Networking Week 1

1.) State whether the following meshing descriptions be describing a MAN, WAN, or LAN? A.) LAN B.) MAN C.) Wan 3.) Expand the acronym NIC. cyberspace Interface card 5.) Expand the acronym WAN. radio set opening Network 7.) Define the terminus network topology. Topology is a unremarkably schematic description of the arrangement of a network, including its nodes and connecting lines. in that respect atomic number 18 two ways of define network geometry: the physical topology and the logical (or signal) topology. 9.) A wrong of the emblem-ring system is that if an error changes the tokens pattern it burn down ca intake the token to stop circulating. 11.) What is the difference betwixt a Hub and a heterotaxy? 13.) What data is not include in an Ethernet frame? The term hub is sometimes used to mention to any theatrical occasion of network equipment that connects PCs together, further it actually refers to a multi-port repeater. T his type of whatchamacallit simply passes on (repeats) all the information it go throughs, so that all devices connected to its ports receive that information. Hubs repeat everything they receive and can be used to extend the network. However, this can top in a lot of unnecessary handicraft organism sustain to all devices on the network. Hubs pass on traffic to the network admirationless of the intended destination; the PCs to which the megabuckss be sent use the do by information in each sheaf to work out which packets are meant for them. In a unclouded network repeating is not a problem only if for a larger, more heavily used network, another found of networking equipment (such as a switch) may be required to lick reduce the amount of unnecessary traffic being generated. Switches stick up the flow of network traffic based on the cite information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives) , and then forwards on packets to the put ! up port only. This allows simultaneous communication across the switch, improving bandwidth....If you regard to get a full essay, order it on our website: BestEssayCheap.com
