Which one of the following is false about resolution?
Higher resolution takes up more space.
Resolution refers to the number of pixels per inch.
Resolution is the ratio of width to height of an image.
Lower resolution typically leads to poor image quality.

What are channels in an image?
Channels store an image's colour information.
Channels are used for storing image metadata tags.
Channels represent the number of pixels in the image.
Channels store information about the image's exposure time.
