What is a VLAN? A Virtual Local Area Network (VLAN) is a custom network created from one or more existing LANs. It allows devices on different LAN segments to communicate as if they were on the same physical segment, regardless of their geographical locations. VLANs are used to segment network traffic, enhance security, and improve the efficiency of network management. Why are VLANs Important? Improved Security: VLANs provide an added layer of security by segregating sensitive data and reducing the risk of breaches. Unauthorized users can be kept off VLANs where they don't belong. Enhanced Performance: By isolating network traffic, VLANs reduce broadcast domains, decreasing the amount of unnecessary traffic and improving network performance. Simplified Network Management: VLANs make it easier to manage and configure networks, allowing for more efficient troubleshooting and maintenance. Better Utilization of Resources: VLANs enable logical grouping of devices, which can help optimize the use of available resources and simplify the deployment of new services
