When the data and certain communication is transferred among the networks and computers there obtain certain rules, and formats of receive and sending the data in a fashion mode. And around the globe the most commonly and widely used protocol suite is the IP/TCP. And knowing the work and important of TCP/IP plays a major role for the transfer of data transmission in the network environments.
It is a fundamental concept in the TCP/IP architecture of the way the IP delivers a packet of data through a network which was mostly used in the large networks. And to understand the TCP/IP suit of protocols in the function overall the IP is main central part.
The Transport Layer:
The transport is mainly resided in between the transport layer and the network layer which is layer 4 and it was mainly in the core of the TCP/IP of the network architecture. It has a very important critical role of providing the communication in between the hosts and the application process. And knowing the work and procedure of the transport layer means of knowing the data transmission in the TCP/IP network systems.
The data from the application is replaced by the transport layer by placing a header on it. And the main function of this protocol was to identify the application and to which the data is received and to the internet layer to be passed down to the certain segments. Two additional functions also be perform in the transport layer they are reliability (which are provided by the acknowledgements and numbers) and flow control (these are provided by sliding windows). Flow control is a sort of applications to which connects and enables the hosts to know the communicating mechanism and to count the data in which transmits each time. And other Reliability used to mechanism of the guarantee the packet to be delivered.
In the transport layer there are two type of protocols:
· UDP: It is a protocol of unacknowledged and connectionless. And in these it is the responsible of transmitting the messages, and there are no certain checking for the segment delivery at this layer. It mainly depends upon the upper layer protocol for the reliability.
· TCP: It is a reliable protocol, connection-oriented. A connection been oriented in between the two ends of the systems before the data is begin to transfer among them. TCP plays a major role in breaking of the signals and the messages into various sort of segments, and at destination centre they are used to reassemble them, and the data is resent to the host where they receive anything and the messages are reassembled. In between the end users applications TCP used to supply virtual circuit among them.
Two devices are connected there will be a communication among them and the data and messages are passed through them. And to understand and give response to this messages devices are acted on this messages they should agree and rely on the messages exchange and certain action was requires to respond the message.
