A connection means many things. From being part of something, to having an affective or family bond. For the purposes of this article, we will define connection as an electronic device that connects to another electronic device, sometimes through another electronic device. This is as simple as saying, I have my computer, it connects to my Internet service provider through another device called a router or modem. That two or several elements have a connection means that they are communicating with each other and that they use the same language to speak between them and thus be able to exchange information. The language in the case of networks, is the protocol (actually a word that describes a language or language) called TCP/IP. It consists of a series of routines that the Connection pretty reliable. As we can check when connecting to the Internet.
A connection can be established with braided cable or with coaxial cable. The braid is a cable that has multiple little cables inside that go in the form of a braid. This way prevents the different “currents” (which are nothing more than data) from interfering with each other. The braiding of cables also serves so that they do not act as an antenna. Not being braided would mean that they would absorb electromagnetic radiation from the environment (radio waves, television, etc.) and interference would be produced that would make the connection quite difficult, due to the amount of waves that would travel within the cable. This type of connection is the most used compared to coaxial (television antenna type cable).
He coaxial cable or television antenna is used rather little, due to its lack of flexibility, but above all because the network connection system of most companies is not prepared for this technology. With the advent of fiber optics, the use of this type of cable is spreading more and more. This is especially true in large cities, where it is more profitable to run fiber optic cable underground.
With fiber optics, you can work connected to a server that is 500 kilometers away, as if you were working with a disk that was on your own computer or on a server connected to a local network or in your own home.
There is also the electrical connection that allows the devices to start up.
