Introduction

The Generation of Computer Evolution is Generally Divided Into 5 Categories.

The First Generation of Computers- (the 1940s-1950s)

1. The main electronic component used in the computers of the 1940s to 1950s era were vacuum tubes.
2. The main memory storing units were magnetic tapes and magnetic drums.
3. The machine language was used as the programming language.

The Second Generation of Computers- (the 1950s-1960s)

1. The main electronic component used in the computers of the 1950s to 1960s era were transistors.
2. The main memory storing units were magnetic tape or disk and magnetic core.
3. The assembly language was used as the programming language.

The Third Generation of Computers- (the 1960s-1970s)

1. The main electronic components used in the computers of the era 1060s to 1970s were integrated circuits ICs.
2. The memory storing units were the magnetic disk or take and a large magnetic core.
3. High-level languages such as BASIC, COBOL, Pascal were used as the programming language.

The Fourth Generation of Computers- (1970s-present)

1. The main electronic components used in the fourth generation of computers are microprocessors and very large scale integration (VLSI).
2. When thousands of transistors are attached to a single microchip, it is known as VLSI

The Fifth Generation of Computers- (present and the future)

1. The main electronic components that are used in the present generation of computers is Artificial Intelligence which uses the parallel processing method and the Ultra-Large Scale Integration (ULSI).
2. The fifth generation of computers understands the natural human language.
3. The speeds are really fast and the sizes are also small.
