So before talking about violence, I think it's better to give a brief summary of lands in general.
So Len 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 land connection to share resources such as a printer or even
network storage.
A virtual local area network, Virtual Land, or Vladi, 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 attributes as a physical local area network or LAN, but it allows for end
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.
Vlad is an important topic, and it should be included in this course, but why did I put it in this
section, the datalink layer?
Yes, because the land is partitioned and isolated in a computer network at the datalink layer.
Very good.
Let's get into that.
In this context, Virtual refers to a physical object recreated and altered by additional logic.
Villans 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 jobs 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 principle element of a villain is the fact that it does
not pass broadcast traffic to nodes that are not part of the VLAN, it automatically reduces broadcasts.
Improved it staff efficiency.
That's right, villans 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 out 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.
