That is one reason why most home cable TV installations require a special technician to set them up, while home networking usually doesn’t.ĭitching coaxial, Ethernet switched over to the use of the twisted pair cables which still drive wired networking today. Coax is heavy, difficult to work with, not very flexible and also expensive. ![]() Coaxial cable is robust and capable of carrying a lot of bandwidth over its thick internal copper wire. The original standard had Ethernet working with coaxial cable, the kind that is used to support cable television. And as such, simplifying the cables the protocol uses also helped to push the standard into widespread adoption. You can’t talk about Ethernet without also talking about cables, since Ethernet is designed for wired networking. However, Ethernet still provides the basis for most internet and digital communications, and also integrates easily with most higher-level protocols, so that is almost never an issue these days.Ĭolorful cables are a key component of Ethernet networks Other than when encountering a collision situation, there is no error correction in Ethernet, so communications need to rely on advanced protocols to ensure that everything is being transmitted perfectly. And because Ethernet now operates using full duplex, the sending and receiving channels are also completely separate, so collisions can’t actually occur over that leg of their journey. Today, that is far less important than it was in the early days of networking because devices generally have their own private connection to a network through a switch or node. Basically, the protocol makes sure that the line is not in use before sending any frames out. Those frames contain standardized information such as the source and destination address that helps the frame route its way through a network.Īnd because computers on a LAN typically shared a single connection, Ethernet was built around the principal of CSMA/CD, or carrier-sense multiple access with collision detection. How does Ethernet work?Įthernet works by breaking up information being sent to or from devices, like a personal computer, into short pieces of different sized bits of information called frames. And on the other end, its simplicity also enables it to work with very tiny, relatively unsophisticated devices such as those that make up the Internet of Things (IoT), without any special configuration required. It can even support the most complex forms of networking, like virtual private networks (VPNs) and software-defined networking deployments.Įthernet has no problem handling bandwidth-intensive applications such as video streaming or voice over IP applications. That means that it works well in data centers, in private or internal company networks, for internet applications and almost anything in between. This is especially true because it allows organizations to use the same Ethernet protocol in their local area network (LAN) and their wide-area network (WAN). Its ability to work within almost any environment has led to its universal adoption around the world. Ethernet works seamlessly with wireless protocols, too. And yet, because of the simplicity by which the communications protocol can be deployed and its ability to incorporate modern advancements without losing backwards compatibility, Ethernet continues to reign as the de facto standard for computer networking.Īt its core, Ethernet is a protocol that allows computers (from servers to laptops) to talk to each other over wired networks that use devices like routers, switches and hubs to direct traffic.
