+ | ====== Access Network ====== | ||
+ | |||
+ | An //access network// is the name given to the part of the Internet or intranet that is closest to the host or [[end-system]]. It connects the end-system to the first router. Examples of access networks are: | ||
+ | * [[Ethernet]] [[lan|Local Area Network]] (LAN) such as you may find in a University laboratory or at home if you have an Ethernet switch connected to your Broadband modem. | ||
+ | * Wireless ([[WiFi]]) router: provides an //access point// which is usually connected to a wired institional or home network. | ||
+ | * Dial-up modem: such as for data over telephone. | ||
+ | * [[Broadband]]: | ||
+ | * Mobile telephone network: provides an access point that uses [[3G]] or [[GSM]] networks and provides connectivity for mobile devices over a wide geographic area. | ||
+ | |||
+ | In each case, the so called "last link" will be connected to a router that provides access, using internet protocols, to the wide area network. Thus an access network is the link netween the //network edge// and the //network core//. | ||
