Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are

WAN Design Today’s network administrators must manage complex wide-area networks (WANs) in order to support the growing number of software applications that are built around Internet Protocol (IP) and the Web. These WANs place a great demand on network resources‚ and require high-performance networking technologies. WANs are complex environments that incorporate multiple media‚ multiple protocols‚ and inter-connection to other networks‚ such as the Internet. Growth and manageability of these network

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed
