Computer languages and operating systems. What they are and how they work.
Programs (software) make a computer's circuits (hardware) perform useful work. This article reviews briefly how computers are programmed, beginning with the storage of data and program instructions. A simple description of how a computer executes a sequence of instructions (program) is followed by the basic concepts of machine-language and assembly-language programming. An overview of higher-level computer languages and a description of the distinction between systems and applications programs are also included.
