Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.
