  2. Bit array - Wikipedia

    en.wikipedia.org/wiki/Bit_array

    A bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.

  3. ZPAQ - Wikipedia

    en.wikipedia.org/wiki/ZPAQ

    The beginning of H forms the array of contexts. An assembly language-like program is called once for each coded or decoded byte with that byte as input in A. The final context seen by the COMP section is the computed context combined with the previously seen bits of the current byte.

  4. Stack buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Stack_buffer_overflow

    In figure C above, when an argument larger than 11 bytes is supplied on the command line foo() overwrites local stack data, the saved frame pointer, and most importantly, the return address. When foo() returns, it pops the return address off the stack and jumps to that address (i.e. starts executing instructions from that address).

  5. LZ4 (compression algorithm) - Wikipedia

    en.wikipedia.org/wiki/LZ4_(compression_algorithm)

    Each sequence begins with a one-byte token that is broken into two 4-bit fields. The first field represents the number of literal bytes that are to be copied to the output. The second field represents the number of bytes to copy from the already decoded output buffer (with 0 representing the minimum match length of 4 bytes).

  6. Fletcher's checksum - Wikipedia

    en.wikipedia.org/wiki/Fletcher's_checksum

    An ordering problem that is easy to envision occurs when the data word is transferred byte-by-byte between a big-endian system and a little-endian system and the Fletcher-32 checksum is computed. If blocks are extracted from the data word in memory by a simple read of a 16-bit unsigned integer, then the values of the blocks will be different in ...

  7. Serialization - Wikipedia

    en.wikipedia.org/wiki/Serialization

    Flow diagram. In computing, serialization (or serialisation, also referred to as pickling in Python) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer ...

  8. Action Message Format - Wikipedia

    en.wikipedia.org/wiki/Action_Message_Format

    The byte following the string marker is no longer denoting pure length but it is a complex byte where the least significant bit indicated whether the string is 'inline' (1) i.e. not in the array or 'reference' (0) in which case the index of the array is saved. The table includes keys as well as values.

  9. Smalltalk - Wikipedia

    en.wikipedia.org/wiki/Smalltalk

    defines a seven element array whose first element is a literal array, second element a byte array, third element the string 'four', and so on. Many implementations support the following literal syntax for ByteArrays: #
