Framebuffer. A framebuffer ( frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. [2] Modern video cards contain framebuffer circuitry in their cores.
Ethernet flow control. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion . The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.
An aperture card is a type of punched card with a cut-out window into which a chip of microfilm is mounted. Such a card is used for archiving or for making multiple inexpensive copies of a document for ease of distribution. The card is typically punched with machine-readable metadata associated with the microfilm image, and printed across the ...
Multiple buffering. Sets 1, 2 and 3 represent the operation of single, double and triple buffering, respectively, with vertical synchronization (vsync) enabled. In each graph, time flows from left to right. Note that 3 shows a swap chain with three buffers; the original definition of triple buffering would throw away frame C as soon as frame D ...
Ethernet frame illustrating variable-length payload. Jumbo frames have payloads greater than 1500 bytes. In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard. [1] The payload limit for jumbo frames is variable: while 9000 bytes is the most commonly used limit ...

A Windows accelerator was a type of Graphics processing unit for personal computers with additional acceleration features like 2D line-drawings, blitter, clipping, font caching, hardware cursor support, color expansion, linear addressing, and pattern, polygon and area fills. [1] The functionality marketed for accelerating the Microsoft Windows ...
A window sill in the most general sense is a horizontal structural element below a window opening or window unit in masonry construction or framed construction and is regarded as part of the window frame. The bottom of a window frame sits on top of the window sill of the wall opening. A window sill may span the entire width of a wall from ...
