Generation of computer

First Generation : (1940-1956) The first Generation of Computer used vacuum tubes for circuitry and magnetic for memory. it can solve only one problem at a time.

Second Generation: (1950-1960) The Second Generation of computers replace a vacuum tube by transistors, Transistors used the punched card for input and print out for output.

Third Generation: (1965-1971) Transistors were made smaller in size and placed on silicon chips. it increased the speed and efficiency of the computer, it can solve many problems at a time.

Fourth Generation: (1971-1980) Thousands of Integrated Circuits (IC) built onto single silicon is called microprocessor as these small computers become more powerful.

Fifth Generation: the Fifth generation of computer is based on parallel processing hardware and AI (Artificial Intelligence), They use ultra large scale integration (ULSI) technologies. The aim of the fifth generation is to make a device that could respond to natural language input like image recognition, graph recognition, and Speech recognition and are capable of learning and self-organization.
