Which operating system model allows multiple users to share resources?

The multi-user operating system model is designed to support multiple users simultaneously, allowing them to share the system's resources such as CPU time, memory, and storage. This model enables several users to work on the same system at the same time, each with their own user accounts and sessions. Multi-user operating systems often manage access to shared resources to ensure that users can operate independently without interfering with one another's tasks.

This capacity for concurrent access to system resources is vital for environments where collaboration and resource sharing are essential, such as in corporate networks or server farms. The multi-user model is suited for situations where many individuals need to perform tasks concurrently, facilitating processes such as remote login, user management, and resource allocation without conflicts or disruptions.
