What is the role of an access point in a network?

The role of an access point in a network is to connect wireless devices to a wired network. Access points extend a wired network by providing a wireless interface, allowing devices such as laptops, smartphones, and tablets to communicate over the network without needing a direct physical connection. They typically connect to a router or switch via Ethernet and enable devices to connect to the network wirelessly.

This functionality is crucial in environments where cabling is impractical or where mobility is essential, such as in offices, schools, and public spaces. Access points can also facilitate network management and security features, such as the ability to limit access to authorized devices or to manage network traffic effectively.
