‫So before talking about violence, I think it's better to give a brief summary of lands in general.
‫So, Alan is a local area network.
‫It's a group of computers and associated devices that share a common communications line or wireless
‫link to a server.
‫Typically, a LAN encompasses computers within a distinct geographic area, such as an office or a commercial
‫establishment.
‫Computers and other mobile devices use a LAN connection to share resources such as a printer or even
‫network storage.
‫A virtual local area network, virtual land, or Vlad, is a group of hosts with a common set of requirements
‫which communicate as if they were attached to the same broadcast domain, regardless of their physical
‫location.
‫So a villain has the same attribute as a physical local area network or LAN, but it allows for any
‫stations to be grouped together, even if not on the same network switch, right?
‫VLAN membership can be configured through software instead of physically relocating devices or connections.
‫The land is an important topic, and it should be included in this course.
‫But why did I put it in this section, the data link layer?
‫Yes, because the land is partitioned and isolated in a computer network at the data link layer.
‫Very good.
‫Let's get into that.
‫In this context, virtual refers to a physical object recreated and altered by additional logic.
‫Villains work by applying tags to network packets and handling these tags in networking systems, creating
‫the appearance and functionality of network traffic that is physically on a single network, but act
‫as if it is split between separate networks.
‫So let's let's run down some of the primary benefits of using violence.
‫So security at the top.
‫Groups that have sensitive data are separated from the rest of the network, separating systems that
‫have sensitive data from the rest of the network decreases the chances that people will gain access
‫to the information that they're not authorized to see.
‫Cost reduction.
‫Cost savings result from less need for expensive network upgrades and more efficient use of existing
‫bandwidth and uplinks.
‫Higher performance, careful monitoring of network use allows a network administrator to create villains
‫that reduce the number of router hops and increase the apparent bandwidth for network users.
‫Broadcast storm mitigation.
‫So dividing a network into villains reduces the number of devices that may participate in a broadcast
‫storm since a principal element of a villain is the fact that it does not pass broadcast traffic to
‫nodes that are not part of the villain.
‫It automatically reduces broadcast.
‫Improved it, staff efficiency.
‫That's right, VLANs, make it easier to manage the network.
‫When you provision a new switch, all the policies and procedures already configured for the particular
‫VLAN are implemented when the ports are assigned.
‫Simpler company management companies may want VLAN set up for departments that are heavy network users,
‫such as multimedia or engineering, or VLAN across departments that is dedicated to specific types of
‫employees, such as managers or salespeople.
