GDI

G raphics D evice I nterfaces link graphics hardware devices with the CPU. Much of the power of graphics processing depends upon whether the system has 8-bit, 16-bit, 32-bit, or 64-bit graphics power. Limitations of customer hardware often detract from the ability to develop operating systems to take full advantage of graphics power. For example, when developing Windows Chicago for 32-bit processors, Microsoft Corporation had to leave 16-bit GDI capacity on its 32-bit operating system.
