A real-time operating system may be single- or multi-tasking, but when multitasking, it uses specialized scheduling algorithms so that a deterministic nature of behavior is achieved. Retrieved 21 December 2009. ^ "The History of Unix". Single- and multi-user Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem.[5] A multi-user operating system extends the basic concept of multi-tasking Other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications.

In the late 1960s such a machine would have been nearly as large as two desks and would have weighed about half a ton.[18] A seminal step in personal computing was The very earliest microcomputers, equipped with a front panel, required hand-loading of a "bootstrap" program to load programs from external storage (paper tape ("punched tape"), tape cassettes, or eventually diskettes). It explains in computing terminology what Wizard means and is one of many software terms in the TechTerms dictionary. Since programs time share, each program must have independent access to memory.
