What Is VLAN?
VLAN, is an acronym for Virtual Local Area Network.  To understand what a VLAN purpose you must first understand what a local area network is.  A local area network consist of network devices such as switches, hubs, bridges, workstation, and servers.  All are connected together using a network protocol to communicate to each other. 

Common Types Of Network Protocols

	Ethernet (The Ethernet protocol is by far the most widely used one)
	Fast Ethernet (To allow for an increased speed of transmission, the Ethernet protocol has developed a new standard that supports 100 Mbps.)
	Local Talk (Local Talk is a network protocol that was developed by Apple Computer, Inc. for Macintosh computers.)
	Token Ring (The Token Ring protocol was developed by IBM in the mid-1980s. The access method used involves token-passing.)
	FDDI (Fiber Distributed Data Interface (FDDI) is a network protocol that is used primarily to interconnect two or more local area networks, often over large distances.)
	ATM (Asynchronous Transfer Mode (ATM) is a network protocol that transmits data at a speed of 155 Mbps and higher)

What Is The Purpose Of A VLAN
A VLAN is similar to a local area network.  It is a group of workstations, servers, and network devices that appear to be on the same network despite their location but are not able to access those network resources.  As they are no longer on the same network but are on a different network resulting in those resource being isolating from specific groups of computer and devices.  All without the need of addition network devices such as a switch.  It allows you to separate a single network into a multitude of networks without the need of additional equipment.

How Does It Benefit Me?
A VLAN allows several networks to work virtually as an LAN.  One of the most beneficial elements of a VLAN is that it removes latency in the network, which saves network resources and increases network efficiency. In addition, VLANs are created to provide segmentation and assist in issues like security, network management and scalability. Traffic patterns can also easily be controlled by using VLANs

	Network Security (isolation of other computer and devices from other network resources), such as security systems.
	The ability to bridge only specific network traffic to be directed to those resources.
	The ability to save money in having to purchase addition network devices
	Increase bandwidth efficiency.

**Note: VLAN requires a higher level of network switch that supports (functionality & implementation) of VLAN.This type of class. The purpose of implementing a VLAN is to improve the performance of a network or apply appropriate security features.

CCC - Service Time
An average time is between an 60 to 90 minutes. It will depend on the amount of equipment to move and time needed to reconnect all the components.
