1.1.2. Protocol Hierarchy
The communication between the computers in the Internet is defined by
different protocols. The protocols TCP (Transmission Control Protocol) and IP
(Internet Protocol) build the basis of the communication in the Internet. The
combination of the TCP and the IP protocol is known as TCP/IP protocol that
represents the standard system used in most large networks.
Before describing these and some other protocols, it will be helpful to
illustrate the position of each protocol relative to the others in the protocol
hierarchy.
By moving the mouse cursor over the abbreviations in the boxes you can see the whole name of the protocol.
Protocol Hierarchy. Modified according to (BADACH et al. 2003)In the next paragraphs we will go into details of some protocols. To understand better the function of the different protocols and their differences we explain you the theory using an example: We will show you how a computer sends the textfile "textfile.txt" to another computer like it is illustrated in the following graphic.
