Introduction Virtual Local Area Network or VLAN is a logical local area network. VLAN extends beyond a single traditional LAN to a group of LAN segments. VLAN is unique because it is a logical entity‚ where configuration is done in software. This paper will explain the benefits of VLAN and how implementing VLAN would benefit any company. Benefits of Creating a VLAN As organizations grow in size‚ users‚ and departments‚ they must keep network activity and performance working effectively and

computers in Local Area Networking. Due to its small size‚ it is possible for one person to administrate a Local Area Network. Local Area Networks are viable to quick change‚ using a bus network topology that allows for easy access to the Local Area Network. Wireless Local Area Networks are much like LAN networks‚ except they do not require network cables to connect each other. Radio and infrared signals are used to communicate between machines whilst using a wireless local area network. Wireless

The operation is simple as collection of bridges in a local area network (LAN) can be depicted as a graph whose nodes are bridges and LAN segments (or cables)‚ and whose edges are the interfaces connecting the bridges to the segments. To break loops in the LAN while maintaining access to all LAN segments‚ the bridges collectively compute a spanning tree. The spanning tree is not necessarily a minimum cost spanning tree. A network administrator can reduce the cost of a spanning tree‚ if necessary
