What is the Relation With Data Communications and Networks? By Derek Rogers At Isnare.com Ezine Articles

Data communications and networks make use of an approach that is totally focused on the Internet and was designed to tackle the issues of communicating system design. In order to get to the data communications and networks, a certain integrated approach is taken. The way that this is done is by an emphasis that will begin right at the top level of the obligations and will work downwards from there; while explaining just how the requirements are completed by the lower layers of the broadcasting chain. Data communications and networks are very important when it comes to services like VoIP, as they make up some of the service.

When one talks about data communications they are referring to equipment that was specially designed to give and gather information that is capable of communicating with other similar equipment and systems. Data communications are the tools that are used to make certain adjustments within the network. A simple example of data communications would be connecting two computers together when they are 100 feet away from one another. A cable can be used to plug into each computer and they will then be connected, creating data communications. There are different factors that have to be taken into consideration when trying to determine how data communication will work. For example, some factors in this case might include security, distance, signaling, topology and protocol.

In another equally simple case, a data communication could be the connection of your computer to the internet through a modem. If you have done this, you have established a steady connection between your computer and the World Wide Web. Every time you click on a link from a website you are requesting certain information from that website and it is given to you in the form of data, whether it is in color, letters or graphics. Data communications and networks are needed in an Internet connection. It makes the connection, and therefore it has to be present at all times.

A network is made up of two or more computers that are joined in order for them to share certain resources such as CD-ROM’s, printers or fax machines. They can allow the exchange of files and they may also allow different forms of electronic communications. These computers can be joined by infrared light beams, cables, satellites, telephone lines or radio waves. There are two major types of networks; these are Local Area network (LAN) and Wide Area Network (WAN). Networks are important when it comes to computers and the communications with other computer networks. You need to know and understand networks in order to be able to use them to their optimum capability.

The Internet is the main example that can be used when one talks about data communications and networks. There are numerous modern connection options and services that can be used and these include ADSL, Voice over Internet Protocol and mobile radio. When it comes to current systems and the importance of them, the aspects that are more traditional such as circuit switching still exist and are available.
