Graphics Device Interface

The Graphics Device Interface (GDI) is a core component of Windows operating systems that manages how images, text, and graphics are displayed on your screen and sent to printers. It acts as a bridge between software applications and hardware devices, translating drawing commands into signals that hardware can understand. Essentially, GDI enables applications to create and manipulate visual content consistently across different hardware, ensuring that what you see on your screen or printout appears correctly and smoothly.
