STRATEGIC NETWORK OPERATION :: essays research papers

Anyone whos run a engagement operations group knows the thwarting that accompaniesmanagement inquiries about our network st pointgy. To be successful, a strategicnetwork plan must define the services the network will contribute the line operations of thebusiness.Network, in computer science, techniques, physical connections, and computerprograms employ to link two or more computers. Network users are satisfactory to share files,printers, and early(a) resources send electronic messages and run programs on othercomputers. A network has three layers of components application packet, networksoftware, and network hardware. diligence software consists of computer programsthat interface with network users and permit the sharing of breeding, much(prenominal) as files,graphics, and video, and resources, such as printers and disks.Network software consists of computer programs that testify protocols, orrules, for computers to talk to one another. These protocols are carried out by sendand receiving formatted instructions of data called packets. Protocols make logicalconnections between network applications, withdraw the movement of packets through thephysical network, and minimize the possibility of collisions between packets displace at thesame time. These are some of the distinguishable types of Network software Appletalk,Arpanet, Bitnet, CWIS, Ethernet, IBM Token Ring netwrok, Internet, LAN, andUSENET. Also Class A, B, & C network bushel to the different types of subnet protocol. Local Area Networks(LANs), which connect computers separated by scam distances,such as in an office or a university campus, unremarkably use bus, star, or ring topologies.Wide area networks (WANs), which connect aloof equipment across the country orinternationally, often use special lease telephone lines as point-to-point links, and is thebiggest network.When computers share physical connections to transmit information packets, a setof Media Access Control (MAC) protocols are used to allow information to flowsmoothly through the network. An efficient MAC protocol ensures that the infectionmedium is not idle if computers have information to transmit. It also prevents collisions payable to simultaneous transmission that would waste media capacity. MAC protocols alsoallow different computers fair access to the medium.One type of MAC is Ethernet, which is used by bus or star network topologies. AnEthernet-linked computer first checks if the divided up medium is in use. If not, thecomputer transmits. Since two computers can both find an idle medium and sendpackets at the same time, transmitting computers touch to monitor the sharedconnection and stop transmitting information if a collision occurs. Ethernet can transmitinformation at a rate of 10 Mbps.The most significant - and successful - encroachment occurred when switchedEthernet devices appeared on the scene.
