The Data Network

The Data Network

Before proceeding to determine the meaning of the term that now occupies us, it is important to make clear its etymological origin. In particular, we can establish the following information in this regard: 

• Network, comes from Latin. More exactly 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 network is a structure that has a characteristic pattern . You can refer to the interconnection of computers and other devices that share resources.

Data is a term that indicates an information , adocument or a testimony that allows to reach a knowledge or to deduce the legitimate 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 their objectives, with a specific architecture to facilitate the exchange of content.

However, we can not 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, 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 speak of 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: 

• Servants, who come to be like the administrators of the information and the whole 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. 

Cables known as Pach Cord or 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 , sizeand 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 ), 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 , on the other hand, provides coverage in an extensive geographical area and the WAN network , in a wider geographic area. This means that a WAN data network will allow sharing data over a large area.
