Software is the intangible, code-driven component of computer systems that instructs hardware on how to perform specific tasks. It comprises programs, applications, and algorithms that enable computers to process data and execute functions. Software can be broadly categorized into two main types: system software, which manages the hardware and provides a platform for other software to run, and application software, which fulfills specific user tasks. From operating systems like Windows, and Linux that govern overall system operations to a multitude of applications such as word processors, web browsers, and design tools, software is the driving force behind the functionality and utility of modern computing devices.
