Mesh‚ Bus‚ Ring and Star topologies Mesh A mesh topology typically refers to a Wide Area Network where there are multiple paths connecting multiple sites. A router is used to search multiple paths and determine the best path for the data. Routes are determined by least cost‚ time of day and performance. A three or four site mesh network is relatively easy to create‚ whereas it is impractical to set up a mesh network of 100 sites or nodes. Mesh networks are used in Wide Area Networks (WANs) where

------------------------------------------------- Network topology Network topology is the arrangement of the various elements (links‚ nodes‚ etc.) of a computer or biological network. Essentially‚ it is the topological structure of a network‚ and may be depicted physically or logically. Physical topology refers to the placement of the network’s various components‚ including device location and cable installation‚ while logical topology shows how data flows within a network‚ regardless of its physical design. Distances between nodes‚ physical

A mesh network is a network topology in which each node (called a mesh node) relays data for the network. All nodes cooperate in the distribution of data in the network. A mesh network can be designed using a flooding technique or a routing technique. When using a routing technique‚ the message is propagated along a path‚ by hopping from node to node until the destination is reached. To ensure all its paths’ availability‚ a routing network must allow for continuous connections and reconfiguration

Bus Topology http://compnetworking.about.com/od/networkdesign/a/topologies.htm http://fallsconnect.com/topology.htm Bus topology Bus topology refers to a single cable that connects all the workstations‚ servers‚ printers and other devices on the network. The cable runs from device to device by using tee connectors that plug into the network adapter cards. Each end device has a terminator on one end of the tee and a cable going out to the next device on the other end‚ while all devices in the

What is Mesh Topology? In a mesh network topology‚ each of the network node‚ computer and other devices‚ are interconnected with one another. Every node not only sends its own signals but also relays data from other nodes. In fact a true mesh topology is the one where every node is connected to every other node in the network. This type of topology is very expensive as there are many redundant connections‚ thus it is not mostly used in computer networks. It is commonly used in wireless networks

BUS TOPOLOGY REMAINS THE MOST USED Bus topology is the physical and logical design of a bus network. All the nodes (devices) on a bus network have to share access to the network to communicate. The nodes can only transmit data one device at a time. A bus is the central cable‚ the main wire that connects all devices on a LAN (Local Area Network). Bus topology is known as the simplest network topology‚ and also known as a linear bus (Oliviero and Woodward‚ 2009‚ p. 104). Bus topology is the

Star and extended star topologies The star topology is the most commonly used physical technology in Ethernets LANS‚ when installed ‚ the star topology resembles spokes I n a bicycle wheel. The star topology is made up of a central connection point that is a device such as a hub‚ switch‚ or router‚ where all the cabling segments meet. Each host in the network is connected to the central devices (switches) with its own cables (we are using Fiber Optic Cable) although a physical star topology costs

In The Hobbit‚ Gollum has a short part in the story. In the cave‚ Bilbo discovers a ring that lets him do many things. If the ring were to be taken out of the equation‚ there would still be a purpose for introducing the character‚ Gollum. Introducing the ring‚ and Gollum does make a difference in the story. This part of the story shows Bilbo being confident‚ risky‚ and heroic. When Bilbo first enters the dark cave and meets Gollum‚ they play a riddle game. At the end of the game‚ Bilbo asks Gollum
