Don't forget to read previous article  > Understanding Conputer Network.



Understanding community topology is a approach used to join one pc with different laptop gadgets that are organized into a network, the place the use of a community topology is associated to the pace of get admission to to data, size, fee and stage of connectivity that can have an effect on the effectivity of a network.

Network topology can additionally be interpreted as a laptop community format that is fashioned and explains how computer systems can be interconnected between one gadget and another. There are a number of sorts of laptop community topologies that are frequently used today, such as Bus Topology, Ring Topology, Star Topology, Tree Topology, and Mesh Topology. For greater information, please refer to the dialogue that has been summarized from a range of sources.

And right here are the a range of laptop community topologies that I will give an explanation for in this article, namely:
a. BUS Topology
b. Star Topology
c. Ring Topology
d. Mesh Topology
e. and Tree Topology

1. Topology of Bus



This topology is the first topology used to join computers. in this topology every pc will be linked to a lengthy cable with various terminals, and at the cease of the cable need to be terminated with a terminator. This topology is very hardly ever used in constructing everyday laptop networks due to the fact it has quite a few shortcomings which includes the opportunity of a information go with the flow collision, if one machine breaks or there is injury to one section of the computer, the community will no longer feature without delay earlier than the injury is resolved.

BUS Topology Characteristics:

  • The nodes are linked serially alongside the cable, and at each ends of the cable are closed with terminators.
  • Very easy in installation.
  • Very not pricey in cost.
  • Data packets pass every different on a cable.
  • No hub required, all you want is a Tconnector on every ethernet card.
  • The hassle that frequently takes place is that if one node is damaged, the complete community can be down, so that all nodes can't talk on the network.

Advantages of BUS Topology

  • Does no longer require a lot of cable resources
  • The fee is additionally more cost-effective than different topologies
  • not too tricky if we desire to make bigger community coverageVery simple

Disadvantages of BUS Topology

  • Not suitable for heavy community traffic.
  • Any barrel connector used as a connector weakens the electrical sign being transmitted, and most will forestall the signal from being acquired properly.
  • It is very tough to troubleshoot the bus.
  • Slower than different topologies.

2. Topology of STAR



In this topology, every laptop is linked to every different in such a way that it varieties a star, the place every machine is related to every different round the hub/switch as the concentrator. This topology is the most often used in LAN (local Area Network) networks. This topology is regularly used in homes, offices, schools, laptop labs, and so on. All computer systems linked to the celebrity topology require a hub, switch, or router with the transmission medium being a UTP / STP cable.

Star Topology Characteristics:

  • Each node communicates immediately with the concentrator (HUB).
  • If each and every statistics packet that enters the concentrator (HUB) is then broadcast to all nodes that are related very tons (for instance the usage of a 32 port hub), then community overall performance will decrease.
  • Very effortless to develop.
  • If one ethernet card is damaged, or one of the cables in the terminal is broken, then the whole community can nonetheless talk or there is no downtime on the whole network.
  • The kind of cable used is generally UTP type.

Advantages of Star Topology:

  • It is pretty convenient to exchange and add computer systems to a community that makes use of a famous person topology except interrupting ongoing community activities.
  • If one laptop is broken in the network then that laptop will now not kill the whole community star.
  • We can use a couple of cable sorts inside the equal community with a hub that can accommodate special cable types.

Disadvantages of Star Topology:

  • Has one fault point, lies in the hub. If the central hub fails, then the whole community will fail to operate.
  • Requires extra cables due to the fact all community cables need to be pulled to one central point, so it requires greater cables than different community topologies.
  • The quantity of terminals is limited, relying on the ports on the hub.
  • Heavy facts site visitors can reason the community to work greater slowly.

3. Topology of Ring



This kind of ring topology, all computer systems are linked to structure a closed circle (ring) and are assisted via tokens.sal from the supply pc which will test whether or not the statistics is used through the factor in question, if there is then the token will furnish the information requested by way of the community factor and go to the subsequent point. all computer systems will acquire each facts sign that flows, facts will be obtained if it is in accordance with the meant address, and the statistics sign will be overlooked if it is no longer the tackle itself. In different words, this procedure will proceed till the facts sign is obtained at the destination.

Ring Topology Characteristics:

  • The nodes are linked serially alongside the cable, in a round community shape.
  • It is very easy in format like this kind of bus topology.
  • Data packets can go with the flow in one route (left or right) so that collisions can be avoided.
  • The hassle faced is the equal as the bus topology, namely: if one node is broken then all nodes can't speak in the network.
  • The kind of cable used is generally UTP cable or Patch Cable (IBM kind 6).

Ring Topology Advantages:

  • Data flows in one path so that collisions can be avoided.
  • The information movement flows quicker due to the fact it can serve information from the left or proper of the server.
  • Can serve the go with the flow of heavy facts traffic, due to the fact records can pass left or right.
  • Time to get admission to records is extra optimal.

Disadvantages of Ring Topology:

  • If there is one pc in the ring that fails to function, it will have an effect on the complete network.
  • Adding or casting off computer systems will mess up the network.
  • Difficult to reconfigure.

4. Topologi MESH



In the mesh topology to join computer systems to one another, you can use a single cable, so in the manner of sending statistics from one pc to another, you will be capable to at once attain the vacation spot laptop except passing via any other laptop or thru a change / hub.

Mesh Topology Characteristics:

  • Mesh topology has redundant relationships between present devices.
  • The association is that each gear in the community is related to every other.
  • If the wide variety of related gear is very large, of path this will be very tough to manage in contrast to solely a few linked equipment.

Advantages of Mesh Topology:

  • The principal benefit of the use of a mesh topology is fault tolerance.
  • capacity of the comunication channel is guaranted, due to the fact has greater relation.
  • It is exceptionally simpler to do troubleshoot.

Disadvantages of Mesh Topology:

  • The concern in putting in and reconfiguring when the range of computer systems and linked tools is growing in number.
  • The excessive fee of retaining immoderate relationships.

5. Topologi Tree




The tree topology is a mixture of countless superstar topologies related to the bus topology. So every megastar topology will be linked to different famous person topologies via the use of a bus topology. Usually in this topology there are countless community levels, and the community at a greater stage can manipulate the community at a decrease level.

Advantages of Tree Topology

  • The hierarchical centralized association of data, it makes records administration higher and easier.
  • Easy to enlarge into a wider network.

Disadvantages of Tree Topology

  • If the pc that occupies the easiest degree has problems, then the pc beneath it additionally has problems
  • Network overall performance in this topology is pretty slow.
  • Using more than one cables and the backside cable (backbone) is the core of this technology.
