Network Topologies Analysis and Comparison

The bus topology connects several computers, or nodes, with a communication channel, often a single cable. Computers on a bus either transmit data to other computers on the network or listen for data from other computers on the network. They are not responsible for moving data from one computer to the next. Consequently, if one computer fails, it does not affect the rest of the network. Because the data, or electronic signal, is sent to the entire network, it travels from one end of the cable to the other. If the signal is allowed to continue uninterrupted, it will keep bouncing back and forth along the cable and prevent other computers from sending signals. Therefore, the signal must be stopped after it has had a chance to reach the proper destination address. To stop the signal from bouncing, a component called a terminator is placed at each end of the cable to absorb free signals. Absorbing the signal clears the cable so that other computers can send data. Both ends of the network must be terminated with a terminator. A barrel connector can be used to extend the cables for better reach. A barrel connector can connect two pieces of cable together to make a longer piece of cable which can be helpful in many office situations. However, connectors weaken the signal and should be used sparingly. One continuous cable is preferable to connecting several smaller ones with connectors. Using too many connectors can prevent the signal from being correctly received. There are ways around that. Another handy piece of equipment is known as a repeater, a repeater can be used to connect two cables together. A repeater actually boosts the signal before it sends the signal on its way. A repeater is...

... central node connected to each of the other nodes, usually a smaller computer or terminals, by a single, point to point link. All communications between network devices must pass through the central node. Thus, the central node intervenes to deliver messages to a specified destination. Some pros and cons to the Star Topography would be:
1. Failure of the central node shuts down the entire network.
2 The star network offers the advantage of centralized resources and management.
3 If one computer or the cable that connects it to the hub fails on a star network, only the failed computer will not be able to send or receive network data, thus not affecting the rest of the network.
4. Each computer is connected to a central point, this topology requires a great deal of cable in a large network installation and could cost a great deal of time and money for installation.

## Topologies Comparison Essay

- Topologies Comparison Topologies are categorized into different virtual shapes or structures with the basic types being Mesh, Bus, Ring, and Star. “More complex networks can be built as hybrids of two or more of the above basic topologies.” (Mitchell, 2008) These basic topologies are structured in to networks as Ethernet, Token Ring, FDDI, and wireless networking. Any business or individual making a decision of which type of topology is best used for a specific environment or network should know and understand the advantages and disadvantages of each type of topology, in addition to the advantages and disadvantages of each network type....   [tags: Network Topology]

## Network Topologies Essay example

- Mesh, Bus, Ring and Star topologies The term Topology refers to the physical or logical shape or layout of a network. Communication between different nodes within a network is determined by its topology. Mesh, Bus, Ring and Star are four of the most common network topologies, each with advantages and disadvantages in relation to each other. Mesh Topology The Mesh topology is true to its name in that there are multiple redundant interconnections between network nodes. A mesh network can employ one of two connection arrangements, full mesh or partial mesh....   [tags: Network Topology]

## Network Analysis : Social Network Essay

- 3.3.2 Network Analysis Social network analysis focuses on ties among, for example, people, groups of people, organisations, and countries. These ties combine to form networks, as social network analysts assume that interpersonal ties matter, as do ties among organisations or countries, because they transmit behaviour, attitudes, information, or goods. Social network analysis offers methodology to analyse social relations, it tells how to conceptualise social networks and how to analyse the, where the main gaol of social network analysis is detecting and interpreting patterns of social ties among actors (Nooy et al., 2005)....   [tags: Sociology, Social network, Mathematical sociology]

## Essay about Networking Topologies and TCP/IP Protocol

- Networking Topologies and TCP/IP Protocol Bus Topology It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions from being mistaken as network traffic....   [tags: Network Technology]

## LAN, MAN and WAN Network Topologies Essay

- LAN, MAN and WAN Network Topologies There are many different types of network topologies, but the three most common types are LANs, MANs, and WANs. The LAN topology is probably the most common of the three. The MAN and WAN topologies are used but not nearly as much as the LAN topology is, although the WAN is starting to be used more and more because of the growing population of networks. The LAN (Local Area Network) is used so much because it is used in small areas. Small businesses use LANs a great deal because they are small and they wouldnt need a WAN or a MAN because there business is usually ran out of one or maybe two buildings....   [tags: Papers]

## Network Topolgies Essay example

- What is Topology. In the world of computer technology, the term that refers to the diagramming of connected devices within a network is called “topology”. To phrase it up, “topology” is the structure, layout or shape of the various devices contained in a network. There are various kinds of topologies but the three most common topologies are the bus, the ring, and the star. The bus topology is often mistaken as something else. Bus networks are often confused with the “system bus” that is contained within the computer....   [tags: Networks Telecommunications]

## Essay about Network Networks And The Network

- Networks communicate using the TCP/IP which allows for them to transmit and receive data from another computer on the same TCP/IP Network types Network types consist of LAN and WAN network types which are determined what they are based on the size of the area they are traveling in. LAN is what connects computers in a small local area. This will need to be used in college so that the computers in the college are able to communicate with the other computers in the local area. This will also allow the computers in the local area to connect to the printers which are on the network....   [tags: Internet, Computer network, Mobile phone]
