# Network topology and wiring

Mesh Topology Hybrid Topology More complex networks can be built as hybrids of two or more of the above basic topologies. Star Topology Many home networks use the star topology. A star network features a central connection point called a "hub" that may be a hub, switch or router. Circuit diagrams[ edit ] The circuit diagrams in this article follow the usual conventions in electronics;  lines represent conductors, filled small circles represent junctions of conductors, open small circles represent terminals for connection to the outside world.

In most cases, impedances are represented by rectangles. A practical circuit diagram would use the specific symbols for resistorsinductorscapacitors etc. The Graph theory section of this article gives an alternative method of representing networks.

Topology names[ edit ] Many topology names relate to their appearance when drawn diagramatically. Most circuits can be drawn in a variety of ways and consequently have a variety of names. For instance, the three circuits shown in figure 1.

T,Y and Star topologies are all identical This example also demonstrates a common convention of naming topologies after a letter of the alphabet to which they have a resemblance.

Series and parallel topologies[ edit ] For a network with two branches, there are only two possible topologies: Series and parallel topologies with two branches Even for these simplest of topologies, there are variations in the way the circuit can be presented.

## BUS Topology

All these topologies are identical. Series topology is a general name. Voltage divider or potential divider is used for circuits of that purpose. L-section is a common name for the topology in filter design.

For a network with three branches there are four possible topologies; Figure 1. Series and parallel topologies with three branches Note that the parallel-series topology is another representation of the Delta topology discussed later.

Series and parallel topologies can continue to be constructed with greater and greater numbers of branches ad infinitum. The number of unique topologies that can be obtained from n branches is 2n The total number of unique topologies that can be obtained with no more than n branches is 2n This transform is important because there are some networks that cannot be analysed in terms of series and parallel combinations.

Say it is desired to calculate the impedance between two nodes of the network. In many networks this can be done by successive applications of the rules for combination of series or parallel impedances. However, star topology may also refer to the more general case of many branches connected to the same node rather than just three.

Common balanced and unbalanced filter topologies The topologies shown in figure 1. The L-section is identical topology to the potential divider topology.

The T-section is identical topology to the Y topology.

## Network topology - Wikipedia

All these topologies can be viewed as a short section of a ladder topology. Longer sections would normally be described as ladder topology.Top 10 Network Diagram, Topology & Mapping Software Reviews Network Diagrams are essential for ensuring your have a complete understanding of how your network topology is interconnected and can give you an overhead view of whats going on in your network.

Network topology is the layout of the connections (links, nodes, etc.) of a computer network. The mapping of the nodes of the network and the physical connections between them – the layout of wiring, cables, the locations of nodes, and the interconnections between the nodes and the cabling or wiring system.

Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network.. Network topology is the topological structure of a network and may be depicted physically or logically.

It is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the . This network topology is used in small networks, and it is simple to understand.

Network topology is the layout of the connections (links, nodes, etc.) of a computer network. The mapping of the nodes of the network and the physical connections between them – the layout of wiring, cables, the locations of nodes, and the interconnections between the nodes and the cabling or wiring system. Many network standards dictate the type of topology which is used, while others are more versatile. Ethernet, for example, is commonly implemented in a “bus” topology but can also be implemented in a “star” or “ring” topology with the . A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator (See fig. 2). Data on a star network passes through the hub, switch, or .

Every computer and network device connects to the same cable, so if the cable fails, the whole network is down, but the cost of setting up the network is reasonable. The network-wiring port interconnections are specified in a special file called pfmlures.com DOT is a plaintext graph description language.

It is a simple way of describing graphs that both humans and computer programs can use. A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator (See fig.

2). Data on a star network passes through the hub, switch, or concentrator before continuing to its destination.
