What is the difference between multi-user operating systems and single-user operating systems?
The main difference between a single-user and a multi-user operating system is that in a single-user operating system, only one user can access the computer system at a time; in contrast, in a multi-user operating system, multiple users can access the computer system simultaneously.
How does the multi-user operating system work?
A multi-user operating system is a computer operating system that allows multiple users to access one system with one operating system on it. Several users access the machine running the operating system through network terminals. The operating system can handle requests from users by switching between connected users in turn.
