- 1When converting an analogue sound into digital, the bigger the sample size meansA bigger range of sounds can be used. However this will make the file size larger because more binary will be used per sample.
- 2When converting an analogue sound into digital, what does "sampling rate" mean?How many samples of the sound is taken per second.
- 3Define the term "Resolution"The number of pixels per inch (PPI).
- 4Reducing the amount of colours in the image willReduce the amount of binary needed for each pixel.
- 5How does a computer convert analogue music into a digital file?The analogue sound is inputted and samples of the sound are taken at regular intervals. These samples are stored as binary.
- 6When converting an analogue sound into digital, increasing the sample rate will meanMore samples will be taken, therefore the sound will be closer to the analogue recording. However the file size will be larger.
- 7How could you reduce the file size of an image?Reduce the numbr of colours used per pixel (colour depth)Reduce the dimensions of the image.Compress the file using a lossy compression file type.
- 8Define the term "Colour Depth"The number of bits used per pixel (BPP).
- 9The number of pixels per inch in an image is known as theresolution
- 10How many colours can be used for each pixel if the colour depth is 8 bit?256 colours
