What is the function of a switch in a network?
Correct Answer: D. To forward data only to the intended device
The function of a switch in a network is to forward data only to the intended device based on its MAC address. Unlike a hub, which broadcasts data to all connected devices, a switch intelligently sends data only to the recipient device, reducing unnecessary traffic and improving network efficiency. This selective forwarding enhances performance and security in both small and large network environments.
Why Other Options are Incorrect:
A. To connect different networks
Connecting different networks is the role of a router, not a switch. Routers operate at the network layer and direct traffic between separate networks, whereas switches operate at the data link layer within a single network.
B. To assign IP addresses
Assigning IP addresses is the function of a DHCP (Dynamic Host Configuration Protocol) server. Switches do not handle IP addressing; they work with MAC addresses to forward data within a network.
C. To filter network traffic by content
Filtering traffic by content is typically performed by a firewall or content filter. Switches manage traffic based on MAC addresses and forwarding rules, not the actual content of the data packets.
