users can also use LAN for sending emails to thier friends or others users on the same network.the data can be transmitted faster and quicker between networked computers. a file server is also used to store information on each users day profiles this means that users can log onto any machine and log onto thier own network and access thier own files.

to log onto LAN you usually need to use a password and a username this identifies you to the file server so that it will serve you your own files or thge correct files.
