'Open Systems Interconnection (OSI) Essay\r'

'Lab 2.1\r\n operation 2.1.1\r\nAll these elements be necessary beca physical exercise each anyows the new(prenominal) to function and do its job. Without Media the signal cannot transmit. Without Interface the figurer cannot main course the Media. Without the signal the electricity or strapper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the turns know when the simulate starts and ends.\r\nExercise 2.1.2\r\nAlmost all ne 2rks in use today are based in both(prenominal) fashion on the Open Systems Inter connector (OSI) standard. The philia of this standard is the OSI Reference Model, a set of cardinal layers that define the different stages that data must go through to travel from one device to some other over a network. But the OSI is just a guideline.\r\nExercise 2.1.3\r\nThe other networking services are:\r\n economic rent Listener\r\nSimple TCP/IP work\r\nUPnP exploiter Interface\r\nExercise 2. 1.4\r\nWi-Fi wireless networks survive ad hoc connections between devices. Ad hoc Wi-Fi networks are dainty peer to peer compared to those utilizing wireless routers as an middling device.\r\nExercise 2.1.5\r\nLab 2.1 Review\r\n1)\r\nA computer peripheral device is an internal or external device that connects directly to a computer but does not contribute to the computer’s primary function. It helps access and use the functionalities of a computer. (ex. Mouse, flash drive, printer) Network devices are components used to connect computers or other electronic devices together so that they can deal out files or resources. (ex. Router, dsl filter, Ethernet cable)\r\n2)\r\nThe fewer amount of connections the fast the connection speed with the current connections.\r\n3)\r\nA peer-to-peer (P2P) network is created when two or more PCs are connected and share resources without going through a separate emcee computer. Benefits:\r\n1) It is easy to install and so is the configurat ion of computers on this network. 2) All the resources and contents are shared by all the peers, unlike server-client architecture where Server shares all the contents and resources. 3) P2P is more reliable as primaeval dependency is eliminated. Failure of one peer doesn’t affect the functioning of other peers. In lesson of Client â€Server network, if server goes down whole network gets affected. 4) There is no need for regular System Administrator. Every user is the administrator of his machine. User can control their shared resources.\r\n'
