Networking Hardware: The Works of a Router

Perhaps you’ve heard about wireless networking and how it makes life so much simpler and easier by not giving its users any hassle in dealing with all those wires and cables. You may also have known about the term “router.” But do you know that it plays an important role in wireless connectivity?

By definition, a router is a networking hardware that identifies the right path that data must travel with regards to various networks. This may mean a connection for your local area network to a wireless area network so users among these interconnected PCs will have the ability to access the Internet.

Network routers are complex hardware. Thus it is highly necessary that its work is discussed in simplest form as possible. So let’s simply assume that you’re going to send an electronic mail to someone who may be residing in another place, perhaps a country. Have you ever wondered how he or she can get your message when, in fact, there are millions of PCs connected to the Internet? This is where routers come in. They help in transmitting messages from one particular computer to another by transferring these messages not within networks but directly to another PC.

Get the picture? Here’s another example. Let’s pretend that there are two departments, which will be labeled as Department A and Department B. They both have 5 employees. There will be a time when Employee 1 of Department A will send an electronic message to Employee 4 who works in Department B. Now every department in this office belongs to its specific computer network. The router will then link these two networks all together so they can have the ability to “communicate” to each other.

This device will oversee these two particular networks. You may ask, however. Why not just set up one entire network for both? Yes, but then, we will have traffic burden. This happens if employees of Department A will send massive information to Department B. This will basically slow down the speed and transmission time.

The configuration table helps the router identify where to practically send the message. It is mainly composed of information in terms of what network is connected to a particular IP address, as well as the different standards being used in handling and transferring of information among networks.

This then limits the router to two basic functions. First, it ensures that information goes directly to a particular PC, avoiding any clogging of too much data in the network. Second, it makes sure that the right information is sent to the appropriate recipient.
