1. IGCSE ICT Communicating Ideas 2

2.  identify the advantages and disadvantages of using common applications to communicate ideas:  Multimedia presentations  Printing flyers and posters  Websites  Music production  Cartoon animations

3.  In the same way that it is now very easy to create printed documents using IT, it has also become easier to create and edit music with the help of computers.

4.  To produce a musical score (sheets of written notes), you no longer need to write every note down by hand.  You can use a WYSIWYG editor to write the music on the computer, edit it, print copies, etc.

5.  It is possible to play music into a computer and the notes will be recorded - not as sound, but as digital music data.  Your analogue music is converted into digital data using an analogue-to- digital convertor (ADC).

6.  Once you have music data in a computer you can use the computer to play back the music (converting the digital data back into sound with an ADC).  You can add effects to the music, simulate thousands of different instruments, add new 'tracks' of music over the top, etc.

7.  A computer can be used to control musical instruments (or it can be controlled by instruments) using a system called Musical Instrument Digital Interface (MIDI). Most musical keyboards have MIDI connections, as do many electric guitars.

8.  Original recordings can be modified  Electronic instruments can be played back through special effects generators  Synthesizers can combine simple wave forms to produce complex musical creations

9.  Electronic organs & pianos can mimic any instrument  Music scores can be generated from the music!  Automatic correction of music in a score  No need to understand music notation to write music  Print scores

10.  Animations can be produced using computer hardware and software.  With 3D animation, objects are designed on a computer and a 3D skeleton is produced.

11.  The parts of the skeleton are moved by the animator using key frames, tweening and morphing

12.  Go to bbc.co.uk/bitesize  Make notes on the features of Word Processing and DTP software:  Mail merge  Frames  Formatting  Complete the Activity and the Test  Work through the Word Processing and DTP PowerPoints, taking notes Homework
