Generally, they are used to pull an input to a known state when there is no driving signal.

But they do have other uses.

pull up means resistor from output point to +ve, pulldown means resistor from output point to -ve .The condition when no output is awailable at the output point , your pulledup+ or pulldown - will prevail
