Data Communications Networking

The term data communications networking can seem daunting. Experts define data communications as the means and equipment “designed to provide or gather information needs to communicate beyond itself to similar equipment or to a dissimilar system.” Whew! That definition may not help to clarify any confusion. So what exactly is data communications networking?
To start, a more straightforward explanation of data communications is simply the way information is transmitted and communicated from point A to point B. The technology involved in data communications allows two computers to be able to share information, regardless of the distance between them. We often take such technology for granted. For example, when we buy something online, we are putting data communications to use.
When used in the business world, data communications networking serves a crucial role; contract negotiations and client information are each communicated from one point to another through this technology.
Many options exist when establishing a data communications network. The first is a local area network, or LAN. Computers linked using this setup typically are within close proximity to one another. Office buildings and schools use this type of network. In most cases, an organization privately owns the network.
In contrast, Wide Area Networks, or WANs, are public systems. This data communications network links computers over long distances using a variety of cable, satellite and microwave technologies.
Metropolitan Area Networks, or MANs, lay in the middle ground between LAN and WAN networks. They typically suit areas falling in-between LAN and WAN classifications in terms of size. A MAN uses 100 or more miles of cabling, and can thus serve the major portion of many cities using baseband technologies. Many of us have heard the term Ethernet before, but few know what it actually signifies. An Ethernet network is a type of baseband technology.
Broadband networks use radio frequency signals. LANs tend to utilize this technology, which uses coaxial/fiber-optic cables to send information signals. The advantage of this type of network lies in its versatility; broadband technology can simultaneously accommodate television, voice, data and many other services over multiple transmission signals.
Though many people know little about the technical mechanics of the vast web of connections through which we communicate when we send e-mail or surf the Net, without this technology, the world would not be able to function as it currently does. If not for the LANs, WANs and MANs, data communications networking would not be possible on today's scale.
