Networks used by large companies and school campuses include additional network devices not usually found in a home. These include servers, which are powerful computers that store files and programs and manage access to the network through stored passwords. Large networks also use advanced networking devices like switches, firewalls and routers. These networking devices essentially do what a home router does by managing traffic and directing data to the right devices; however, they have advanced management software and can handle anywhere from a few dozen to a few thousand connections simultaneously.
