Cyclic redundancy check. 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.
Computation of a cyclic redundancy check is derived from the mathematics of polynomial division, modulo two. In practice, it resembles long division of the binary message string, with a fixed number of zeroes appended, by the "generator polynomial" string except that exclusive or operations replace subtractions.
Key size. In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher ). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by ...
Pocket PC 2002. v. t. e. Microsoft Windows XP Professional x64 Edition is an edition of Windows XP for x86-64 personal computers. It was released on April 25, 2005, around the same time as with the x86-64 versions of Windows Server 2003. It is designed to use the expanded 64-bit memory address space provided by the x86-64 architecture.
256 bits is a common key size for symmetric ciphers in cryptography, such as Advanced Encryption Standard (AES). Increasing the word size can accelerate multiple precision mathematical libraries. Applications include cryptography. Researchers at the University of Cambridge use a 256-bit capability pointer, which includes capability and ...
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. [1] [2] Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle.
PureBasic IDE 5.10. PureBasic is a commercially distributed procedural computer programming language and integrated development environment based on BASIC and developed by Fantaisie Software for Windows, Linux, and macOS. An Amiga version is available, although it has been discontinued and some parts of it are released as open-source.
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP. The first Itanium processor, codenamed Merced, was released in 2001.
