Local Area Networks
-
LANs link several computers to each other within a small physical area, such as a single office building. The main storage device (essentially the "brain") of the LAN -- the server -- allows any computer logged in and linked to the LAN to access files or data stored on it.
Remote Access
-
While a LAN links computers in a smaller, physical location, remote access can connect one computer to another computer or network far away. Remote access uses Internet technology to link, for instance, your home computer to the computer you use at work.

Hazards and Limitations
-
As with all networks, security concerns for LANs and remote access networks make protection with firewalls and passwords a must. Remote access also tends to move much slower than when you sit at the computer storing the data and access it directly.
