What is vlan and describeit

Question

Accepted Answer

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

VLANs divide a physical network into multiple logical networks, allowing for better control over traffic flow.
Each VLAN operates as if it is its own separate network, even though devices may physically be connected to the same network switch.
VLANs can improve network security by isolating sensitive data or systems from other parts of the network.
VLANs can also improve network performance by reducing broadcast traffic and segmenting traffic based on specific criteria.
For example, a company may have separate VLANs for different departments like finance, marketing, and IT to keep their traffic separate.
