A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology. Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the. Network topology refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. Alternately, network topology may describe how the data is transferred between these nodes. There are two types of network topologies: physical and logical.

Network topology

Computers in a network are connected in some network topology manner, referred to as network topology or network architecture. Learn about the different types of network architecture. Network Topology Computers in a network have to be connected in some logical manner.

The layout pattern of the interconnections between computers in a network is called network topology.

You can think of topology as the network topology shape or structure of the network. Network topology is also referred to as 'network architecture.

Network topology is illustrated by showing these nodes and their connections using cables. Ring Topology In this network topology the computers are connected together to form a ring shape so that none of the computers is more important than any of the others.

In this diagram the printers is attached to one of the computers in the network. This computer is called the print server and it handles all network topology printing jobs on the network.

The main disadvantage of the ring topology is that the whole network will be affected if there is a break anywhere in the network cabling. Star Topology The star topology has one powerful computer or a special junction box called a hub that controls the network topology network.

If the hub fails then the whole network fails.

Another disadvantage of network topology star topology is that it uses a lot of cable. Commercial repeaters have extended RS segments from 15 meters to over a kilometer [13].

Network Topology

In most twisted pair Ethernet configurations, repeaters are required for cable that runs longer than meters. With fiber optics, repeaters can be tens or even network topology of kilometers apart.

Repeaters work within the physical layer of the OSI model, that is, there is no end-to-end change in the physical protocol across the repeater, or repeater pair, even network topology a different physical layer may be used between the ends of the repeater, or repeater pair.

Repeaters require a small amount of time to regenerate the signal.

This can cause a propagation delay that affects network performance and may affect proper function. As a result, network topology network architectures limit the number of repeaters that can be used in a row, e.

USB networks use hubs to form tiered-star topologies. Ethernet hubs and repeaters in LANs have been mostly obsoleted by modern switches.

Bridges[ edit ] A network bridge connects and filters traffic between two network segments at the data link layer layer 2 of the OSI model to form a single network. This breaks the network's collision domain but maintains a unified broadcast domain.

Network segmentation breaks down a large, congested network into an aggregation of smaller, more efficient networks. Bridges come in three basic types: There are two ways of defining network geometry: The physical topology of a network is the actual geometric network topology of workstations.
