Online lecture Word-file - Part 1: Digital vs. Analogue (The science bit)

This article/lecture's first main argument seems to function mainly as an introduction to the concept of "new media" and points out that in this unit "new media" basically refers to "digital media".

Digital, as opposed to analogue means that actual "stuff" is being translated to code. DIGITal is called that because it's made out of DIGITS. Whereas analgue data actually gets physically stored, be it by picture (on an old fashioned film roll) or ridges (on a gramaphone record.)

Digital is a much smaller/streamlined/FASTER and much more precise way of saving and sending files and data. The data is translated into a code made out of 1's and 0's and transferred to the other end where it gets translated back into actual stuff. Of course there can be glitches where the code doesn't arrive 100% correctly which can then lead into a file having a little mistake in it which can cause it to not work at all.

Most of all digital enables to send much more data in less space, if that makes sense at all.

For example: Analogue telly where the airwaves send the actual pictures can only broadcast 5 channels (and in some areas only 4) where as the digital freeview terrestial technology enables 30-ish channels to be sent through the airwaves because they are turned into code first. But in order to receive them you need equipment that can translate the code back into the actual channels. In this case the infamous freeview box we all love so much. But because the broadcast has been turned into a code first and the whole code is translated back to visual/sound the data arrives much clearer which is why digital usually has a sharper picture than analogue. However, sometimes some part of the code can't get picked up properly by the aerial which then causes little parts of missing data which results in those little squary bits on the screen we see sometimes or the picture freezing for a moment. Luckily the box arrives data all the time so the error usually doesn't last very long whereas an error in the sending of one particular file could result in the whole thing not working.

Because things like the internet and mobile communications require a lot of data to be sent continuesly, there is no way things like the internet (esp. broadband!) could've worked if it was based on analogue technology. So yeah, it pretty much can be said that we owe a lot to digital technology and that the arrival of digital technology has changed our daily lives a lot, considering how many things we use every day (mobile/tv/internet, or even mobile TV though the internet!!) wouldn't have existed otherwise!

More to come soon! Esp. more things of how it affects us and stuff.
