DC

DC

1. Direct Current. Electrical current that flows in a single direction only, cf AC.

2. Domain Controller.

3. Device Context. In the Windows GDI library, a device context is a handle used for drawing onto a device. Each device context is created for a specific device, for example a display, a printer, plotter, bitmap etc. Conceptually a DC can be thought of as a handle to a drawing surface, operations that work on the DC should therefore have no need to know the type of surface (be it a printer, bitmap etc).

Each Device Context will in turn have a number of other objects associated with it, such as pens, brushes and fonts.
