Before proceeding to determine the meaning of the term at hand, it is important to clarify its etymological origin. Specifically, we can establish the following information in this regard:
• Red, comes from Latin. More exactly, it emanates from the word “rete”, which is synonymous with mesh.
• Data. This word is the result of the evolution of the Latin word “datum”, which can be translated as “given”.
A net is a structure that has a characteristic pattern. You can refer to the interconnection of computers and other devices that share resources.
Fact is a term that indicates a information, a document or a testimony that allows to reach a knowledge or deduce the legitimate consequences of a fact.
It is known as data network to the infrastructure whose design enables the transmission of information through data exchange. Each of these networks has been specifically designed to meet its objectives, with a specific architecture to facilitate the exchange of content.
However, we cannot ignore either that a data network is also put into operation with two other primary objectives: to share both software and hardware and to provide support and centralization to the relevant administration.
In the same way, when it is carried out, it is possible to significantly improve the speed and reliability of the exchange of information and reduce costs in the company or entity that decides to create it.
When we talk about a data network, we must bear in mind that it must have a series of fundamental elements so that it can be understood as such and also so that it can carry out its functions without problems:
• Servers, who come to be like the administrators of the information and of the entire process itself.
• Pach Panel’s, which are the systems in charge of organizing all the necessary wiring.
• Hubs, which proceed to undertake what would be the amplification of the signals that take center stage in this exchange of information.
The cables known as Pach Cord or the one known as horizontal type cabling are other proposals that also take center stage in a data network.
These networks are generally based on the packet switching. They can be classified in different ways according to the physical architecture, the size and the distance covered.
According to its scope, a data network can be considered as a personal area network (Personal Area Network or BREAD), local area network (LAN), metropolitan area network (MAN) or one wide area network (WAN), among other types.
A PAN network is that network that interconnects computers located near a person, while a Red lan It favors the exchange of data in a small area (such as an office or a building).
The MAN network, for its part, provides coverage in a wide geographic area and the WAN network, in an even larger geographic area. This means that a WAN data network it will allow data to be shared over a large area.
