In this module, we are going to discuss the communication earlier in the day, so there are two models
for the communication.
The first one is the same, a model.
That is open system interconnect model it, you just have a little model, and the second one is the
DCP IP, that is transmission control protocol and Internet protocol.
It is a five layer model.
So let's start with this model.
So we can see here, this is the way, as I said earlier, model, it consists of physical layer, datalink
layer, network, layer, transport, layer chandelier presentation and application layer.
While in the case of TCP IP protocol, we have a physical link, data link, network link and TCAP and
application.
So all these links are much with each other.
First, we start with the fiscal cliff.
So the fiscal year since individual goods for one communication system directly to the another communication
system.
So basically here the transmission is in the form of goods and it consists of media signal, binary
transmission and network interface cards.
So basically the physical system, which consists of the hardware part and in the transmission happens
in the form of which the second layer is the data clear.
So it enables data exchange between two or more directly connected devices.
It may be switches or physical addressing and the data transmission occurs in the form of frames that
thirdly return network layer.
So this layer provides a network layer Picart movement from one host to another host, and it also determine
the best path for sync or source, as well as logical addressing function.
So the transmission happened in the form of packet.
The next layer is the transport layer.
Here, Truss Transmission performs in segment and provides end to end connection and a reliable data
transmission.
So this is the responsibility of this year, the next layer, the situation layer.
So to control the connection between the multiple computers and initiate a session along with another
session.
So again, the transmission in the form of data.
So it ensures the establishment of a session between the two systems.
That next layer is the presentation layer.
It does it translate data between the application layer and network forward.
It is responsible for integrating all formats into a standard format for effective and efficient communication.
Moreover, it is possible for encryption, decryption, data compression, orographic handling.
The next layer is the application layer.
It provides interface to the user with the data from the communications system, and it includes network
access to the application, like web browser, email clients and streaming media interface.
So these are the prominent player in the communication system.
So basically there are two models.
One is that was a similar model and one is the top five layer model.
So in summary, in this topic we have discussed about the communication layers and in the next model,
we are going to learn about the software for the software defined radio.
