Question

• When it comes to networking, there are many different topologies. List at least 4 different topologies and give a brief description of each one. Please kindly give apa citing source.

Answer 1

BUS TOPOLOGY:

Bus topology makes use of a single cable that connects all of the included nodes. The principal cable acts as a backbone for the entire community. One of the computers inside the network acts because of the laptop server. When it has two endpoints, it's far known as a linear bus topology.

Pros:

• The cost of the cable could be very much less as compared to different topology, so it's far broadly used to build small networks.
• Famous for LAN network because they're less expensive and clean to install.
• It is widely used when a community set up is small, simple, or temporary.
• It is one of the passive topologies. So computers on the bus handiest pay attention to statistics being sent, that are not chargeable for moving the information from one pc to another.

Cons:

• Cables are always of a limited length.
• It is slower than the ring topology.
• It has a limited length

Ring Topology:

In a hoop community, every tool has precisely two neighboring devices for verbal exchange cause. It is called a ring topology as its formation is like a hoop. In this topology, each laptop is attached to any other computer. Here, the ultimate node is combined with a primary one.

This topology uses a token to skip the facts from one laptop to another. In this topology, all the messages tour via a hoop inside the equal course.

Pros:

• Easy to put in and reconfigure.
• Adding or deleting a tool in-ring topology wishes you to move the simplest two connections.
• The troubleshooting manner is difficult in a ring topology.
• Failure of one computer can disturb the complete network.
• Offers same get entry to to all the computer systems of the networks
• Faster error checking and acknowledgment.

Cons:

• Troubleshooting is hard in ring topology.
• Adding or deleting the computers disturbs the community interest.
• Failure of 1 pc disturbs the complete community

Star Topology:

In the star topology, all of the computers hook up with the assist of a hub. This cable is known as a primary node, and all different nodes are related using this imperative node. It is maximum popular on LAN networks as they're less expensive and easy to install.

Pros:

• Easy to troubleshoot, install, and adjust.
• Only those nodes are affected, that has failed. Other nodes still paintings.
• Fast overall performance with few nodes and really low community traffic.
• In Star topology, addition, deletion, and shifting of the gadgets are easy.

Cons:

• The cost of set up is excessive.
• Expensive to apply.
• If the hub fails then the whole network is stopped due to the fact all the nodes rely on the hub.
• Performance is based totally at the hub this is it relies upon on its ability.

Tree Topology:

Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also referred to as a hierarchical topology. This topology integrates numerous superstar topologies together on a single bus, so it's far known as a Star Bus topology. Tree topology is a very not unusual community which is just like a bus and big-name topology.

​​​​​​​

Pros:

• Failure of 1 node in no way impacts the relaxation of the network.
• Node expansion is fast and smooth.
• Detection of mistakes is a smooth system
• It is easy to manipulate and hold

Cons:

• Heavily cabled.
• Costly.
• If greater nodes are introduced upkeep is tough.
• Central hub fails, network fails.
