Open Systems Interconnection (OSI) Essay Example for Free

pioneer Systems Interconnection (OSI) EssayLab 2.1 get along 2.1.1All these elements be necessary because each allows the early(a) to snuff it and do its job. Without Media the signal pratnot contain. Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the devices know when the pattern starts and ends. make 2.1.2Almost all networks in use today are based in some mood on the Open Systems Interconnection (OSI) standard. The core of this standard is the OSI Reference Model, a set of seven layers that pose the different stages that data must go through to travel from one device to another all over a network. But the OSI is just a guideline.Exercise 2.1.3The other networking services areRIP hearerSimple TCP/IP ServicesUPnP User InterfaceExercise 2.1.4Wi-Fi wireless networks support ad hoc connections betwee n devices. Ad hoc Wi-Fi networks are pure peer to peer compared to those utilizing wireless routers as an intermediate device.Exercise 2.1.5Lab 2.1 Review1)A peripheral device is an internal or external device that connects like a shot to a computer but does not contribute to the computers primary function. It helps access and use the functionalities of a computer. (ex. Mouse, heartbeat drive, printer) Network devices are components used to connect computers or other electronic devices together so that they can share files or resources. (ex. Router, dsl filter, Ethernet cable)2)The fewer amount of connections the fast the connection speed with the current connections.3)A peer-to-peer (P2P) network is created when two or more PCs are connected and share resources without going through a separate server computer. Benefits1) It is easy to install and so is the configuration of computers on this network. 2) All the resources and contents are overlap by all the peers, unlike server-cl ient architecture where Server shares all the contents and resources. 3) P2P is more secure as central dependency is eliminated. Failure of one peer doesnt affect the functioning of other peers. In case of Client Server network, if server goes down whole network gets affected. 4) There is no need for full-time System Administrator. Every user is the administrator of his machine. User can control their shared resources.
