Anaccess point (AP)is a network device that extends the coverage of a wireless network by acting as a bridge between wired and wireless devices. It allows users to connect to a network without needing a direct wired connection. APs are particularly useful in large office spaces where Wi-Fi signals may not reach all areas.
