What are data networks and why your organization needs one?

1 Sep 2022

Many businesses believe that assigning resources for the creation of a computer network is only applicable to big organizations. The best-case scenario is that they know what a data network is, although they are not aware of the potential for their business model. However, even small companies can take considerable advantages from this infrastructure to simplify processes. In this sense, having a data network will not only allow them to store information in a different device, but also to share software and apps.

At Televes Corporation, we would like to give you some insights about this system and explain why you should consider its implementation at your company.

What are data networks?

Data networks are infrastructures designed to transmit information of any kind from one point to another by means of data exchange. Unlike what one might think, not only are computers involved, but also some elements such as servers and data processing centers (DPCs).

Data networks can also be referred to as computer networks because they require interconnected nodes, be they through cable, fiber optics or wireless. In this sense, many companies often prefer to go wireless, even if cable connection is more reliable, faster and safer.

Types of data networks

There are different types of data networks and it is worth knowing all their features to know which one best suit your business model. Below, you will find the most common types:

Local Area Network (LAN)

This network is intended to connect the company’s computers internally so they can all share data, tools and programs. Because their function is, actually, enhancing interconnection within the organization, it is limited to a small geographical area. To deploy this type of network, coaxial cable and braid cable are normally used.

Metropolitan Area Network (MAN)

This type of network covers larger areas compared to LAN and can connect two or more computers in the same city or nearby. It is designed to bring high-speed connectivity.

Wide Area Network (WAN)

This network is used when computers need to be connected in very large areas, that is, at a regional, national or even international scale.

Elements required to create a data network

To roll out a data network, different elements are needed, among them:

  • A router to allow for data transmission
  • A transmission medium, either through cable or wirelessly
  • A server to provide the company with a series of resources such as an e-mail system, DNS, file storage, among others.
  • A switch to filter and resend frames amongst segments of the LAN or local area.
  • A termination point, such as networked printers or other storage devices.
  • A network interface card (NIC), – usually integrated in computers – responsible for connecting you to the network.

Why is having a data network so important?

One of the key factors when explaining why data networks are necessary is cost savings, as less additional hardware is required. To name one example, several computers from a given area can be connected to the same scanner or printer. Not only will you enhance time savings and productivity compared to the use of specific equipment for these additional devices, but it is also much more convenient for the staff.

The right choice for teamwork

In addition, this kind of networks is more suitable for teamwork because data can be shared much quicker and operations can be performed in a more flexible way. The data used by the organization can be stored in any device connected to the network, so there is no need to keep them in a local server. The company’s communications become, therefore, much more efficient.

Greater safety

When well implemented, this type of network brings a higher degree of safety. Considering the increase in companies getting cyber attacked, this aspect is worth taking a closer look.

In short, companies with a great insight into both data networks and the potential for their business model do not hesitate to implement them, as they bring in money savings and make internal processes much more productive.
