Computer software refers to programs that allow computers to perform tasks. There are several main types of software: system software runs computer hardware and systems, programming software assists programmers in writing code, application software allows users to perform specific tasks like word processing or playing games, and operating systems manage hardware/software resources and control input/output. The most common operating systems for personal computers are various versions of Windows, while popular applications include Word, web browsers, and games like The Sims. Computer games have evolved from simple titles to advanced visual games, though they sometimes face criticism for potentially influencing minors.
