User accounts are used to log into the system and provide one of the basic building blocks for permissions. You could loosely categorize users into a few categories:

• Regular user accounts like the one created for you during install.
• Accounts used to run specific processes. These users are often named after the service they run. For example the dbus users is user to run the master dbus process.
• The root account.
