Ethernet can best be described as a standard communications protocol which is typically embedded into software and hardware devices. They are mainly intended for building a local area network (LAN). Ethernet was originally designed by Bob Metcalfe in 1973. He designed Ethernet through the combined efforts of Digital, Intel and Xerox and DIX Ethernet became the worldwide standard model for LANs. A basic hardwired LAN will consist of certain components which include two or more computers that need to be linked or networked together, a network interface card (NIC) which can be found in each computer, an Ethernet cable which can be connected to each computer, certain networking software and the use of a networking switch which is able to direct network traffic.
A network interface card will typically be installed on each computer and then assigned with a specific address. The Ethernet cable will then run directly from each NIC to a central switch. This will literally act as a relay and will receive packets of data and then direct them across the LAN. This, in turn, will allow Ethernet networking to create a communication system within which certain data resources can be shared. This may well include printers, scanners and fax machines. You will also find that certain Ethernet networks are wireless. Therefore, rather than using a specific Ethernet cable, wireless NICs are able to use a system of two-way communication to connect the computers. Wireless networks are known to be far more flexible, although they will require a lot more work initially to correctly configure the security settings.
We are now aware that Ethernet cables are typically used to connect electronic devices to the Internet, or to connect devices to each other. However, a common problem is that one cord, or cable, is often not long enough to reach the specific electronic device that you wish to connect to. This is where you can use an Ethernet coupler to actually connect the two Ethernet cords together. An Ethernet coupler is definitely the cheapest and simplest way to connect to separate Ethernet cables. You will find that the majority of electronic stores will stock Ethernet couplers and these can usually be purchased for under five dollars.
You will initially need to plug your first cord directly into the coupler once you have extended it as far as it will reach. A second cord should then be plugged into the other end of the coupler and you will usually hear a small click when either cord has gone all the way in. In order to remove an Ethernet cable from the coupler you simply need to press down on the tiny piece of plastic that holds the cable in place. You then merely need to pull the cable out. This will allow you to plug the other end of your second cable directly into your electronic device’s Ethernet port. It is advisable that you wrap up the extra cord and tie them in place with a piece of tape over both ends. This will not only make everything look neat, but is a vital safety precaution.
It is also extremely important that your Ethernet cords run through an area that will not have many people walking through. If your Ethernet cords are placed in a high traffic area of a room, people are likely to trip over it. Not only is this extremely dangerous for the person who trips, you are likely to yank an Ethernet cord that is connected to an extremely expensive electronic device. This may even cause your device to fall down onto the ground and break. It is, therefore, suggested that Ethernet cables should be run along the bottom of a wall until it is able to safely reach your specific electronic device.
The use of Ethernet is extremely important in the modern age as it allows networking from one computer to another. We are typically unaware of the number of times that we actually access information from computer networks. However, you should consider that the Internet is a prime example of computer networking. The Internet is able to link millions upon millions of computers around the world, although it is important to realize that far smaller networks play a vital role in accessing information on a day-to-day basis. An example of this will be public libraries who have now replaced card catalogues with computer terminals. This will allow patrons of the library to search for a specific book very easily and, of course, quickly. You will also find that the majority of retail stores now have specialized computers that are able to handle point-of-sale transactions. This will allow a shared repository of data to be accessed from numerous devices that are typically found in multiple locations. As computer networking has evolved to encompass new technologies, the standard of Ethernet connections has grown considerably.
