Networking Basics: Part 2 - Routers

October 7th, 2006 · No Comments


Even if you are new to networking, you have probably heard of routers. Broadband Internet router.jpgconnections, such as those utilizing a cable modem or a DSL modem, almost always require a router. A router’s job isn’t to provide Internet connectivity though. A router’s job is to move packets of data from one network to another. There are actually many different types of routers ranging from simple, inexpensive routers used for home Internet connectivity to the insanely expensive routers used by giant corporations. Regardless of a router’s cost or complexity, routers all work on the same basic principles.

That being the case, I’m going to focus my discussion around simple, low budget routers that are typically used to connect a PC to a broadband Internet connection. My reason for doing so is that this article series is intended for beginners. In my opinion, it will be a lot easier to teach you the basics if I am referencing something that is at least somewhat familiar to most people, and that is not as complicated as many of the routers used within huge corporations. Besides, the routers used in corporations work on the same basic principles as the routers that I will be discussing in this article. If you are wanting a greater level of knowledge though, don’t worry. I will talk about the science of routing in a whole lot more detail later in this article series.

As I explained earlier, a router’s job is to move packets of data from one network to another. This definition might seem strange in the context of a PC that’s connected to a broadband Internet connection. If you stop and think about it, the Internet is a network (actually it’s a collection of networks, but that’s beside the point). Networking Basics: Part 2 - Routers
