A multi-user operating system is one that allows for multiple users to use the same computer at the same time and/or different times. In computer networking, a multi-user system is a term commonly used to define a computer capable of allowing multiple users to connect to a network. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users.
These are Operating systems that allow different parts of a software program to run concurrently. Multi threading is the ability of a program or an operating system to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer. Each user request for a program or system service is kept track of as a thread with a separate identity.
