"设备描述表" can be translated as "Device Context" or more specifically in programming contexts, especially related to Windows Graphics Device Interface (GDI), as "Device Context (DC)".
Device Context is a general term used in computing to refer to a data structure that contains information about the device (such as a display, printer, or plotter) and its attributes, which is used for drawing operations.
In Windows programming, Device Context (DC) is a fundamental concept in GDI, representing a device-independent drawing surface. It encapsulates the necessary information for drawing on a specific device, such as a screen or a printer.
