"In geometry, the set of all points (and only those points) that satisfy certain conditions; these points form a curve or figure. For example, the locus of all points in space one foot from a given point is a sphere having a radius of one foot and having its center at the given point. The locus of all points in a plane one foot from a given point is a circle having a radius of one foot and having its center at the given point." (www.answers.com).

Yep, a locus is just a set of points. We usually put constraints on which points to include though.

Another example, the locus of points whose distance from two other fixed points is a line. To see this, put two random points on an xy-plane, the midpoint of the two points is one such point that satisfies the condition.
