Let's talk about PXP relationship.
This is the collection establishment of D.C. protocol and Pakistan transmission control protocol.
We have some control the transmitting the data.
And we need to establish the connection from the source to this nation before sending any package.
So this is done in a previous event, one communication in a three way handshake.
So first, the source wants to communicate with the nation quietly, simple protocol.
It sends that network packet with the seal flagging it.
So the transport these are generally data being sent is called packets are from network layer and up
to application.
These are generally called packets.
And in the gathering they're called frames.
And it's physical.
It is with but in general, we call it as a package too, because we just deal with the other applications.
So a source will send the packet with synchronize flag on one of these Frex containing some special
purposes and in which one of it is synchronized if this is on.
So we are sending that connection initiation with a packet.
Packaged with the flag, one simple, like you said, so often unseen this package.
This nation understands that someone is going to are wanting to connect to me.
So if the nation wants to accept this connection, it will send simplistic, packaged simplicity.
So interesting, Grace and I for technology.
So this packet number will be the sum total and that synchronise is said to someone and then a card
along with synchronises.
The acknowledgement is also said one, and that packet is sent from this nation to source.
So the source on the simplicity of the destination also wants to connect to me.
So my connection is successful and it was an acknowledgement package.
So this is an acknowledgement and the destination on seeing this acknowledgement packet, understanding
itself that my simplistic package has been reached to the source and it has been seen by the source.
And from then on, what I got that acknowledgement from the source, that means from this part, I can
just send the data to and for to input from the source.
So, OK, this is not trivial.
Let me explain again.
First source wants to connect to the destination.
That's why it sends a packet with Syrian flag one single flag one and then destination on seeing this
flag.
If it wants to connect to the source, then it was in the same place at Flag Zone.
And the source on seeing this implicit acknowledgement, it will understand that this station is also
ready to accept the connection.
That's why it was an acknowledgement packet.
And on seeing the nation, OK, so it's got my signature, an acknowledgement packet.
From here onwards, we can transfer the data.
So this is a three way handshake.
And if you use it for communication establishment.
No, let's talk about the connection termination.
So up to now, Suzanne, this nation has transferred the data and its source want to disconnect from
the destination.
So since the packet with the flag are finished and sort of finished.
So I want to finish the connection.
And on seeing this destination, OK, it understands that source want to disconnect from me.
So to send the acknowledgement packet.
So on seeing this acknowledgement packet source, wait for another packet with a Finnish flag.
So this notion also sends the Finnish flag to the source.
So on seeing these two packets with acknowledgement and finish.
OK, I also got your finished packet.
Now let me send the acknowledgement packet so that from here on what we will, we are no longer friends
and we long we no longer communicate each other.
So this is the TV connection television source will send the footage back to the destination.
Because source wants to disconnect with the National Trust, the initial computer, and then answer
in this packet, the acknowledgement faggoty and also nothing packetized, because this acknowledgement
is to reply to this finished packet.
And this nation also wants to disconnect with the source.
That's why it also sends the Finnish packet and this nation gets refused to back it from the source
saying that I got the finished product from you.
OK, we no longer have the connection.
So this is our DCP connection.
Termination.
I hope you have understood.
