A data network facilitates the exchange of information.
Before proceeding to determine the meaning of the term data network , it is important to clarify its etymological origin. Specifically, we can establish the following information in this regard:
• Red, comes from Latin. More precisely, 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.”
Data network concept
A network is a structure that has a characteristic pattern . It can refer to the interconnection of computers and other devices that share resources.
Data is a term that indicates information , a document or testimony that allows knowledge to be obtained or the legitimate consequences of a fact to be deduced.
The infrastructure whose design enables the transmission of information through data exchange is known as a data network . Each of these networks has been specifically designed to satisfy its objectives, with a specific architecture to facilitate the exchange of content.
The development of a data network requires a certain physical architecture.
Its usefulness
However, we cannot ignore that a data network is also put into operation with two other primary objectives: sharing both software and hardware and providing 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.
Components that make the development of a data network possible
When we talk about a data network, we must keep in mind that it must have a series of fundamental elements so that it can be understood as such and also for it to perform its functions without problems:
• Servers , which are like the administrators of the information and the entire process itself.
• Pach Panel's , which are the systems that are responsible for 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 what is known as horizontal type cabling are other proposals that also gain prominence in a data network.
Classification according to type
Typically, these networks are based on packet switching . They can be classified in different ways according to physical architecture , size and distance covered .
According to its scope, a data network can be considered a personal area network ( Personal Area Network or PAN ), local area network ( LAN ), metropolitan area network ( MAN ) or a wide area network ( WAN). ), among other types.
A PAN network is a network that interconnects computers located near 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 , for its part, provides coverage over a large geographic area and the WAN network over an even larger geographic area. This means that a WAN data network will allow data to be shared over a large area.
