VoIP Explained

Unless you are in the communications industry there is no reason to know how VoIP works. All you really need to know is that it can save you a small fortune and improve your productivity!

But for the curious, here we go.

Normal phone calls use copper wires that are rolled out in the ground. The internet also uses wires but as with wireless broadband cards etc it can also travel through the air like mobile phone calls.

When data travels across the internet it does so by breaking a message up into bits, or packets. Unlike a normal voice call that travels in a sequence, think of it like all your words are traveling in a semi trailor convoy. They're all heading in the same direction in the right order and arrive at the correct time one after the other.

The data equivalent is that information, or packets, travels at different speeds and can arrive at different times. What goes out first is not guaranteed to arrive first. It is more like a jigsaw puzzle. When these data packets arrive at the correct location your computer reassembles them into the correct order. This way what you read on your computer screen makes complete sense.

VoIP is the technology that allows you to speak on a phone, send it over the internet as data packets, and have it all reassembled in a split second so that it sounds completely normal to the person on the other end of the line.

It's really not that difficult is it!
