Uses of Ethernet

The most basic use of ethernet is to connect different devices present in a network, and ethernet is also considered as one of the most popular forms of network connection. Ethernet is generally used for its reliability, speed, and security for local area networks, which any school can use, college, company, offices, and hospitals.

Ethernet came into the picture majorly because of its low pricing compared to its counterparts, including IBM’s Token Ring at the time of its arrival in the industry. Ethernet became popular with time as a result of its ability to deliver and evolve to greater levels of performance, and at the same time, it maintained its compatibility with the earlier versions. At the time of its arrival, ethernet used to give a throughput of 10 megabits per second, and with time it has increased to 100 Megabits per second till the 1990s. The Institute of Electrical and Electronics Engineers Inc. is popularly known as IEEE, is always on its toes to provide the best updates to enhance ethernet’s performance. Nowadays, ethernet can support a throughput of up to 400 gigabits per second.

There are various topologies that ethernet uses. Some of them are explained below:

1. Bus topology

When all of the nodes of a network are connected with a single cable, then it is called a bus topology. The single cable which is used in bus topology is called the backbone. Initially, bus topology was used with 10Base-5 Thick Net and 10Base-2, Thin Net coaxial cable ethernet networks. This topology broadcasts the message sent by one node to all the other nodes connected to the cable. Once the message is sent, then the target node only can process the message. Bus topology is one of the easiest and inexpensive to install topologies.

2. Ring and Double Ring Topology

All of the signals traveling in the network have to travel in a single direction. This is done to avoid data collisions and noise in the network. Sometimes, one of the nodes may be disrupted, and the network fails. So, a double ring topology is used to solve this, which adds another cable to the network to avoid failures.

3. Star and Extended Star topology

For ethernet, star and extended star topology has been the most popular. Star topology and extended star topology is very easy to set up and is also comparatively at a lower side of the price, and have higher redundancy than the other topologies. In star topology, all of the nodes are connected to the central device in the network. The central connection makes sure that the network keeps on working even if any node fails or a cable fails. The only problem with this topology is that what if the central device fails as it will make the network cease to function.

4. Tree/Hierarchical topology 5. Mesh Topology

There are two mesh topology types: one is a partial mesh, and another is a full mesh. In a full mesh topology, each and every node is connected to each other. This makes the network fully redundant and enhances its reliability when compared to other networks. In this topology, even if a link or node disrupts, there are other paths to transfer the data. The major problem with the implementation of this topology is its complexity in configuration, and the topology is on the higher side of the price.

Majorly this topology is used in networks with fewer nodes or a smaller network. Different alternate routes are provided from each node to each other in a partial mesh topology. Some redundancy is provided in this type of topology, and it is majorly used in backbone environments or networks where the services are very important and are also used in wide area networks. Internet is an example of partial mesh topology.

Conclusion

On the basis of the above article, we understood the concept of ethernet and its uses. Various topology in which ethernet is used has been explained in this article in detail to understand how the data is transferred in a network and how it can be transformed for increasing efficiency.
