1st Generation
The first generation used vacuum tube technology and were built between 1946 and 1959. Vacuum tubes were expensive and produced a lot of heat, which made these computers very expensive and only affordable to large organizations. Machine language was the programming language used for these computers, and they could not multitask. -
1st Generation
The First ENIAC computer -
2nd Generation
The second generation computers were used during 1957-1963. They are also known as transistor computers. The second generation of computers consists of two types of devices, transistors, and magnetic core. -
Period: to
2nd Generation
Computers developed between 1959-1965 the second generation computers. These computers were more reliable and in place of vacuum tubes, used transistors. This made them far more compact than the first generation computers. The input for these computers were higher level languages like COBOL, FORTRAN etc. -
3rd Generation
A third-generation computer refers to a type of computer that emerged in the 1960s and featured integrated circuits. These computers were smaller, more reliable, and faster than their predecessors -
3rd Generation
The third generation computer was started in 1965 and ended around 1971. Third generation computers start using integrated circuits instead of transistors. The integrated circuit (IC) is a semiconductor material, that contains thousands of transistors miniaturized in it. -
4th Generation
The fourth generation computers was developed using microprocessor. Intel 4004 chip was the first microprocessor developed in 1971. The microprocessor is a silicon chip contains millions of transistors that was designed using LSI and VLSI technology. -
Period: to
4th Generation
Fourth Generation of computers was between 1971 – 1980. These computers used the VLSI technology or the Very Large Scale Integrated (VLSI) circuits technology. Therefore they were also known as the microprocessors. Intel was the first company to develop a microprocessor. -
Period: to
5th Generation
The fifth gen of computers is the most recent and advanced computers. These computers use programming languages such as Python, R, C#, Java, etc., as input methods. These computers are extremely dependable and employ ULSI technology.
