Relationship between users and tasks in Linux

Relationship between users and tasks in Linux-general Linux technology-Linux technology and application information. For more information, see the following section. Understand the concept of single-user multitasking and multi-user multitasking in Linux

Linux single-user multitasking
A single user has multiple tasks. A single user executes multiple tasks to complete the work. Of course, other users can log on remotely and do other work.

Multi-user and multi-task in Linux
Sometimes many users use the same system at the same time, but not all users must do the same thing, so there are multiple users and multiple tasks;

For example, if a server contains FTP users, system administrators, web users, and common users, some may upload software packages to manage the sub-stations at the same time, there may also be system administrators who are maintaining the system. Different users have different permissions. Different users are required to complete different tasks, the work may be different;

It is worth noting that the multi-user multi-task operation is not performed by the keyboard and display of a single machine at the same time. Multiple users may log on remotely, for example, remote control of the server, anyone with user permissions can perform operations or access.
