Network Topology refers to layout of a network: how different nodes in a network are connected to each other and how they communicate. The arrangement of a network which comprises of nodes and connecting lines via sender and receiver is referred as network topology. The various network. Network topology refers to the physical or logical layout of a network. There are two types of network topologies: physical and logical. Physical topology emphasizes the physical layout of the connected devices and nodes, while the logical topology focuses on the pattern of data transfer between network nodes.

Chapter 5: Topology

Every workstation is indirectly connected to every other through the central computer. In the ring network topology, the workstations are connected in a closed loop configuration.

Adjacent pairs of workstations topology in networking directly connected. Other pairs of workstations are indirectly connected, the data passing through one or more intermediate nodes. It also requires more cable than bus topology and is, therefore, more expensive.

Ring In ring topology, the computers in the network are connected in a circular fashion, and the topology in networking travels in one direction.

Each computer is directly connected to the next computer, forming a single pathway for signals through the network. This type of network is easy to install and manage.

If there's a problem in the network, it is easy to pinpoint which connection is defective. It is also good for handling high-volume traffic over long distances since every computer can act as a booster of the signal.

On the downside, adding computers to this type of network is more cumbersome, and if one single computer fails, the topology in networking network goes down. All the nodes topology in networking the network are connected to a central device like a hub or switch via cables.

Failure of individual nodes or cables does not necessarily create downtime in the network but the failure of a central device can. This topology is the most preferred and popular model. In Figure 4, topology in networking rule is adhered to. This rule does not apply to other network protocols or Ethernet networks where all fiber optic cabling or a combination of a fiber backbone with UTP cabling is used.

If there is a combination of fiber optic backbone and UTP cabling, the rule would translate to a rule. The speed of networking switches is vastly improved over older technologies, and while every effort should be made to limit network segment traversal, efficient switching can allow much larger numbers of segments to be traversed with little or no impact to the network.


A linear bus network may be the least expensive way to install a network; you do not have to purchase concentrators. Length topology in networking cable needed. The linear bus network uses shorter lengths of cable.

For example, the NIC may have a connector for accepting a cable, or an aerial for wireless transmission and reception, and the associated circuitry.


In Ethernet networks, each network interface controller has a unique Media Access Control MAC address—usually stored in the controller's permanent memory. The size of an Ethernet MAC address is six octets.

topology in networking The three most significant octets are reserved to identify NIC manufacturers. These manufacturers, using only their assigned prefixes, uniquely assign the three least-significant octets of every Ethernet interface they produce.

Repeaters and hubs[ edit ] A repeater is an electronic device that receives a network signalcleans it of topology in networking noise and regenerates it.

The signal may be reformed or retransmitted at a higher power level, to the other side of an obstruction possibly using a different transmission medium, so that the signal can cover longer distances without degradation.

Commercial repeaters have extended RS segments from 15 meters to over a kilometer [13].
