DIGITAL MEDIA !!!!! =]

Well, lets start off. Digital media is all around us, yeah. You can have mobile phones, or as old people say "cellphones", cd's, video's, televison, INTERNET, and video games!!! But one of the most "important" forms of digital media are computers! seriously, they like rule the world, or do they? because behind the computer is the Binary Numeral System! YAY, numeral system!!
Did you know, these systems are used to convert real-world information or represent numeric values using the code of 2 numbers '0' and '1'. I dont think you did... Anyways, each of these numbers '1' or '0' are called bits. Plural, bytes! This is used as information storage in computer science. Bytes can usually consist of 8 bits in computers nowadays but can vary according to the different hardware.

Now moving on, sampling rates. To be honest I dont really know, so I'm going to look it up in wikipedia! What would I do if wikipedia didn't exist? I have no idea. So back to sampling rates, a sampling rate is typically expressed in samples per second, or hertz (Hz), the rate at which samples of an analog signal are taken in order to be converted into digital form. If you dont get what I am rambling on about here is a picture to help you understand. And of course the picture isn't showing up, so here is the link. http://en.wikipedia.org/wiki/File:Sampled_signal.png

COLOUR DEPTH !!!
The colour depth does affect the outcome of an image, it's pretty simple, the higher the number of colours then the more realistic the image will appear. wow. Now i will try again to put a beauitful picture comparing colour depth for you. I really hope this will work! And of course it doesnt. And yes I know you have to click the "add image" button, but its not working.

And yes, I still have more to say. So here it is, okay we know that colour depth effects both still and video digital media. yeah, still with me. But we also know that sampling rates only effect video but not still media. And I dont know why, and I bet you dont either, so I find it my duty to tell you. Well im not sure, but I think because colour depth is constantly changing the colours, and i dont actually know what I am talking about. So I will comeback later and answer this question. okay.

Well anyways, I have other work to be doing, so I'm going to do that now. And yes I realised that I that I am just going on and on, so I will stop. Right..............now.
