Ethernet The 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

technology used to make local area network to support data communication by connecting terminals, computers and printers within a small limited geographical area. Examples of LAN Technology include; Token Ring, Fibre Distributed Data Interface (FDDI) and ARCNET. Local Area Network is a data communication network connecting Terminals, Computers and Printers within a building or other geographically limited area. These devices can be connected through wired cables or wireless link. It is also

Topologies and Network Technology NTC/361 Monday, August 8, 2011 Thomas Krawczyk Topologies and network technology In every project, it is important to have a goal, and that goal should be the foundation on which a project team spring into action. The foundation should involve an infrastructural plan, and the usability of the components of the infrastructure. A project plan, as in any other plan, should outline the premise of the project and answer some basic questions like why

Bus Topology is used for small and simple networks. Bus topology connects all computers in a linear shape with a backbone to connect all computers. A single cable is used to connect all computers devices with interface connector. A single device send message towards other devices attached with it but only intentional recipient accept and process the message. A central device like hub, router and switch is used to connect all computers in Star Topology. The functionality of connected devices is entirely

Networking Networking There are many different types of topologies and this paper will discuss many advantages and disadvantages of them. Bus Topology In a bus topology, all the network devices are in a linear shape which acts as a common backbone. There is a single cable which functions as the go between for the devices that are attached to this connector. The device will send the messages to all of the devices attached to this shared cable. However, only the intended device will receive and

Networking Jennifer Otten Mohammad Kazmi NTC/361 May 21, 2012 Bus Topology In networking the bus topology is that one computer at a time can send information. This affects the performance of the network. There are limited amounts of computers attached to this network. All users share the amount of transmission time. For each computer that is sending data the longer some computers wait to send their data (Tomosho, Tittel, & Johnson, 2004). The bus topology is a passive topology, which

Network Topologies are in essence the way the network is laid out as it relates to the devices that are connected to it. If you could view all the devices connected to the network, the arrangement would suggest which type the network topology it falls within. The topologies can be described as either a physical or logical design in their defined layout. Network topologies are grouped in the following design categories, Mesh, Bus, Ring and Star Topologies. A mesh topology comes in two varieties

LAN, MAN and WAN Student Name University Network Telecommunication Professor Name October 21, 2013 LAN, MAN and WAN Computer networking is simply the communication between two or more computers that allow them to share information and hardware resources. This is really one of the most important contributions to the information age since personal computers were invented. The connection and communication of just two computers exchanging data and devices is the most fundamental
