Aperture is a function of a camera that allows the lens to collect light. It is the diameter of the lens that opens and is being controlled by the iris. The larger the diameter, the larger light reaches the film. It is being measured in 'f-stops'.

Shutter speed is when the shutter opens and allows light to fall through the lens, which reaches to the sensor. The longer the shutter speed stays open, the more light will be transmitted through the lens. If it is sunny outside, you would use a much shorter shutter speed. Mostly all cameras can automatically adjust to this speed. Shutter speed is measured in seconds.

My camera can't use the aperture and shutter speed mode.
