Dynamic Debugging Technique, or DDT, was the name of several debugger programs originally developed for DEC hardware, originally known as DEC Debugging Tape because it was distributed on paper tape. The first version of DDT was developed at MIT for the PDP-1 computer in 1961, but newer versions on newer platforms continued to use the same name. After being ported to other vendor's platforms and changing media, the name was changed to the less DEC-centric version.

A debugger is a computer program that is used to debug (and sometimes test or optimize) other programs which might be running on the same computer (host computer) as the debugger is running, might be running on the target hardware, or might be running on the ISS.
Debuggers make the debugging process much easier and faster, to the point where the availability of a good one for a particular language and platform can sway the decision to use that language rather than another language that is superior in other respects but lacks such tools.
