  2. 802.11 frame types - Wikipedia

    en.wikipedia.org/wiki/802.11_Frame_Types

    Generic 802.11 Frame. The very first two octets transmitted by a station are the Frame Control. The first three subfields within the frame control and the last field are always present in all types of 802.11 frames. These three subfields consist of two bits Protocol Version subfield, two bits Type subfield, and four bits Subtype subfield.

  3. Frame synchronization - Wikipedia

    en.wikipedia.org/wiki/Frame_synchronization

    In telecommunications, frame synchronization or framing is the process by which, while receiving a stream of fixed-length frames, the receiver identifies the frame boundaries, permitting the data bits within the frame to be extracted for decoding or retransmission.

  4. Fibre Channel frame - Wikipedia

    en.wikipedia.org/wiki/Fibre_channel_frame

    The primary function of the Fabric is to receive the frames from the source port and route them to the destination port. It is the FC-2 layer's responsibility to break the data to be transmitted into frame size, and reassemble the frames. Each frame begins and ends with a frame delimiter. The frame header immediately follows the Start of Frame ...

  5. LZ77 and LZ78 - Wikipedia

    en.wikipedia.org/wiki/LZ77_and_LZ78

    If two successive characters in the input stream could be encoded only as literals, the length of the length–distance pair would be 0. LZSS improves on LZ77 by using a 1-bit flag to indicate whether the next chunk of data is a literal or a length–distance pair, and using literals if a length–distance pair would be longer.

  6. Ethernet frame - Wikipedia

    en.wikipedia.org/wiki/Ethernet_frame

    Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport

  7. Video compression picture types - Wikipedia

    en.wikipedia.org/wiki/Video_compression_picture...

    Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame. For example, in a scene where a car moves across a stationary background, only the ...

  8. AoS and SoA - Wikipedia

    en.wikipedia.org/wiki/AOS_and_SOA

    Structure of arrays (SoA) is a layout separating elements of a record (or 'struct' in the C programming language) into one parallel array per field. [1] The motivation is easier manipulation with packed SIMD instructions in most instruction set architectures, since a single SIMD register can load homogeneous data, possibly transferred by a wide internal datapath (e.g. 128-bit).

  9. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    In inter-frame coding, individual frames of a video sequence are compared from one frame to the next, and the video compression codec records the differences to the reference frame. If the frame contains areas where nothing has moved, the system can simply issue a short command that copies that part of the previous frame into the next one.
