Case Study: Network Topologies Research You have been asked to help upgrade the LAN at a very successful ABC firm with five departments in one building and a total of 560 employees. Although the firm’s employees understand accounting‚ they haven’t spent much time improving their network. Currently‚ it runs 10Base-T Ethernet and relies on 35 hubs to connect every user workstation to the network. Most of these workstations were purchased within the past two years‚ when the firm experienced a growth

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

410 August 8‚ 2006 Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level‚ the topology of a network refers to the way in which all its pieces have been connected. That is‚ it refers to the layout of the computers‚ printers‚ and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network‚ network ’s topology is also a function of the way in which the cabling is

Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single backbone segment (length of cable) that

common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices." In a logical network layout‚ IP addresses are

designer. The physical design of this application is the material layout of the logical plan. The physical design or topology of a network refers to the configuration of cables‚ computers‚ and other peripherals. The logical topology is the method used to pass information between workstations. A logical topology describes how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables. Logical versus physical can also be described as high-level

A network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks. There are four type of network. First‚ star topology. It interconnects many nodes through a central computer system‚ say a server. When sending a message

Homework 2 Network Topologies PRACTICE Activity 2: Network Topology Paper A hierarchical network resembles a star network in that several computers are connected to a central host computer. However‚ these "client" computers also serve as host computers to next level units. Thus‚ the hierarchical network can theoretically be compared to a standard organizational chart or a large corporation. Typically‚ the host computer at the top of the hierarchy is a mainframe computer. Lower levels in
