First Computer Invented
The ENIAC was invented by J. Presper Eckert and John Mauchly -
Second Generation- Transistors
The period of second generation was 1959-1965. In this generation transistors were used that were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes. The computers used batch processing and multiprogramming operating system. -
Third Generation-Integrated Circuits
Computers of third generation used integrated circuits (IC's) in place of transistors. A single IC has many transistors, resistors and capacitors along with the associated circuitry. The IC was invented by Jack Kilby. -
4TH Generation-Microprocessors
The fourth generation computers have microprocessor-based systems.They are the cheapest among all the computer generation.The speed, accuracy and reliability of the computers were improved in fourth generation computers.Many high-level languages were developed in the fourth generation such as COBOL, FORTRAN, BASIC, PASCAL and C language. A Further refinement of input/output devices was developed.Networking between the systems was developed. -
Fifth Generation-Artificial Intelligence Computers
Scientists are working hard on the 5th generation computers with quite a few breakthroughs. It is based on the technique of Artificial Intelligence (AI). Computers can understand spoken words & imitate human reasoning. Can respond to its surroundings using different types of sensors. Scientists are constantly working to increase the processing power of computers. They are trying to create a computer with real IQ with the help of advanced programming and technologies.
