DCC stands for "Digital Command Control", a registered trademark of the National Model Railroad Association, which created this Standard for communication with locomotives using digital signals through the rails.
While the DCC receiver could be described as a special-purpose computer, I think it's going too far to call it "computerized operation". It is possible to connect a computer with appropriate software to *some* makes and models of DCC command stations, and use that to issue commands to the locomotives, but it would take an extensive detection system, complex programming, and exceptionally reliable equipment to actually permit a computer to operate a model railroad of any non-trivial size and configuration.
DCC is mostly used to permit multiple (handheld) throttles to control multiple locomotives all running on the same set of rails. In addition to speed and direction, common functions often include lights and sound. Some installations include automatic uncoupling, auxiliary animation, or location feedback. DCC can also be used to operate switches and signals, and to detect train location.
Sorry for the lecture. I was the Research Director for the NMRA when this Standard was being developed.
