What is a Computer?

A computer is an electronic device that processes data by following a set of instructions (software) to perform a variety of tasks. These tasks can range from simple calculations to complex problem-solving processes. Computers work by converting data into binary code (0s and 1s) and using that code to execute operations. There are various types of computers, including personal computers (PCs), servers, mainframes, and supercomputers.

Brief History of Computers

Key Milestones in Computer Development

1. 1950s–1960s: Introduction of Programming Languages like FORTRAN, COBOL, and later C and BASIC.
2. 1970s: The birth of personal computing with systems like the Altair 8800 and Apple I.
3. 1980s: Rise of the Graphical User Interface (GUI) with systems like Apple Macintosh and Windows.
4. 1990s: Growth of the internet and its role in personal and business computing.
5. 2000s-present: Emergence of mobile computing, cloud services, and the advancement of AI and quantum computing.

This evolution has transformed computers from basic calculating machines into powerful tools integral to nearly every aspect of modern life.
