As a network of data it works
The machines have changed the completely form to perceive the things.
The form like the information is transmitted it is one from the topics to try inside the functionality of a network of data. The internet is considered since as the network of networks in the world for this it is that all theinformation travels from any place. He sent of files; as documents, images and video has allowed to enlarge the form in that we communicate. The development of the telecommunications in the area of the telematic one has given place to new communication forms.
To generalize the concept we should begin analyzing one of the fundamental parts of a network. It is denominated network of data to thoseinfrastructures or communication networks that it has been designed specifically to the transmission of information by means of the exchange of data.
The networks of data are designed and they build in architectures that pretend to serve to their use objectives. The networks of data, generally, they are based on the commutation of packages and they are classified according to their size, thedistance that covers and their physical architecture.
The necessary elements understand to have access to the network of communications, the transport of the information and the means and procedures (commutation, signaling, and protocols to put in contact to the ends (subscribers, users, terminals, etc) that want to exchange information. Also, numerous times the users are in ends belonging todifferent types of networks of communications, or in networks of communications that being same is still of different property. In these cases, it is necessary to have an interconnection procedure.
Let us begin analyzing how the communication is determined points between two in any part of the world. First we will say that we need from two connected teams to this network of data. These teams havehardware and necessary software for the communication.
When we are set down in ours PC and we want to communicate with another team we give click to a link and there the communication begins. The team A prepares to receive all the necessary information for the sent of data through the network. These data pass to their local characteristic of personal messaging where the protocol ofcommunications IP packs it the it labels and it puts it in road, the messaging local is who he decides like it divides the information and as it packs it. The data in a net based on IP are correspondents in well-known blocks as packages or datagram’s (in the protocol IP these terms are usually used indistinctly). In particular, in IP any configuration is not needed before a team tries to send packages toanother with the one that had not communicated before. IP provides a service of non reliable datagram’s (also call of the best effort, will make it the best thing possible but guaranteeing little).
Two protocols that establish the communication which are exist: UDP is not a protocol guided to connection. That is to say when one schemes A sends packages to one B, the flow it schemes it isunidirectional. The transfer of data is carried out without having carried out a connection previously with the destination machine (B schemes), and the addressee will receive the data without sending a confirmation to the originator (it schemes it TO). This is because the encapsulation of data sent by the protocol UDP doesn't allow transmitting the information related to the originator. For it theaddressee won't know to the originator of the data except his IP. The protocol TCP or Transport Control Protocol provides a reliable transport of bits flow among applications. It is used to send in way reliable big quantities of information, liberating the programmer of applications of having to negotiate the reliability of the connection (retransfers, losses of packages, order in that the packages...
