Question

Select one of the objectives below, do some additional research on the topic. Then write a two or three paragraph post expanding on the topic.

Objectives:

• the need for a transport layer

• Transmission Control Protocol (TCP), the popular transport layer protocol

• TCP functions, including segmentation, reliability, flow control, multiplexing, and connection establishment

• the fields of the TCP header

• UDP, a simpler protocol at the transport layer

Answer 1

I have picked second objective Transmission Control Protocol (TCP) :

It is used to provide a network connection between the applications.It works with Internet Protocol(IP) to send/receive messages through a network.It is connection-oriented protocol.That is the connection between sender and receiver will be kept alive till all the processing of the data is done.

It is more secured way of transmitting the data.the most important process of TCP incudes , it knows how to divide the data into several chunk packets , That deliver to network packet.

It also takes care of following functions:

i)delivers Error-free messages

ii) flow control

iii)Packet transmission

The TCP protocol is very secure way of delivering packets. As we know it divides the messages into several segments which are called packets , it also takes care of those delivery to the mentioned destination by use of ip address in the header.

TCP also takes care of flow control of the packets.As we have already mentioned , It is connection oriented protocol , that means it will be having all acknowledgements of the sending and receiving end points information.If something goes wrong , it will immediately reports the error to the sender.
