A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1][2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated ...
The software to generate the tables is so small and fast that it is usually faster to compute them on program startup than to load precomputed tables from storage. One popular technique is to use the bit-at-a-time code 256 times to generate the CRCs of the 256 possible 8-bit bytes.

If a hardware code page does not match one of those with official code page assignments, an arbitrary number from the range 57344–61439 (E000h–EFFFh) for user-definable code pages or 65280–65533 (FF00h–FFFDh) for private use code pages could be specified per IBM CDRA to give the operating system a non-conflictive "handle" to select that ...
The National Public Warning System, also known as the Primary Entry Point (PEP) stations, is a network of 77 radio stations that are, in coordination with FEMA, used to originate emergency alert and warning information to the public before, during, and after incidents and disasters.
When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite state machine is often generated instead of a deterministic one, because usually the former can be created more ...
Code page 1021 (CCSID 1021), [1] also known as CP1021 or CH7DEC, [2] is an IBM code page number assigned to the Swiss variant of DEC's National Replacement Character Set (NRCS). [3] [4] [5] The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation.
Code page 1104. Code page 1104 ( CCSID 1104), [ 1] also known as CP1104, [ 2] F7DEC, [ 3] ISO-IR-025 or NF Z 62-010 (1973)[ 4] is an IBM code page number assigned to the French variant of DEC 's National Replacement Character Set (NRCS). [ 5][ 6] The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 ...
