VLAN or virtual LAN refers to the part of a computer that is found in one of the layers. It is also known as the local area network. It is located in the data link layer, which is the OSI layer 2 of the computer network. This has many vital uses on the computer. It provides security in your computer as well as conducting traffic in your computer and computer system.
