How many binary values can a nibble store?

• 16
• 8
• 4
• 32

A kilobyte is usually rounded to 1000 bytes. But actually it is _____ bytes:

• 1024
• 512
• 1048
• 9600

The smallest unit of data that use is:

• a bit
• a byte
• a gigabyte
• a megabyte

In computing, a bit is

• 8 bytes
• a single    0 or 1     on or off

A bitmap image is made up of

• Pixels
• Colours
• Sounds
• Samples
• Characters

Increasing the colour depth means…

• A bigger range of colours can be used for each pixel
• More pixels are in the image.
• More colours are in the image.
• Darker colours

How many colours can be used for each pixel if the colour depth is 4 bit?

• 4 colours
• 5 colours
• 15 colours
• 16 colours

How many colours can be used for each pixel if the colour depth is 8 bit?

• 8 colours
• 9 colours
• 255 colours
• 256 colours

Reducing the amount of colours in the image will

• Reduce the quality of the image.
• Reduce the amount of binary needed for each pixel.
• Make the file size larger
• Remove pixels from the image.

Which is NOT an example of metadata for an image file?

• Resolution
• Colour depth
• Camera used
• Sample rate
