Software Computers that constantly run a control program, such as the computer in your car, are called embedded systems .
Software is the programs and data that a computer uses.
Software is kept on some hardware device such as a hard disk or floppy disk, but it itself is intangible. Say that you have a floppy disk with a program saved on it. Now say that you erase the program from the disk. The intangible software has been removed without removing anything tangible. Software consists of both programs and data .
