| With a smaller computer, such as
PCs, a user can make use of the whole computer, use the whole of its
storage, and make use of all of its abilities. |
| Larger computers on the other hand are intended for many users
to use at the same time. To avoid having users seeing and damaging
each other's files the concept of 'user areas'
(also known as 'user accounts' or 'accounts') has been devised
where every user has his/her own part of the computer's storage. |

|
|
| To ensure that only the right user goes to the right area a special
name (the 'login' name) and password (the 'login' password) is given
to each user. |
|
The 'login' process is equivalent to having the number or name of
a room (the 'login' name) and a key to it (the 'login password').
'Logging in' or 'login' is the process of entering that room. The
name of the room may be known to many but as long as only one user
knows the password, the computer can ensure that only one user can
enter the room and look what is in it.
