What are the Responsibilities of system software?

Answer 1

Wikipedia:

System software is closely related to, but distinct from Operating System software. It is any computer software that provides the infrastructure over which programs can operate, ie it manages and controls computer hardware so that application software can perform. Operating systems, such as Microsoft Windows, Mac OS X or Linux, are prominent examples of system software. System software is software that basically makes the computer work. Besides operating systems, other examples are anti-virus software, communication software and printer drivers. Without the system software the computer doesn't work. In contrast to system software, software that allows you to do things like create text documents, play games, listen to music, or surf the web is called application software.[1] In general application software are programs that enable the end-user to perform specific, productive tasks, such as word processing or image manipulation. System software performs tasks like transferring data from memory to disk, or rendering text onto a display device.
