Explanation:

Switches operate atLayer 2andLayer 3of the OSI model. Here's a brief explanation for each layer:

Layer 2 (Data Link Layer):

Switches primarily operate at this layer.

They use MAC addresses to forward frames within a local network (LAN).

Switches create and maintain MAC address tables to make forwarding decisions.

Examples of switches include Ethernet switches and VLAN switches.

Layer 3 (Network Layer):

Some advanced switches (known asLayer 3 switches) can perform routing functions.

Layer 3 switches can route traffic between different subnets within the same LAN.

They use IP addresses to make routing decisions.

Layer 3 switches combine the features of switches and routers.
