Transmission Control Protocol or Internet Protocol - TCP / IP is a communication protocol that was developed to support different internetwork . It was invented by Bob Kahn and Vinton Cerf who developed standard protocol for Unix . It contributed to introduction of Internet and formed the standard for wide area networks and local area networks It was able to lay the foundation of the current Internet through its former ARPANET , which was the first wide area internet

TCP / IP contain a suite

, which is called TCP /IP suite that contains and defines various rules , which computers in a network uses to communicate Hence , TCP /IP contains strategies on how data should be addressed formatted , routed , shipped and delivered to the required destination There are different protocols for each communication type and contains a base line , which address a more detailed type of connectivity . TCP /IP contains four layers or abstractions that enable it to communicate easily

Architecture

Generally , TCP IP suite is a group of protocols that are used in supporting data communications between computer peripherals and LANs and internetworks . It forms the basis of the protocol that is used in the Internet . This name comes from the important protocols that are employed : Internet Protocol (IP ) and Transmission Control Protocol (TCP . The TCP /IP protocol is common because of

Software and hardware independence

Large and flexible addressing method

Presence of available standards

TCP /IP Model Layers

Different layers in the model are situated differently , the layers that are at the top are usually closer to user application while the lower layers are closer to physical transmission . The layers provide different services depending on their position . This means that the top layers can decide not to corporate with the lower layers . Therefore , TCP /IP have the capacity of providing delivery guarantee and at the same time integrity . There are usually four layers , which include the Link Layer Internet layer , Transportation layer and Application layer (Philemon 2005 , pp . 71 - 74

Data Link Layer or Network Access Layer

This is the lowest level of a TCP /IP protocol group . This part is usually not seen because of presence of middle and upper protocols . Some of the middle protocols , which hide the network layer , are the TCP , IP and UDP while the upper or higher levels are the HTTP , SMTP and the FTP Some functions that occur in the network layer are encapsulation of the IP datagram into frames so that it can be transmitted by network , and also mapping any IP address to the physical hardware addresses (Macklin 2007 , pp . 47 - 48

Drivers and software applications make most of these operations successful , which are unique to each type of hardware . Configuration at this level is only through selecting the right driver and using the TCP /IP as the protocol to be used . Most companies that manufacture different computers preload such information and others are supported by the plug and play applications

However , certain network...
