Thales was the first to produce the electric sparks, rubbing the amber. The word "electricity" came into existence in 1600, thanks to scientist William Gilbert. In 1660, Otto von Guericke invented the electro static generator that generates static electricity -

First generation (1940 - 1956)
Vacuum tubes were larger components and resulted in first generation computers being quite large in size, taking up a lot of space in a room. Some of the first generation computers took up an entire room. The ENIAC is a great example of a first generation computer -

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. It´s smaller, faster and cheeper than the first generation computer. -

Third generation computers were computers that emerged due to the development of the integrated circuit (IC). Their main feature was the use of integrated circuits, which allowed them to be shrunk down to be as small as large toasters. EXAMPLES: PDP-8, PDP-11, ICL 2900, IBM 360, & IBM 370 are good examples for third generation computers. -

Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers.Many high-level languages were developed in the fourth generation such as COBOL, FORTRAN, BASIC, PASCAL and C language. -

James Maddox invented the fifth-generation computer. In the fifth generation, VLSI technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having ten million electronic components
