What is the purpose of a VLAN in switching?

Step 1: Understand that a VLAN stands for Virtual Local Area Network.
Step 2: Know that a VLAN is used in networking to create separate groups within a larger network.
Step 3: Realize that these groups can help manage network traffic more efficiently.
Step 4: Learn that VLANs allow different departments or teams to have their own network space, even if they are on the same physical network.
Step 5: Understand that this separation helps improve security by isolating sensitive data from other parts of the network.
Step 6: Remember that VLANs can also reduce network congestion by limiting broadcast traffic to only the devices in the same VLAN.
