Shutter speed is the time of length in which a camera shutter is open to expose the light into the camera sensor. Different shutter speeds affect whether the image is motion blurred or whats happen in the picture is captured as a freeze frame.
This has uses in advertising most commonly, advertisements of cars and other vehicles often use a slow shutter speed to give the effect of motion in the cars or motorbikes tires/wheels. This captures the effect of motion perfectly in what would look like an ordinary still image if done otherwise.
Despite slow shutter speeds being most commonly used in advertising, photographers also use it in landscape photographs, the slow shutter speed creates a sense of motion in places like waterfalls or rivers but also keeps everything else in focus.
How shutter speed is measured -
Shutter speeds have two different types of measurement, the first one is in fractions of seconds. This is only used when the time it takes to capture the image is less than a second. A common shutter speed in this category would be 1/250, this means that the image was taken in one two-hundred-and-fiftieth of a second or four milliseconds for a much simpler way of thinking about it.
DSLRs these days can handle shutter speeds of up to 1/4000th of a second and some even 1/8000th of a second and faster. The same camera's are also capable of shutter speeds of 30 seconds without external help.
This diagram shows how that shutter speed increases, what you'll see and get as a result will change. A cool thing you can do with a low shutter speed is create light paintings. To create such things like light painting a tripod is needed to hold the camera still where lasers or light sources are used to create illustrations in the foreground.
Here are a few examples of light painting:
