An administrator can change the following settings in Settings > Site administration > Server > Session Handling.

Timeout

Once someone logs in to your Moodle server, the server starts a session. The session data allows the server to track users as they access different pages. If users don't load a new page during the amount of time set here, Moodle will end their session and log them out.

Be sure this time frame is long enough to cover the longest test your teachers may offer. If a student is logged out while they are taking a test, their responses to the test questions may be lost.

Cookie prefix

Most of the time, you can leave this blank, unless you are running more than one Moodle site on the same server. In this case, you will want to customize the name of the cookie each Moodle site uses to track the session. This enables you to be logged into more than one Moodle site at the same time.

Note: If you change "Cookie prefix" or "Cookie path" you will need to login again as the changes take effect immediately.

Session drivers

User sessions may be stored in different backends. Session drivers can be configured only in config.php file - see examples in config-dist.php file.

Memcache

Memcached session driver is the fastest driver, it requires external memcache server and memcached PHP extension.

Files

File based session require file system that supports file locking. This driver is used by default in new installation.

Database

This driver was used by default in Moodle 2.0-2.5.
