It could be described as key locations for an object or objects in an
animation. An object moves from point a to point b to point c which
would be your keyframes while the frames between would be the motion
frames between those points. You can set up any number of keyframes
to decribe motion between any number of locations or actions within
a scene.

Some animation software will allow you to specify keyframe locations
or actions and will interpolate the movement for you. This is a handy
feature especially in a GUI interface. All you have to do is point
and click the locations for each oject you wish to animate then define
movement paramaters such as speed, arcs, rotations, accelerations, etc
between your keyframe points and it will handle all of the tedious
math for you.
