The operating system is the software that directly controls the computer and other hardware, providing support services to other software, such as applications. Applications are what most people work with most of the time, and include word processors, spreadsheets, Internet software, games, and so on. Examples of operating systems on small computers include various versions of DOS, the Macintosh OS, and Windows. Some operating systems are designed for specific computers. Others, such as UNIX and LINUX, are designed to provide a generalized interface for many types of computers
