What is the smallest representable part of an image?

• Pixel

• Bit depth

• Sample

• Resolution

What are bitmaps made up of?

• Pixels

• Bit depth

• Samples

• Resolution

How is the resolution of an image calculated?

• Width in pixels * height in pixels

• Colour depth * number of pixels

• Number of pixels squared

• Sample rate * sample resolution * length in seconds

How many colours can a bitmap using 2-bit colour depth contain?

• 2

• 4

• 8

• 16

How many colours can a bitmap using 4-bit colour depth contain?

• 2

• 4

• 8

• 16

Colour depth defines...

• How many bits are needed to store each pixel

• How many pixels are in an image

• The file size of a bitmap image

• The sample rate of sound

How is the file size of an image calculated?

• Width in pixels * height in pixels

• Number of pixels in image * colour depth

• Number of pixels squared

• Sample rate * sample resolution * length in seconds

A bitmap image of 10 by 10 pixels using a colour dept of 8 bits would have a file size of around:

• 100 bytes

• 800 bytes

• 400 bytes

• 80 bytes

Sound outside of computers is...

• Analogue

• Digital

In order for sound to be stored in a computer it must be converted to...

• Analogue

• Digital

• Buddhism

• JPEG
