The User Model
Since Linux is a true multi-user
operating system, gaining access to the system is somewhat different
from DOS, Windows95, or Windows98 systems. Although those systems can
be somewhat secured and may require a password for access, once the
user has access to the desktop, the user can do anything to the system,
including changing what would normally be considered administrative
items such a system configuration, installing software, changing hardware,
and other such functions. In the Linux model, there are standard users’
accounts, which have limited access, and only the root, or super user
account from which system administrative functions are performed. This
Linux system is similar to the user/admistrator account system in WindowsXP
