What is Unics (Uniplexed operating system)?
Ken Thompson (one of the Multics developers) joined with Dennis Ritchie and team members to develop new multi-tasking operating system called UNICS (Uniplexed Operating and Computing System). This is considered the first UNIX operating system. UNIX was designed to be portable, multi-tasking and multi-user in a time-sharing configuration.
Why is Unix called a multi-user operating system?
Several people can use a UNIX computer at the same time; hence UNIX is called a multiuser system. A user can also run multiple programs at the same time; hence UNIX is called multitasking. Single-user, single-process operating systems: Allow only one user at a time to use the computer system.
