In computer networking, a wireless access point, or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. As a standalone device, the AP may have a wired connection to a router, but, in a wireless router, it can also be an integral component of the router itself. An AP is differentiated from a hotspot which is a physical location where Wi-Fi access is available.
Although WAP has been used incorrectly to describe an Access Point, the clear definition is Wireless Application Protocol which describes a protocol rather then a physical device.
An AP connects directly to a wired local area network, typically Ethernet, and the AP then provides wireless connections using wireless lan technology, typically Wi-Fi, for other devices to use that wired connection. APs support the connection of multiple wireless devices through their one wired connection.
