Introduction
The Generation of Computer Evolution is Generally Divided Into 5 Categories.
The First Generation of Computers- (the 1940s-1950s)
- The main electronic component used in the computers of the 1940s to 1950s era were vacuum tubes.
- The main memory storing units were magnetic tapes and magnetic drums.
- The machine language was used as the programming language.
The Second Generation of Computers- (the 1950s-1960s)
- The main electronic component used in the computers of the 1950s to 1960s era were transistors.
- The main memory storing units were magnetic tape or disk and magnetic core.
- The assembly language was used as the programming language.
The Third Generation of Computers- (the 1960s-1970s)
- The main electronic components used in the computers of the era 1060s to 1970s were integrated circuits ICs.
- The memory storing units were the magnetic disk or take and a large magnetic core.
- High-level languages such as BASIC, COBOL, Pascal were used as the programming language.
The Fourth Generation of Computers- (1970s-present)
- The main electronic components used in the fourth generation of computers are microprocessors and very large scale integration (VLSI).
- When thousands of transistors are attached to a single microchip, it is known as VLSI
The Fifth Generation of Computers- (present and the future)
- 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).
- The fifth generation of computers understands the natural human language.
- The speeds are really fast and the sizes are also small.
