4.2. What is an Access Point?

An Access Point (AP) is a networking device that allows wireless-capable devices to connect to a wired network, typically via Wi-Fi. It serves as a central hub for wireless communication, transmitting and receiving radio signals to enable data exchange between wireless clients (e.g., phones, laptops) and the wired network (e.g., a router or switch connected to the internet).

Key Role: Acts as a bridge or translator between wireless (radio-based) and wired (Ethernet-based) networks.

Common Use Cases: Home Wi-Fi networks, enterprise WLANs, public hotspots (e.g., coffee shops, airports), and IoT device connectivity.
