Questions tagged [collision]

The intersection of one or more objects or concepts, such as communications packets or function names. For questions about collision detection (in computer graphics) use the [collision-detection] tag instead.

May be used to describe graphical elements (as in a game setting), networking (when multiple packets arrive at the same location simultaneously), RF communication when transmissions overlap and interrupt one another or in programming when disparate functions have similar naming conventions (see also namespace).
