Software refers to the programs and applications that run on your computer or device, allowing you to perform various tasks. It includes everything from operating systems, like Windows or macOS, which manage your device’s basic functions, to applications like web browsers, games, and word processors. Software tells the hardware (like your computer’s CPU and memory) what to do and how to do it. It can be downloaded or installed and often needs updates to fix bugs or add new features. In simple terms, software is what makes your device useful and helps you get things done.
