What role does an Access Point (AP) play in network topology?

An Access Point (AP) serves as a bridge between wired and wireless LANs by enabling wireless devices to connect to a wired network. It facilitates communication between the wireless clients (like laptops, smartphones, and tablets) and the wired infrastructure of the network, allowing those devices to access network resources such as printers, file servers, and the internet.

When a wireless device connects to the AP, it transmits data wirelessly, and the AP converts those wireless signals into a format that can be understood by the wired network. This bridging function is essential in extending the range of a local area network and ensuring seamless connectivity for users within the coverage area of the AP.

In contrast, the other options do not accurately describe the primary function of an Access Point. While firewalls do protect networks, that's not the role of an AP. Similarly, while APs do relate to signal conversion, their main function is more focused on the connection and bridging. Tracking network traffic for malicious activity falls under the domain of intrusion detection or prevention systems (IDS/IPS) rather than the function of an Access Point.
