Network Topology

Computer Networks - Types of network Topologies

Why should learn Network Topology?

Network topology definition

Network topology there are 4 most important computer network topologies use in LANs bus, ring, megastar and mesh.  In a bus topology all gadgets are connect to a important cable, name the bus or backbone. This topology is enormously cheaper and smooth to install for small networks.

This topology is rather pricey and hard to install. But it offers excessive bandwidth and can span big distances.

In a celebrity topology all gadgets are connect directly. To a important computer or server.

The mesh topology can be either. A complete mesh or a partial mesh. In the former, every PC is join at once. To every of the others. The latter includes or greater famous. Person networks hook up with a linear bus.

The word topology comes from the Greek phrases “topos” meaning region and logos which means have a look at. It is a description of any locality in terms of its format. Topology is a branch of arithmetic challenge. With homes of geometric figures. Which are distort without tearing or bonding collectively.

What is network topology?

There are two ways of defining community geometry. The bodily topology and the logical (or sign) topology.

Types of Network topologies

In therefore bus community topology. Every node is connect in series along a linear course.  This arrangement is discovered today normally in cable broadband distribution networks.

In the star community topology. A relevant node has a direct connection. To all other nodes.

In the hoop community topology, the nodes are connect in a close loop configuration. Some rings will skip records handiest in a single route, whilst others are capable of transmission in both directions. Metro networks base on Synchronous Optical Network Technology (SONET) are the number one example of ring networks today. Meshing to create a couple of paths increases resiliency under failure, however increases value.The Internet is a mesh network.

Many large Ethernet switch networks along. With information center networks, are configure as timber.

What are the 5 Network topologies?

Therefore are four classes: Star topology, Bus topology, Ring topology and Mesh topology. Hybrid combinations of these topologies also exist. Star topology all computers.However and devices are connect. Therefore to a prime hub or switch. Star topology is the most commonplace form of network. And follows the Ethernet widespread.

BUS Topology

Therefore Bus topology is a community kind. In other hand which every laptop. However and network device is connect to single cable. When it has exactly two endpoints, then it is call Linear Bus topology.

Features of Bus Topology

  1. It transmits information.  Handiest in a single route.
  2. Every tool is hook up. To a unmarried cable

RING Topology

Exactly two neighbors for each device.

Features of Ring Topology

  1. In Dual Ring Topology. Two ring networks are fashion. However and facts waft is in contrary direction in them. Also, if one ring fails. Therefore second ring can act as a backup. To short up maintain the network up.
  2. Data is transfer in a sequential way this is little by little. To clarify  Data transmit, has to pass through every node of the community. Until the destination node.

STAR Topology

In other words  this sort of topology all of the computers are relate. Therefore a unmarried hub via a cable. This hub is the vital node. And all others nodes are link to the vital node.

Features of Star Topology

  1. Every node has its very own devote connection to the hub.
  2. Hub acts as a repeater. For information waft.
  3. Can be use with twist pair. Optical Fiber or coaxial cable.

MESH Topology

Therefore it is a point-to-point connection to other nodes or gadgets. But all the network nodes are connect to each other. Mesh has n (n-1)/2 bodily channels to hyperlink n devices.

There are strategies to transmit statistics. However over the Mesh topology, they’re.

  1. Routing.
  2. Flooding.

MESH Topology: Routing

In other words routing, the nodes have a routing good judgment. However as in keeping with the network necessities. Like routing common sense. Therefore direct the data to attain the destination. Therefore use of the shortest distance. However or, routing good judgment which has data about the damage links. But  it avoids the ones node etc. We can actually have routing good judgment. But re-configure the fail nodes.

MESH Topology: Flooding

In short up flooding, the same statistics is transmit. To all the community nodes. Therefore no routing logic is need. The community is robust. And the it’s impossible to lose the information. But it ends in unwant load over the community.

Types of Mesh Topology

  1. Partial Mesh Topology: In this topology some of the systems are connect inside the equal style as mesh topology. But a few gadgets are handiest hook up with or three devices.
  2. Full Mesh Topology: Each and each nodes or gadgets are connect to each other.

Features of Mesh Topology

  1. Fully join.
  2. Robust.
  3. Not flexible.

TREE Topology

Therefore it has a root node and all different nodes are hook up with it forming a hierarchy. This is also known as hierarchical topology. They must at the least have 3 tiers to the hierarchy.

Features of Tree Topology

  1. Ideal if workstations are locate in agencies.
  2. Used in Wide Area Network.

HYBRID Topology

Therefore it is exceptional kinds of topologies. That is a combination of or extra topologies.

Features of Hybrid Topology

  1. It is a mixture of or topologies
  2. inherits the benefits and downsides of the topologies include.

What is Network Mapping?

Therefore network mapping is a technique use to find out new gadgets. To short up Interfaces and visualize bodily. But and digital community connectivity. So network mapping helps in breaking down the community thereby simplifying community renovation and control. To short up Network scanners come across. Therefore  community with all its components. And grants the list of devices. This can be use to create a community map. However or a community topology. However network mapping gear integrate the system of scanning and mapping and maps a network mechanically. Therefore OpManager, the automate network mapping software program.  In short up lets you configure and generate network maps effortlessly.

Therefore automate network map visualize. And pinpoint network outages. And overall performance degradation with OpManager

Network topology advantage and disadvantage 


  • It is nice-ideal for small networks.
  • There is easy to installation, take care of, and implement.
  • They charges very much less.
  • In this topology, every node has the possibility. To transmit information. Thus, it’s far a very prepare community topology.
  • Therefore adding or disposing of of network nodes is easy. Because the method requires converting best connections.
  • The site visitors is unidirectional and the information transmission is excessive-seep.
  • The records being transmit among two nodes passes via all of the intermediate nodes.
  • A principal server isn’t require for the control of this topology.
  • In short comparison to a bus, a hoop is better at dealing with load.
  • The configuration makes it easy. To short up identify faults in community nodes.
  • It is less high price than a star topology.
  • Point-to-point contact between each pair of nodes. To clarify makes it smooth to perceive faults.
  • As a result the evaluation of visitors is easy. The topology poses lesser protection chance


  • It is not clean to isolate faults. However within the community nodes.
  • It is suitable for networks with low site visitors. However high visitors will increase load at the bus. And the community efficiency drops.
  • Therefore cable length is restrain. This limits the quantity of network nodes that can be link.
  • This network topology can perform well simplest. However  For a confine number of nodes. When the wide variety of devices relate. To sum up  the bus increases, the efficiency decreases.
  • It is heavily depending on the significant bus. However a fault in the bus leads to community failure.
  • In short each device on the community “sees” all the facts being transmit. As a consequence posing a protection danger.
  • Data dispatch from one node to some other has. To clarify skip thru all the intermediate nodes. That is to say makes the transmission slower in evaluation. To that during a celebrity topology. Therefore transmission velocity drops with an boom. Inside the wide variety of nodes.
