Software is a collection of instructions, data, or programs used to operate computers and execute specific tasks. In contrast to physical hardware, software comprises the intangible components of a computing system—code, data structures, and documentation—that instruct hardware to perform operations. The term 'software' originated in the late 1950s, differentiating these logical instructions from the 'hardware' of the machine itself. As the functional soul of all digital devices, software enables everything from basic arithmetic to complex artificial intelligence.
