Access Point (AP)
A wireless access point enable you to connect to the internet.
In Computer Networking an 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.
Difference with Hotspot?
AP = physical location where Wi-Fi access is available Hotspot = software enabled access to the internet
