OK, great.
Now, in addition to the other networking devices that we have already seen, there are other specialized
devices which are really important in computer network.
Now you have to actively participate in moving the network data and these devices help pretty much while
you're transmitting data from one point to another point, when the fourth device that we're going to
see is multilayer switch, then they are going to talk about what is a load balancer now, multi-device
switch.
You know, what is multilabel switch?
I don't need to tell you.
Then it is DNS server.
You have all the domain name system.
Then proxy server, which we all use, were downloading different things than encryption devices, analog
modem packets, shipper, VPN concentrator, media converter and VIP and point VOIP is basically voice
over Internet protocol.
Now make sure that I'm not going to go into very detail of the scope then devices, but I'm just going
to give you an overview so that if anyone asks you, hey, please tell me what is a proxy, so you will
surely be able to answer all those questions.
So let us get started with the multilayer switch.
