What are the main features of Multiuser operating system?

The main features of Multiuser operating system are as follows:

1. A multiuser operating system allows many different users to use computer's resources simultaneously.
2. Each user can work on different set of programs and data. In such an environment, programs and data of more than one user are loaded into the memory and processed by the operating system.
3. There is a central computer (CPU) that acts as a server and all the other computers are connected to the server with the help of terminals.
4. Each user has sufficient and separate resources, so that a problem with one user does not affect the entire community of users.
5. Multiuser operating systems run and manage all users' requests simultaneously, ensuring that they do not interfere with each other.
