	INTERNET PROTOCOL TCP/IP How information is sent through the internet. TCP (transmission control protocol) means cutting up many copies of the webpage into packets and sending them through various channels within the internet, all eventually going to you. IP (internet protocol) is the 12 digit address (like 142.109.265.155) that every computer on the internet has a unique one of. This address is placed on each packet so they will find your computer. Hyper Text Transfer Protocol (http) It means pages automatically load (automatically saved in cache instead of asking you where you want to save it). Original use of http was to give people a way to publish and retrieve hypertext pages within the Internet. File Transfer Protocol ( ftp) File Transfer Protocol is used to transfer files over a network to other computers. The difference from http is that you indicate where you want to save the files to (or upload them from). Files offered cover nearly anything that can be stored in a computer. For example, photos, gaming, music and statistics. HARDWARE: Topologies bus All nodes are connected to a single wire or cable (the bus) which has two endpoints. Each communications device on the network transmits electronic messages to other devices. If some of those messages collide, the sending device will wait and then try to transmit again. The advantage of bus network is that it is can be organized as a peer-to-peer network or client/server network. It is also relatively inexpensive to install. The disadvantage is that if the bus network fails, the whole system network fails. The wider the bus the better! ring The ring network is a network in which all communications devices and microprocessors are connected in a continuous loop. Electronic messages pass around the ring until they reach the correct destination; there is no central server. The advantage of a ring network is that messages only flow in one direction. The disadvantage is that if a single connection is broken, the whole network stops working. The distributed star or tree topology can provide many of the advantages of the bus and the star topologies. It connects workstations to a central point, called a hub. This hub can support several workstations or hubs which, in turn, can support other workstations. Distributed star topologies can be easily adapted to the physical arrangement of the facility site. (Integrated Publishing) star A network that links all microcomputer and other communication devices through a central server. The advantages of this hub is that it prevents impact between messages. The network forms a star shape having the central server in the middle with a single branch outward, the branch will not branch to another device. Other Advantages Include: * Good performance. * Scalable, Easy to set up and to expand. * Any non-centralised failure will have very little effect on the network, whereas on a ring network it would all fail with one fault. * Easy to detect faults * Data Packets are sent quickly as they do not have to travel through any unnecessary nodes. * It is used for centralised control.
