Bandwidth explained

14 04 2013

I sometimes write for people who may be raw beginners on the internet, and this will be one of those posts.

There’s a word going around at the moment which you may have heard, especially in discussions about the NBN here in Australia.

It’s Bandwidth.

I’m going to explain to you exactly what bandwidth is.

Imagine that data, is water, and your computer is an empty bath.

Now, imagine there are three sets of taps over your bath.

One tap is really small, it’s only about as wide as a drinking straw.

The second tap is the normal sort of tap that anyone would have over their bath.

The third is huge, it looks more like a fire hydrant than a tap.

Now out of those three, which do you suppose would fill your bath the fastest?

The big tap!

And yes, there would probably be some splashing involved if it was turned on full.

Because the big tap is really big, a lot of water can go through it all at once.

That’s really all it is.

The tiny tap represents Dial up internet, Very slow, It will take hours to fill your bath.

The normal sized tap represents Broadband over copper wires, Fast-ish, but nothing amazing.

While The Big Tap represents Broadband over optical fiber, BIG SPASH, All Done!

Easy?

Wow, Yes, that is a really good way of explaining it to a 57 year old twat.

Now that wasn’t very nice, I know people in their 70s who do very well online.

By the way, I’m 47.
