WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
The VGA text buffer is located at physical memory address 0xB8000. [14] Since this address is usually used by 16-bit x86 processes operating in real-mode, it is also the first half of memory segment 0xB800. The text buffer data can be read and written, and bitwise operations can be applied. A part of text buffer memory above the scope of the ...
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
GDI was present in the initial release of Windows. MS-DOS programs had manipulated the graphics hardware using software interrupts (sometimes via the Video BIOS) and by manipulating video memory directly. Code written in this way expects that it is the only user of the video memory, which was not tenable on multi-tasked environment, such as ...
If your contacts are getting emails you didn't send, your sent folder is full of messages you didn't send, or you're missing folders, it could be a sign that your account has been compromised or hacked. If you notice these signs, you may also end up having problems with sending or composing mail.
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.

A frame buffer may be designed with enough memory to store two frames worth of video data. In a technique known generally as double buffering or more specifically as page flipping, the framebuffer uses half of its memory to display the current frame. While that memory is being displayed, the other half of memory is filled with data for the next ...
