Question

Quizplus · Accepted Answer

Switches learn addresses by reading the source and destination addresses of incoming packets at the data link layer. They use this information to create a table of MAC addresses and their associated ports, which allows them to forward traffic more efficiently. Switches operate at the data link layer and can also provide some functionality at the network layer, such as VLANs, but they do not connect networks that use different data link or network protocols. Additionally, switches are still widely used in networking and have not become less popular than hubs.
