Aperture
Aperture is the size of the hole the photographer sets in the to allow light onto the sensor. Aperture is also know as f-stop. A low f-stop means the aperture is wider, allowing more light in. A high aperture means the aperture is smaller and allow less light in. The aperture can be changed to adjust how much of the picture is in focus. The higher the aperture the less of the picture will be in focus.
Depth of field is the distance between the closest and the furthest object that will be in focus. A shallow depth of field will be a result of a high aperture. This is good for portraits where you can make the person stand out more by making the background out of focus. A deep depth of field will be a result of a low aperture. This is good for landscape where you cam make all of the photo in focus.
Examples
Below are some examples of different aperture settings. The show the effect on the depth of field when using high and low apertures.
