Data is a term that indicates information, a document or testimony that allows to reach a knowledge or to deduce the legal consequences of a fact.
The infrastructure is known as a data network whose design enables the transmission of information through the exchange of data. Each of these networks has been specifically designed to meet its objectives, with a specific architecture to facilitate the transfer of content.
However, we cannot ignore either that a data network is also put into operation with two other primary objectives: to share both the software and the hardware and to provide support and centralization to the relevant administration.
In the same way, by carrying it 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 to exercise its functions without problems:
The cables known as Pach Cord or the known as horizontal type cabling are other proposals that also take center stage in a data network.
In general, these networks are based on packet switching. They can be classified in different ways according to the physical architecture, size and distance covered.
According to its scope, a data network can be considered as a personal area network (Personal Area Network or PAN), local area network (LAN), and metropolitan area network (MAN) or a wide area network (WAN), among other types.
A PAN network is a network that interconnects computers located close to a person, while a LAN network favors the exchange of data in a small area (such as an office or a building).
The MAN network, on the other hand, provides coverage in an extensive geographical area and the WAN network, in a wider geographic area. It means that a WAN data network will allow data sharing over a large area.
