In this task I will be using a diagram to outline the relationship between the layers in an interface showing each other of the points in the corresponding layer in the TCP/IP protocol suite. I will also be describing the type and functions of entities and the service they provide.
A)
The way communications are done between a computers on a network is through protocol suits. The most used protocol suite and commonly available protocol suite is TCP/IP protocol suite. A protocol suit contains a layered structural design where each layer represents some functionality which can be passed out by a protocol. Each layer usually contains more than one protocol options to carry out the duty that the layer follows to. TCP/IP usually has 4 layer system …show more content…
The application layer contains programs or processers that use transport layer protocols so that it delivers the data to the destination of the computers. The application layer has many protocols that programs use to communicate with the second layer which is called Transport layer. Some of the application layer protocols are: Simple mail transfer protocol (SMTP), File transfer protocol (FTP), Hypertext transfer protocol (HTTP) and Simple network management protocol (SNMP).
Transport layer
The second layer of TCP/IP protocol suite is the transport layer. The transport layer delivers backbone to data flow between two hosts. The transport layer receives data from the application layer which is the first layer in TCP/IP protocol suite. In the transport layer there is a lot of protocols that work in there but there is two protocols that gets frequently used and these are TCP (Transmission control protocol) and UDP (User datagram protocol).
Internet layer
The third layer of TCP/IP protocol suite is the internet layer. The purpose of the internet layer is to organise or handle the movement of data on network. The meaning of movement of data is routing of data over the network. The main protocol used in the internet layer is IP (internet protocol), however ICMP (Internet control message protocol) and IGMP (Internet group management protocol) are also used in the internet
