Think of it like DSL versus cable home connection. Cable internet is on a shared loop that runs through your neighborhood. Meaning your bandwidth speeds can go up and down depending on the usage of the loop (i.e. your neighborhood). While DSL is a dedicated line to your house and should remain a constant speed at all times.
