The development of electronic computers is divided into 5 generations relying upon the technologies used. The subsequent are the 5 generations of computers.

First Generation: Vacuum Tubes

The first laptop systems used vacuum tubes for electronic equipment and magnetic drums for memory, and were usually monumental, taking over entire rooms. These computers were terribly costly to control and additionally to employing a wad of electricity, the primary computers generated lots of warmth that was usually the reason behind malfunctions.

First generation computers relied on machine language, the lowest-level artificial language understood by computers, to perform operations, and that they might solely solve one drawback at a time. it might take operators days or maybe weeks to set-up a brand new drawback. Input was supported punched cards and paper, and output was displayed on printouts.

Second Generation: Transistors

The second generation computers used transistors. The scientists at Bell laboratories developed junction transistor in 1947. These scientists embrace John Barden, William Brattain and William Bradford Shockley. The dimensions of the computers were diminished by commutation vacuum tubes with transistors. The samples of second generation computers are IBM 7094 series, IBM 1400 series and government agency 164 etc

From Binary to Assembly

Second-generation computers affected from cryptic binary machine language to symbolic, or assembly, languages, that allowed programmers to specify directions in words. High-level programming languages were conjointly being developed at this point, like early versions of COBOL and FORTRAN. These were conjointly the primary computers that keep their directions in their memory that affected from a magnetic drum to core technology.

Third Generation: Integrated Circuits

The development of the microcircuit third generation of computers. Transistors were miniaturized and placed on atomic number 14 chips, known as semiconductors that drastically inflated the speed and potency of computers.

Computers for the primary time became accessible to a mass audience as a result of they were smaller and cheaper than their predecessors.

Fourth Generation:  Microprocessors

The fourth generation computers started with the invention of microchip. The microchip contains thousands of ICs. Plug-ugly Hoff made the primary microchip in 1971 for Intel. it had been referred to as Intel 4004. The technology of integrated circuits improved quickly. The LSI (Large Scale Integration) circuit and VLSI (Very giant Scale Integration) circuit was designed. It greatly reduced the dimensions of laptop. The dimensions of recent Microprocessors are sometimes one sq in. It will contain innumerable electronic circuits. The samples of fourth generation computers are Apple Macintosh & IBM laptop.

As these tiny computers became additional powerful, they might be coupled along to make networks, that eventually diode to the event of the net. Fourth generation computers conjointly saw the event of GUIs, the mouse and hand-held devices.

Fifth Generation: Artificial Intelligence (Present and Beyond)

Fifth generation Artificial Intelligence devices, supported Artificial Intelligence, are still in development, although there are some applications, like voice recognition, that are being employed nowadays. the employment of multiprocessing and superconductors helps to form Artificial Intelligence a reality.

Quantum computation and molecular and engineering science can seriously change the face of computers in years to return. The goal of fifth-generation Artificial Intelligence is to develop devices that answer tongue input and are capable of learning and organization.
