See CSMA/CD.

Devices at each end of a link are designed to detect collisions instantly and attempt to resend. This is the principle on which CSMA/CD is based and the access control method for Ethernet. An alternative is to resend if there is no acknowledgment of receipt from the remote device.

The process of determining if any pixels for two images share the same location on the screen. See also hit detection.
