Lan Topologies

LAN Topologies IT240 10/14/12 1. consequence Project 2-1 With a network of 50 computers I will physical exertion the family Topology to upgrade this network. With this type of topology altogether the devices are connecting in a loop invent and the information travels in star direction, thus avoiding collisions. Here the cabling doesnt terminate, it continually goes from one device to other till it gets plump for to the original device. It is also easier to manage the network since all the information is passed around the mobilise in the same direction. . Case find out 2-2 With that many computer and four servers, I will procedure an broad Star Topology. As pointed out in the case project that on that point are a few switches available here, I will use a central switch and connect the rest of the available switches to it and connect the 200 PCs to those switches. Switches are good for determining each(prenominal) individual packets destination and ensuring that they are delivered to the right device.Note crimson though they might have two different uses in roughly cases, the hubs in my diagram represent the switches. 3. Case project 2-3 * Physical versus crystalline topology A physical topology defines how the devices on a detail network are physically connected logical on the phone line tells us how the systems on the physical topology communicate. * Bus Topology In this topology all the devices are physical chained to one some other through a single cabling system.This form of topology works disclose when the numbers of computers on the network are limited. * Star Topology This is the form of topology where all devices connect to central unit through a hub, switch or even a router. One of the biggest advantages here is in the event one of the devises failed, it does not bring the entire network down. * Ring Topology In this form of topology all the devices are instantaneously connected to the next existing device in a ring form.This kind of works like the bus topology, however, there is no decease here, as the devices connect from one to another all the way back to the original device. * Ethernet and CSMA/CD This is the type of technology networks use to sense if there is an ongoing transmission. In the event where there is one, the system goes into wait musical mode till the channel is free for it to begin its own transmission. This is one of the ship canal to avoid collision.
