As a system operator you are responsible for performing tasks that monitor system activity. These tasks include managing the console, communicating with your users, and managing activities for jobs and sessions.

The system console, also referred to as the console, is a terminal connected to your computer. It responds to a special set of commands that are not available on other terminals. By using these commands, you can get a comprehensive picture of all system activity.

A session is a two-way dialog between a user and the computer. The computer interprets and follows the commands you enter at the keyboard, if it can. If it cannot, it uses an error message to tell you that something is wrong. A job is a sequence of instructions given to the computer to process. When you store this information in a job file, and then execute it, you create a job.
