  2. gzip - Wikipedia

    en.wikipedia.org/wiki/Gzip

    gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of the compress utility and other popular archivers. "gzip" is often also used to refer to the gzip file format ...

    Linux, macOS, Windows Genozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others. [4].gz application/gzip [5] gzip: Unix-like GNU Zip, the primary compression format used by Unix-like systems. The compression algorithm is Deflate, which combines LZSS with Huffman coding. .lz application/x-lzip lzip: Unix-like

  4. zlib - Wikipedia

    en.wikipedia.org/wiki/Zlib

    zlib (/ ˈ z iː l ɪ b / or "zeta-lib", / ˈ z iː t ə ˌ l ɪ b /) [2] [3] is a software library used for data compression as well as a data format. [4] zlib was written by Jean-loup Gailly and Mark Adler and is an abstraction of the DEFLATE compression algorithm used in their gzip file compression program. zlib is also a crucial component of many software platforms, including Linux, macOS ...

  5. Solid compression - Wikipedia

    en.wikipedia.org/wiki/Solid_compression

    A tar.gz is created by joining the files in tar and then compressing with gzip. In computing, solid compression is a method for data compression of multiple files, wherein all the uncompressed files are concatenated and treated as a single data block. Such an archive is called a solid archive.

  6. Deflate - Wikipedia

    en.wikipedia.org/wiki/DEFLATE

    The zlib/gzip reference implementation allows the user to select from a sliding scale of likely resulting compression-level vs. speed of encoding. Options range from 0 (do not attempt compression, just store uncompressed) to 9 representing the maximum capability of the reference implementation in zlib/gzip.

  7. Position-independent code - Wikipedia

    en.wikipedia.org/wiki/Position-independent_code

    By way of comparison, on early segmented systems such as Burroughs MCP on the Burroughs B5000 (1961) and Multics (1964), and on paging systems such as IBM TSS/360 (1967) [c], code was also inherently position-independent, since subroutine virtual addresses in a program were located in private data external to the code, e.g., program reference ...

    Cabinet files are used to organize installation files that are copied to the user's system. [2] C4 – JEDMICS image files, a DOD system; CALS – JEDMICS image files, a DOD system; XAML – Used in programs like Visual Studio to create exe files. CPT, SEA – Compact Pro ; CS – File extension for C-Sharp (C#) files

  9. vmlinux - Wikipedia

    en.wikipedia.org/wiki/Vmlinux

    The bzImage was compressed using gzip until Linux 2.6.30, [3] which introduced more algorithms. Although the bz prefix may suggest that bzip2 compression is used, this is not the case. [1] (The bzip2 package is often distributed with tools prefixed with bz, such as bzless, bzcat, etc.) The bzImage file is in a specific format.
