Aperture:
The aperture controls how much light is used, It is measured in f-stops which can be high or low e.g a low f-stop lets in lots of light, however a high f-stop doesn't let in a lot of light. The depth of Field is also set by aperture and it determines the amount that's in focus in any picture, for example you can have a narrow/shallow depth of field or a large/great depth of field.
The lower the f-stop the narrower the depth of field, which can be used to isolate an image.
You would make the f-stop higher in order to make the whole image in focus.
The setting on the camera which changes the f-stop is the Av mode

These photos show a range of aperture from small to large. The photos that let in more light have a smaller f-stop and a narrower depth of field which causes the image to focus on one specific object for example the leaves are in focus and the car in the background is blurred.
The photos with a larger f-stop show less light and has a higher depth of field putting the car and the leaves in front in focus.

Shutter Speed:
Shutter speed is responsible to creating more dramatic effects by either blurring an image if there's a slow shutter speed or freezing an image if there's a high shutter speed. It is the length of time a camera shutter is open to expose light into the cameras sensor. When the shutter speed is slower than 1/125 you must always use a tripod so that the object stays still.
Shutter speeds are measured in fractions of a second for example a fast shutter speed is generally above 1/500 to 1/4000th of a second and a slow shutter speed is typically below 1/125th of a second going down to 30 seconds or B for a manual setting so that you can have the shutter open for as long as you wish.
The setting used to change the shutter speed is Tv.
