1. What is a VLAN?

A VLAN (Virtual Local Area Network) is a logical division of a physical LAN into multiple broadcast domains. It allows you to segment a network by grouping devices together logically, even if they are physically located on different switches. VLANs enhance network security, increase flexibility, and improve network performance.

2. Explain the difference between a router and a switch.

A router is a networking device that operates at the network layer (Layer 3) of the OSI model. It connects multiple networks together and forwards data packets based on IP addresses. A switch operates at the data link layer (Layer 2) and builds a MAC address table to forward data within a LAN.

3. What is the purpose of subnetting?

Subnetting allows you to divide a network into smaller subnetworks, known as subnets. It helps in efficient utilization of IP addresses, reduces network congestion, improves network performance, and enhances network security by logically separating different departments or segments.
