Local Area Networks (LANs) were once accustomed to the use of connectors like repeaters and hubs, until Ethernet Switches came to be in the 90’s. Connectors, as their title implies, are those additional pieces that make computers possible to connect with each other. However, Ethernet Switches particularly operate on Layer 2 of OSI Model’s Data Link Layer. Categorized under “network bridges”, these switches are unlike the also known router. Ethernet Switching allows flooding and sharing of all data among all member computers of a network. With routers, on the other hand, relay of data is restricted to a specific device in the network.

In the Ethernet networking technology, the term Bridges could take the place of Switches and the same applies to the other way around. But for one connector to be officially identified as a Switch, it should go through a series of assessments that would have to certify it to abide by the 802.3 Ethernet standard.
Ethernet Switching, although highly similar with the previously mentioned hubs and repeaters, are technically more advanced and efficient. The Switching technology allows device linkages to work in full duplex mode, while the two earlier versions only allow half duplex. Meaning, with switching, receiving and sending out of data transmissions can take place at the same time. Whereas, for the other two, these processes have to be done alternately. With this fact, it is easy to see that switching saves up time by using bandwidth capacities wisely.
Besides such, Ethernet Switching has more features in store which makes it still the front runner the among all connector products. A specific example would be that switches has the skill of interpreting data. When data pass switches, they are inspected for embedded additional information, these information help the switches to find the proper course of signals. Hence, they make transferring easier and the flow of bandwidth traffic lighter. The MAC (Media Access Control) addresses of the hitched computers are also registered to the switches’ memory, making it easy for them to assort directions for the moving data. Hubs and repeaters particularly did not support these features, making them consistent with producing waste of both user time and capacity.
Variants of Ethernet switches vary depending on the performance they were made to cater. With high regard on the type and form of network they are targeted for, these switches also have varying performances. The Unmanaged Switches are the usually smaller types. Their configurations are already fixed and can no longer be adjusted. Because they are designed to be immediately ready for usage, they are preferred by users who are not very feature-demanding such as those from private offices and home. Larger variants are also available under the name of Managed Switches. Unlike the previous, their initial settings could be altered depending on how the user wants. The Virtual LAN. is one of the prided unique skills of this type, because it gives the main computer the power of knowing all sorts of data courses inside the network. They are the choice for wide-scale offices and establishments. Because of their special qualities, they are mostly used by huge companies and wide-networked environments.
For user choice, the switches are also available in both IEEE 802.3 standard and non-standard. As always, Ethernet Switching is just one of the constantly developing technologies for our networking needs. With all the betterment it has caused our generation, it can definitely be ascertained that the coming ages will experience more of this technology.
