots of heat, and occupies huge space so the size of first generation computer is very high. It’s just start of new era.

Second Generation
The period of second generation: 1959-1965. Transistor based.
Transistor replaces the vacuum tube due to its smaller size, Cost and its Speed.
Third Generation
The period of third generation: 1965-1971. Integrated Circuit based.
IC's are used in third generation. Thousands of transistors are available on single chip. So its speed increases and size reduced to a single table.

Fourth Generation
The period of fourth generation: 1971-1980. VLSI microprocessor based.
VLSI circuits had about 5000 transistors. All high level programming languages are being used in this era.

Fifth Generation
The period of fifth generation: 1980-onwards. ULSI microprocessor based
Parallel processing hardware and AI (Artificial Intelligence) software are being used in fifth generation.

The field of Robotics, Gaming are growing in this generation.
