Software is a collection of instructions and data that tell the computer how to work. This is in contrast to physical hardware , from which the system is built and actually performs the work. In computer science and software engineering , computer software is all information processed by computer systems , including programs and data. Computer software includes computer programs , libraries and related non-executable data , such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own. At the lowest programming level , executable code consists of machine language instructions supported by an individual processor —typically a central processing unit CPU or a graphics processing unit GPU.
