What is Computer ?
 A computer is a programmable electronic device that processes data and performs
various tasks according to a set of instructions called a program. It is a versatile tool
used for a wide range of applications, including calculations, data storage,
communication, and multimedia processing. Computers can be found in various
forms, such as personal computers, laptops, servers, mainframes, and embedded
systems in everyday devices.

Generation of computer : The evolution of computers is often categorized into different


generations, each marked by significant advancements in hardware and technology. The
concept of computer generations helps to understand the major changes and improvements
that have occurred over time. As of my last knowledge update in January 2022. Such as-
 First Generation (1940s-1950s)
 Second Generation (1950s-1960s)
 Third Generation (1960s-1970s)
 Fourth Generation (1970s-1980s)
 Fifth Generation (1980s-Present)
