What is Vlans and explain ?

Question

Accepted Answer

VLANs (Virtual Local Area Networks) are used to segment a single physical network into multiple virtual networks.

VLANs help improve network security by isolating traffic within specific groups.
They can also improve network performance by reducing broadcast traffic.
VLANs are configured at the switch level and allow devices in different VLANs to communicate as if they were on separate physical networks.
Each VLAN has its own broadcast domain.
Example: VLAN 10 for finance department, VLAN 20 for marketing department.

This is a method of physically device and logically convert multiple lan multiple broadcast the all data in network

Accepted Answer

Logical Segmentation: VLANs enable the creation of multiple virtual LANs within a single physical network infrastructure. Devices within the same VLAN can communicate with each other as if they were on the same physical LAN, regardless of their physical location.

Broadcast Isolation: By segregating devices into different VLANs, broadcast traffic is contained within each VLAN. This helps reduce network congestion and improves overall network performance by limiting the scope of broadcast storms and unnecessary traffic.

Security: VLANs provide a level of security by isolating sensitive or critical network resources. For example, separating guest Wi-Fi traffic from internal corporate traffic using different VLANs can prevent unauthorized access to internal resources.

Flexibility: VLANs allow network administrators to organize devices logically rather than physically. This flexibility enables easier management of network resources, facilitates changes and expansions, and simplifies network troubleshooting.

VLAN Tagging: VLANs are identified and distinguished using VLAN tags. When a device sends traffic on a VLAN-aware network, the traffic is tagged with a VLAN ID that corresponds to the VLAN to which the device belongs. Switches use these tags to forward traffic to the appropriate VLANs.

Inter-VLAN Routing: While VLANs segregate traffic within the same VLAN, devices in different VLANs cannot communicate directly without routing. Inter-VLAN routing involves the use of routers or Layer 3 switches to route traffic between VLANs, enabling communication between devices on different VLANs.
