Software is a set of instructions, data, or programs that tell a computer how to perform a task, operating on the intangible side of a computer system, unlike its physical hardware. It is a broad term that encompasses both the system software, such as the operating system, and application software, like word processors and web browsers, that allow users to interact with a device.

Key aspects of software:

Instructions: Software is fundamentally a series of commands written in code that a computer executes.

Intangible: It is the opposite of hardware, which are the physical, touchable components of a computer.

Functionality: It enables a computer to perform specific tasks, ranging from managing the system to running specific applications like a web browser or video editor.

Categories:

System Software: Manages the computer's internal functions, including the operating system and drivers for peripherals like printers.

Application Software: Directs the computer to perform specific tasks for the user, such as writing a document or playing a game.
