Have no facilities to distinguish users, but may allow multiple programs to run in tandem.

• real-time
• single-user
• multi-user
• multi-tasking

Extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, and the system permits multiple users to interact with the system at the same time.
