Perhaps this post required a bit more explanation.   Below is what you lot come up with when given free range on a blog post.   I was showing the wordpress interface in this lesson as it is an excellent real life example of both a WYSIWYG (What you see is what you get) and a text editing web publishing tool.   You can use either (depending on how good your HTML is).

To recap:

• Text editors require lots of skill and knowledge (to write code)
• Making a page in a text editor doesn’t always come out how you thought
• Text editors don’t require fancy (power hungry) software
• WYSIWYG editors are easy to use and don’t need much training
• Scar is bad.

Be prepared.

Our teeth and ambitions are bared.

Boo.

• Data representation
• Computer Structure
• Peripherals
• Computer networks
• Computer Software (we haven’t done this yet)

Have a read through the slide below about peer to peer networks, it is one of the harder parts of the networking topic….

And here is a slamball poster.

So I have missed too many lessons to summarise them in the normal way here, but they are all on Studywiz, click the picture below to get there.

Also, I have been playing with Flowgram and came up with this so far (it is a work in progress) so now you can have me narrate the slides while you revise! I am sure this is what you have all been secretly waiting for…..

Audio data

Today we tried to look at some examples of multimedia appplications created using authoring software.    Unfortunately they seemed to be a bit much for the network connection in school but you could have a look now if you are so inclined.  They were catapults, car maintenance, and furniture assembly.  The point about of all of them was that they are on the whole more complicated pieces of multimedia than you could create using presentation software (like Powerpoint).   

These are the notes from today.

We had a quick look today at the difference between using a WYSIWYG editor and a text editor to make multimedia applications.   The reason the class created blogs was to try and demonstrate that WYSIWYG editors are easy to use and don’t require any prior knowledge of code, unlike typing in HTML into a text editor.  I am hoping the blogs will come in useful elsewhere too though….

Here are the notes the class received today.

Also, I had to clear up the fact that a common design process used for multimedia applications is known as a storyboard (a graphical representation of the layout of a multimedia application showing navigational links), as demonstrated here by this not particularly helpful, yogi bear episode storyboard.

The main idea is that you should have an understanding of how something like the text below, turns into the two shapes below it…..

  <rect x="80" y="60" width="250" height="250" rx="20"
fill="red" stroke="black" stroke-width="2px" />

<rect x="140" y="120" width="250" height="250" rx="40"
fill="blue" fill-opacity="0.7" stroke="black" stroke-width="2px" />


Here are my notes from today:

Sorry there have not been many posts for a while, but then there have not been many Higher Computing lessons for a while. The prelim was yesterday morning and is now in the process of being marked.

If you took advantage of the chat room support the night before you would have realised that calculation questions would be important (along with a lot of other topics!).

If you want extra practice try this question:

A stereo audio file has been recorded at CD quality and is 3 minutes 12 seconds long. It is to be stored on a solid state flash drive. How much space will it take up in an uncompressed format?

Answers as comments please…..

This one (Resource Interchange File Format orRIFF) is a container file i.e. contains more than one type of data.

It is was created by Microsoft and IBM (according to Wikipedia anyway) as a multimedia content file. The header (first section) of the file determines what kind of data is in it. The picture below explains it better than I can.

Here is the slide from todays lesson:
