Computer software

Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware).
This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software.

Practical computer systems divide software into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred. Computer software has to be "loaded" into the computer's storage (such as a hard drive, memory, or RAM).
