Hello students, in ip stack there are 5 layers are there.
00:08
One is the physical layer.
00:21
In this physical layer we get that cables and connectors are used as physical layer.
00:35
This physical layer is connected to the data link layer.
00:43
All the cables are designed with specific radius and specific lengths.
00:49
There will be a data transfer from the cable and connectors.
00:56
These cables are end to end connected.
00:59
The data transfer between adjacent network devices.
01:22
It is used to transfer the data from the adjacent network devices.
01:27
The data link is connected by the cables from end to end.
01:32
The third layer is the network layer.
01:41
In this network layer we can see that there is a forwarding of data.
01:49
Forwarding of data and routing also the address data.
02:04
Routing the address data.
02:10
The data is addressed or forwarded from the network layer by the data link through the cables.
02:19
The fourth layer is the transport layer...
