These two pictures are good examples of a maximum depth of field. They are both landscapes with everything in focus. Notice how the rocks in the second picture are not focused on, and you can still clearly see the mountains in the background.
The photographers of these pictures used a small aperture in order to get a maximum depth of field in the picture. The smaller the aperture, the more clear the picture is.

These two pictures are good examples of a very shallow depth of field. The first picture is of a young girl giving the camera the thumbs up. Notice how her hand is in focus while her face is blurry and unfocused. The second picture is of a purple flower. Notice how the flower in the front is in focus, while the stem and the flower in the background is blurry and unfocused.
The photographers of these two photos used a large aperture in order to get a very shallow depth of field. The larger the aperture, the more selective the focus is.
