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.
MESH
MESH topology routes data sent through any of several possible avenues to the receiving node. MESH arrives at its name due to the amount of cabling and connections used to establish this type of topology. MESH topology is expensive to establish as it connects every node to all nodes on the network, however, MESH is considered the most reliable as it has the most redundancy. If one node fails the network can re-route traffic to another node. A MESH topology network can be straightforward to trouble shoot when a problem arises. “Full mesh is usually reserved for backbone networks.” (NetworkDictionary.com, 2008) This type of topology can be found in connection to a WAN or Wide Area Network and is frequently found in conjunction with other topologies to create a hybrid topology.

BUS
BUS topology uses a single cable, or common backbone to connect the nodes on the network. BUS arrives at its name as all nodes are linked by one linear bus or cable; all data sent onto the network transmits the length of the BUS. The node sending communication to the network broadcasts the data onto t...

Essay about Network Topologies Analysis and Comparison - 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....   [tags: Network Topology] 1022 words

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] 1371 words

Different Types of Topologies Essay - A Mesh topology is a style of connecting computers in a network in a fashion where every link has a redundant path. A mesh topology is also known as a self healing network in that if a segment of the network fails for what ever reason then the data can still be transmitted across another linked path. This would include possibly hoping across a few extra network segments to reach the destination but it would be able to do it. This redundancy of course comes with a price for the extra pathing that would be incurred to ensure that every node will be able to see every other node....   [tags: Computer Data Technology] 1109 words

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] 1391 words

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] 379 words

Comaparison of The Crucible and Sommersby Essay - Sometimes two things may seem like they have nothing in common but when analyzed more critically one may find many similarities. A good example of this would be between The Crucible and Sommersby. These two stories may seem like they have nothing in common; one, The Crucible, is about the Salem witch trials, the other, Sommersby, is about a POW returning home after six years. These two stories may appear to be totally different but they do in fact share many similarities. Three of the characters in The Crucible are very similar to three characters in Sommersby....   [tags: comparison compare contrast essays] 796 words

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] 901 words
