Ethernet protocol is by far the most widely used. Ethernet uses an access method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection). This is a system where each computer listens to the cable before sending anything through the network. If the network is clear, the computer will transmit. If some other node is already transmitting on the cable, the computer will wait and try again when the line is clear. Sometimes, two computers attempt to transmit at the same instant. When this happens

LAN Topologies IT240 10/14/12 1. Case Project 2-1 With a network of 50 computers I will use the Ring Topology to upgrade this network. With this type of topology all the devices are connecting in a loop form and the information travels in one direction, thus avoiding collisions. Here the cabling doesn’t terminate, it continually goes from one device to another till it gets back to the original device. It is also easier to manage the network since all the information is passed around

Integrative Network Design Project Part 1 NTC/362 May 5, 2014 Fernando Casafranca Integrative Network Design Project The Patton-Fuller Community Hospital looks to upgrade their Information Technology (IT) capability beginning with their networks. The characteristics, components, and topology are evaluated to properly identify the needs for the new network design. The plan includes converting to a Wireless Local Area Network (WLAN), installing a Voice over Internet Protocol

Lesson 4 Review: LAN Topologies The purpose of this activity is to reinforce what you have learned so far about local area networks technologies. What are the two methods that Carrier Sense Multiple Access (CSMA) employs to handle messages that are sent simultaneously? (Min. word count: 15) Carrier sense multiple access methods are detection where a transmission is cancel when collision is detected and avoidance where transmission is delayed. Which topology would you use when unable

Information processing; Network Topologies Network topology is the arrangement of various elements (links, nodes etc). It is essentially the topological structure of a network and can be depicted physically or logically. Physical topology being the configuration of cables, computers and other peripherals whilst logical topology illustrates how data flows within a network regardless of its physical design. Types of network topologies include bus, star, mesh and ring topologies. Bus networks use a common backbone

Integrative Network Design Project Shaquita Boss NTCC/362 October 19, 2015 Peter Fortuna Kudler Fine Foods Kudler Fine Foods was established in 1998 from a vision of a very motivated and passionate gourmet cook by the name of Kathy Kudler. The vision came about when the frustration of having to travel around town to gather ingredients for what she thought was an untroublesome dinner. Kathy then decided to establish her very own gourmet food shop. The first store was opened in La Jolla, California
