Software refers to a set of instructions or programs that tell a computer or other electronic device what tasks to perform. Software can be divided into two broad categories: system software and application software. System software is designed to manage and control the hardware and resources of a computer or electronic device. Examples of system software include operating systems, device drivers, firmware, and utility programs. Application software, on the other hand, is designed to perform specific tasks or applications for the user. Examples of application software include word processors, spreadsheets, graphic design software, web browsers, and video editing software.
