Linux is a Multi-User Operating System. It means multiple users can access the system and hardware at the same time.
This is quite helpful in large organizations as it:
1. Improves productivity.
2. Reduces required hardware.
3. Provides access control for different users.
A multiple-user operating system is very efficient as all the users can access a file at the same time. It can perform multiple tasks at the same time. Other examples of Multi-User operating systems include Unix and Windows.
The system administrator provides the user with different access to ensure the stability of the system. This is done by adding users to different user groups. The system administrator then provides different permissions to these user groups. These permissions decide which user group can access particular hardware, files, etc.
