Well, this time I will risk me trying to explain to everyone in a way that it can understand and without the use of jargon (or administered avoid using them) as all devices having ability to connect to a computer network can communicate in the world. It is true that there are networks and networks, certainly there are very large and very small networks, the smallest comprises two systems and the largest comprises the rest of the world devices that are connected to each other, an example of a network is the Internet is nothing more than a large network that allows systems around the world to share information because this is the purpose of a network, or well, this was years ago when it was created the first network that would usher in what today is known as the Internet, if you have curious you can read more about this network called ARPANET. Well, it’s pretty easy, or at least logical form in which computer systems interact, if we are logical and are trying to reduce everything to the minimum exponent see very clearly the operation of any network, is more We will better understand the complex functioning of any computer system. To my I always like it when I explain something trying to find a clear and simple example of real life and where anyone can be based, and for this case I will use the telephone, that that network is bassa in posts, in cabins of telephones, switchboards and many other devices, wired and wireless to allow hundreds of millions of terminals establish communications and share information around the world to the just like a computer network and in many cases even operates through the own network telephony (ADSL lines). We start from an infrastructure that envuleve the world as if it were a fishing net through which laying down exchanges of information but for this look at a few points that should be taken into account and I will try to do so through similarities between the telephone network and the computer network.
