If the channel characteristics cannot be determined, or are highly variable, an error-detection scheme may be combined with a system for retransmissions of erroneous data. This is known as automatic repeat request (ARQ), and is most notably used in the Internet.
Data degradation is the gradual corruption of computer data due to an accumulation of non-critical failures in a data storage device.It is also referred to as data decay, data rot or bit rot. [1]
Typically it attaches to the memory card slot of the system, with the disc based software refusing to work if the dongle is not detected. The dongle is also used for holding settings and storage of new codes, added either by the user or through official updates, because the disc, being read only, cannot store them.
STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
Windows successfully loaded the device driver for this hardware but cannot find the hardware device. 42: Windows cannot run the driver for this device because there is a duplicate device already running in the system. 43: Windows has stopped this device because it has reported problems. 44: An application or service has shut down this hardware ...
FPM, EDO, SDR, and RDRAM memory was not commonly installed in a dual-channel configuration. DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given ...
Starting in VBE/Core 2.0, VESA no longer defines new VESA mode numbers and no longer requires a device to implement the old numbers. To properly detect information of a screen mode, use Function 01h - Return VBE Mode Information. Mode 81FFh is a special video mode designed to preserve current memory contents and give access to the entire video ...
This protocol allows an SD-SDI receiver to verify that each field of video is received correctly. The SD-SDI transmitter calculates two CRC values for each video field—one corresponding to the active picture, and corresponding to the entire field (excluding the switching lines)--and places them in an EDH ancillary data packet. The EDH packet ...
