access point - Computer Definition
A base station in a wireless LAN. Although there are other wireless technologies that use access points, the term generally refers to a Wi-Fi network. Access points (APs) are stand-alone devices that plug into an Ethernet switch or hub; however, access point functionality is also built into a router (see wireless router). Like a Cellular Phone System Multiple access points can be deployed in an organization, and users roaming with their mobile devices are handed off from one access point (AP) to another. AP Name = Service Set Identifier (SSID) Wi-Fi networks are assigned a name by the user or network administrator. When devices search for Wi-Fi networks, they display the names, called "service set identifiers" (SSIDs), of all the Wi-Fi access points in the vicinity. For more details, see SSID.
