A software developer is using a microphone and a sound editing app to collect and edit sounds for his new game.
When collecting sounds, the software developer can decide on the sampling resolution he wishes to use.
a) i) State what is meant by sampling resolution.
ii) Describe how sampling resolution will affect how accurate the stored digitised sound will be.
b) The software developer will include images in his new game.
i) Explain the term image resolution.
ii) The software developer is using 16-colour bit-map images.
State the number of bits required to encode data for one pixel of his image.
iii) One of the images is 16 384 pixels wide and 512 pixels high. The developer decides to save it as a 256-colour bit-map image.
Calculate the size of the image file in gibibytes.

iv) The bit-map image will contain a header.
State two items you would expect to see in the header.
v) Give three features you would expect to see in the sound editing app.
