VLAN stands for Virtual Local Area Network, used to segment network traffic for improved security and performance.

VLANs divide a single physical network into multiple logical networks, improving network security by isolating traffic.
VLANs can improve network performance by reducing broadcast traffic and allowing for more efficient use of network resources.
VLANs can simplify network management by grouping devices based on function or department.
Example: VLAN 10 for finance department, VLAN 20 for marketing department.
VLANs can also enhance network scalability by allowing for easier expansion and reconfiguration.
