A wireless access point (WAP) is a networking device that allows wireless-capable devices to connect to a wired network. It serves as the interconnection point between the wireless local area network (WLAN) and a fixed wire network. Essentially, it creates a wireless LAN, usually in an office or large building, and connects to a wired router, switch, or hub via an Ethernet cable, projecting a WiFi signal to a designated area.
In summary, a wireless access point is a crucial component in providing wireless connectivity to devices within a network, allowing them to connect to a wired network and access the internet or other network resources.
