What is aperture?

Aperture is an adjustable opening in the camera lens that limits the amount of light that comes through the lens and hits the camera sensor.
When the aperture is wide open more light is allowed to pass through, this blurs the background and the foreground of the image. The only thing that is in focus is the thing you are focusing on. Wide aperture is good for taking pictures in low lit places because the most possible light gets in also if you're taking a portrait picture because it blurs everything but your subject, creating a shallow depth of filed and making your subject stand out.
When the aperture is at its smallest the least amount of light possible passes through. You use a small aperture when there is a lot of lighting in the background. Using a low aperture allows you to have a slower shutter speed which is good for taking pictures of moving things. For example; taking a picture of a running dog whilst using a low aperture creates a motion effect which brings your image to life.
Aperture is measured in F-Stops. The lower the F-Stop (e.g. f/2.8) the wider the opening of the aperture and the higher the aperture (e.g. f/22) the smaller the opening of the aperture.
Here are some examples of pictures with low and high aperture:
