System software consists of a variety of programs that support the operation of a computer. It is a set of programs to perform a variety of system functions as file editing, resource management, I/O management and storage management. The characteristic in which system software differs from application software is machine dependency. An application program is primarily concerned with the solution of some problem, using the computer as a tool. System programs on the other hand are intended to support the operation and use of the computer itself, rather than any particular application. For this reason, they are usually related to the architecture of the machine on which they are run. For example, assemblers translate mnemonic instructions into machine code. The instruction formats, addressing modes are of direct concern in assembler design. There are some aspects of system software that do not directly depend upon the type of computing system being supported. These are known as machineindependent features. For example, the general design and logic of an assembler is basically the same on most computers.
