Why ethernet

When you push the cable into the Ethernet cable, it should click into place. Sometimes, the port will have an LED light in it so the Ethernet jack will light up when successfully connected.

Ethernet cables can vary in length. Sizes usually start at around 0. It is also possible to cut the cables to your preferred length. They come in a variety of different colours too. There is no difference between the colours of the cables. Many computer network administrators will colour coordinate their cables so they can easily manage and maintain their networks.

Typically, Ethernet cables are used to provide an internet connection, connect devices to a local network. They plug into Ethernet ports on a variety of devices. The most common use for an Ethernet cable is connecting a WiFi router or modem to the internet entry port or telephone line. It can also be used to hardwire devices like TVs, computers and other devices that require the internet or a network to work.

There are several different structures when it comes to ethernet cables. The most common structure is Twisted Pair cable. Two wires inside the cable are twisted together. Twisted Pairs is the industry standard cable. They have the best results in terms of maximum length and speed drops.

They are only beaten in performance by fibre-optic cabling. One of the reasons for their quality is that the two cables carry data in both directions, which balances the electrical fields.

This reduces electrical noise within the wire. These additional signals often interfere with the data being carried through the wires. Electrical noise can come from inside the cable, or from outside sources. Ultimately, the more electrical noise, the lower the quality of the signal.

While unshielded cables are much cheaper, the signal quality decreases through electrical noise. Shielded cables come with braided or foil shielding, which is usually made of copper or another conductive polymer.

Shielding reduces electrical noise and improves connection quality. Straight-through cables, often known as patch cables, are used to connect different types of devices. For example, a computer to a router. Crossover cables are used to connect two devices of the same kind, for example, connecting two computers. Solid cables are generally used for business networks and offer a slightly better service than stranded.

They consist of a single run of wire. They cheaper to produce, and so are often much more affordable than their stranded counterparts. Stranded cables contain a few smaller wires which work together. Most patch cables are stranded cables. Stranded cables are more robust in terms of breakage.

They are better suited for home use. Ethernet cables come in different variations, known as Categories or Cat. Each category refers to a different set of standards. As the standards change over time, new categories are created. Currently, the lowest recommended standard available is Cat5. Anything under that is now obsolete.

An Ethernet network usually is active in a km periphery. This extension to fiber optic cable significantly increases the distance covered by the network. Here are some types of Ethernet networks:. Ethernet may be either a wired or wireless network. In a wired network, various types of cables are used. Here are some widely used Ethernet cables:.

Fast Ethernet : As the term suggests, this is quite a high-speed internet, and can transmit or receive data at about Mbps. This type of network is usually supported by a twisted pair or CAT5 cable. Gigabit Ethernet : This type of network transfers data at an even higher speed of about Mbps or 1Gbps. This recipient consumes the packet. If the is already on the highway, the device that wants to send stays back for some thousands of second to try again until it can send.

Moreover, there are also limitations of Ethernet cables. An Ethernet cable like an electric power cord features a maximum distance capacity, this means that the cable has an upper limit as to how long it runs before signal loss affects the performance. The ends of the cable must be close enough to each other to receive the signals faster but they must also be away from electrical interference in order to avoid interruptions. Through the router, it connects to the modem that carries internal signal, sends and receives data packet request and routing them to other computers on the network.

Even if the network is not used, for most cases the computer will connect to the modem through an Ethernet cable. The idea was documented in a memo that was written by Metcalfe in where he coined it after the luminiferous aether once postulated to exist as an omnipresent, completely-passive medium for the propagation of electromagnetic waves.

Ethernet competed with Token Ring and other proprietary protocols. With this, it was able to adapt to market realities and shift to inexpensive thin coaxial cable and then ubiquitous twisted pair writing. On the year , Ethernet was clearly the dominant network technology.

Since then, this Ethernet technology has evolved to meet new bandwidth and market requirements.
