9. Graphical Design Vector: Vector: Each individual object contained in a vector image is defined by a mathematical equation. This means that vector images are not resolution dependent. Thus, each vector object is scalable and can generally be resized without any loss of image quality. Bitmap/Raster: Use coloured pixels to crate an image and are mapped according to their placement and colour. When stretched the image becomes blocky as the pixels are expanded.

13. Audio Audio is a form of digital media that is converted from an analogue signal to a digital signal through the process of pulse code modulation. Audio is a form of digital media that is converted from an analogue signal to a digital signal through the process of pulse code modulation. The sound can then be converted to a variety of formats including the most common MP3 or WAV. The sound can then be converted to a variety of formats including the most common MP3 or WAV. Reference: http://www.tech-faq.com/pulse-code-modulation.html

14. Audio Reference: http://www.flickr.com/photos/ethanhein/2378146633/ Pulse code modulation process is the translation of a microphone analogue waveform into a digital waveform. Red line represents the continuous voltage, and the stair stepped black line is the digitization process.

15. Audio E-Music is usually available in the MPEG layer 3 (MP3) audio format, which allows data to be stored with minimal loss of audio quality and with small file sizes. All digital data is stored in bits, where the greater the depth of bits the less of the original analogue signal is lost in the conversion process.

19. Video The process involved in digital video production includes the following: The process involved in digital video production includes the following: Camera and a microphone which capture the picture and sounds of a video session and send analogue signals to a video-capture adapter board. The board only captures half of the number of frames per second that movies use in order to reduce the amount of data to be processed.
