Geometric representation of exactly how the computers are connected to each various other is well-known as topology. There room five varieties of topology – Mesh, Star, Bus, Ring and also Hybrid.

Types of Topology

There space five varieties of topology in computer networks:

*
1. Mesh Topology2. Star Topology3. Bus Topology4. Ring Topology5. Hybrid Topology

Mesh Topology

*
In mesh topology each maker is connected to every other maker on the network through a committed point-to-point link. When we say specialized it means that the connect only tote data because that the two connected devices only. Allows say we have actually n gadgets in the network then each maker must be associated with (n-1) gadgets of the network. Number of links in a mesh topology that n tools would it is in n(n-1)/2.

Advantages that Mesh topology

1. No data traffic problems as there is a devoted link between two devices which method the attach is only easily accessible for those two devices.2. Mesh topology is reliable and robust as failure the one attach doesn’t affect other links and also the communication between other tools on the network.3. Mesh topology is secure due to the fact that there is a point to suggest link therefore unauthorized accessibility is no possible.4. Fault detection is easy.

Disadvantages that Mesh topology

1. Amount of wires compelled to associated each device is tedious and headache.2. Due to the fact that each machine needs to be connected with various other devices, variety of I/O ports compelled must be huge.3. Scalability issues due to the fact that a an equipment cannot be linked with big number of tools with a dedicated point to suggest link.

Star Topology

*
In star topology each device in the network is linked to a main device dubbed hub. Unequal Mesh topology, star topology doesn’t allow direct communication in between devices, a device must have actually to communicate through hub. If one maker wants to send data to other device, it has to first send the data to hub and then the hub transmit that data come the designated device.

Advantages the Star topology

1. Less expensive since each machine only need one I/O port and also needs come be linked with hub v one link.2. Easier to install3. Less amount that cables required due to the fact that each maker needs to be linked with the hub only.4. Robust, if one connect fails, other links will work just fine.5. Easy fault detection because the attach can be easily identified.

Disadvantages the Star topology

1. If hub go down every little thing goes down, nobody of the devices can work without hub.2. Hub requires an ext resources and regular maintenance due to the fact that it is the main system of star topology.

Bus Topology

*
In bus topology over there is a main cable and also all the gadgets are connected to this main cable with drop lines. There is a an equipment called tap that connects the drop heat to the main cable. Because all the data is sent end the main cable, over there is a limit of fall lines and the street a key cable can have.

Advantages the bus topology

1. Simple installation, each cable requirements to be associated with backbone cable.2. Less cables compelled than Mesh and also star topology

Disadvantages of bus topology

1. Difficultly in fault detection.2. No scalable as there is a border of how numerous nodes girlfriend can affix with backbone cable.

Ring Topology

*
In ring topology each machine is associated with the two devices on either next of it. There space two committed point to point links a machine has with the tools on the either side of it. This structure creates a ring thus it is well-known as ring topology. If a machine wants come send data come another an equipment then it sends out the data in one direction, each device in ring topology has actually a repeater, if the got data is intended for other device then repeater forwards this data till the intended maker receives it.

Advantages the Ring Topology

1. Basic to install.2. Managing is much easier as to include or eliminate a maker from the topology only two links are forced to be changed.

Disadvantages of Ring Topology

1. A link failure have the right to fail the entire network as the signal will not travel forward due to failure.2. Data web traffic issues, because all the data is turn around in a ring.

Hybrid topology

*
A combination of two or much more topology is recognized as hybrid topology. For example a combination of star and mesh topology is well-known as hybrid topology.

Advantages of Hybrid topology

1. We can select the topology based on the necessity for example, scalability is our problem then we have the right to use star topology instead of bus technology.2. Scalable together we deserve to further connect other computer networks with the present networks with different topologies.

Disadvantages that Hybrid topology

1. Fault detection is difficult.2. Environment is difficult.3. Design is facility so maintain is high hence expensive.
