WHAT IS A SOFTWARE A set of instructions that cause a computer to perform one or more tasks. The set of instructions is often called a program or‚ if the set is particularly large and complex‚ a system. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. A program must tell the computer each of a set of minuscule tasks to perform‚ in a framework of logic‚ such that the computer
