Open Systems Interconnection (OSI) Essay

lab 2.1 get along 2.1.1All these elements are undeniable because each allows the other to function and do its job. Without Media the signal cannot transmit. Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without convening there would be no established format for the signals. And timing lets the devices exist when the pattern starts and ends.Exercise 2.1.2Almost all interlocks in use at present are based in some fashion on the yield Systems Interconnection (OSI) standard. The core of this standard is the OSI Reference Model, a set of heptad layers that define the different stages that data must go through to motivate from one device to another over a network. But the OSI is fair a guideline.Exercise 2.1.3The other networking services areRIP attendantSimple TCP/IP ServicesUPnP exploiter InterfaceExercise 2.1.4Wi-Fi wireless networks support ad hoc connections between devices. Ad hoc Wi- Fi networks are arrant(a) friend 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 outdoor(a) device that connects directly to a computer but does not break to the computers primary function. It helps access and use the functionalities of a computer. (ex. Mouse, trashy 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 few amount of connections the fast the connection speed with the current connections.3)A peer-to-peer (P2P) network is created when two or much PCs are connected and share resources without spill 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 shared by all the peers, unlike server-client architecture whe re Server shares all the contents and resources. 3) P2P is more reliable as central dependency is eliminated. Failure of one peer doesnt affect the functioning of other peers. In case of leaf node 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.
