LZX (algorithm)
LZX is an LZ77 family compression algorithm, a slightly improved version of DEFLATE. imlib: the open source Windows Imaging (WIM) library - Compression algorithm https://wimlib.net/compression.html/ref> It is also the name of a file archiver with the same name. Both were invented by Jonathan Forbes and Tomi Poutanen in the 1990s. Instances of use of the LZX algorithm Amiga LZX LZX was publicly released as an Amiga file archiver in 1995, while the authors were studying at the University of Waterloo in Canada. The software was shareware, which was common for compression software at the time. The registered version contained fixes and improvements that were not available in the evaluation version. In 1997, the authors gave away a free keyfile, which allowed anyone to use the registered version, as they had stopped work on the archiver and stopped accepting registrations. Microsoft Cabinet files In 1996, Forbes went to work for Microsoft, and Microsoft's cabinet archiver was enha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LZ77
LZ77 and LZ78 are the two lossless data compression algorithms published in papers by Abraham Lempel and Jacob Ziv in 1977 and 1978. They are also known as Lempel-Ziv 1 (LZ1) and Lempel-Ziv 2 (LZ2) respectively. These two algorithms form the basis for many variations including Lempel–Ziv–Welch, LZW, Lempel–Ziv–Storer–Szymanski, LZSS, Lempel–Ziv–Markov chain algorithm, LZMA and others. Besides their academic influence, these algorithms formed the basis of several ubiquitous compression schemes, including GIF and the DEFLATE algorithm used in Portable Network Graphics, PNG and Zip (file format), ZIP. They are both theoretically dictionary coders. LZ77 maintains a sliding window during compression. This was later shown to be equivalent to the ''explicit dictionary'' constructed by LZ78—however, they are only equivalent when the entire data is intended to be decompressed. Since LZ77 encodes and decodes from a sliding window over previously seen characters, decompressio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
80x86
x86 (also known as 80x86 or the 8086 family) is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088. The 8086 was introduced in 1978 as a fully 16-bit extension of 8-bit Intel's 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486. Colloquially, their names were "186", "286", "386" and "486". The term is not synonymous with IBM PC compatibility, as this implies a multitude of other computer hardware. Embedded systems and general-purpose computers used x86 chips before the PC-compatible market started, some of them before the IBM PC (1981) debut. , most desktop and laptop computers sold are based on the x86 ar ...

Comparison Of File Archivers
The following tables compare general and technical information for a number of file archivers. Please see the individual products' articles for further information. They are neither all-inclusive nor are some entries necessarily up to date. Unless otherwise specified in the footnotes section, comparisons are based on the stable versions—''without'' add-ons, extensions or external programs. General information Basic general information about the archivers. Legend: Notes: Operating system support The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI ''Archive manager,'' for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the ''native program''. This is presumably a "compatibility layer." Notes: Archiver features Information about what common archiver features are implemented natively (without third-par ...

List Of Archive Formats
This is a list of file formats used by file archiver, archivers and data compression, compressors used to create Archive file, archive files. Archive formats by purpose Archive formats are used for backups, mobility, and archiving. Many archive formats data compression, compress the data to consume less storage space and result in quicker transfer times as the same data is represented by fewer bytes. Another benefit is that files are combined into one archive file which has less overhead for managing or transferring. There are numerous compression algorithms available to losslessly compress archived data; some algorithms are designed to work better (smaller archive or faster compression) with particular data types. Archive formats are used by Unix-like operating system, most operating systems to package (package management system), package software for easier distribution and installation than binary Executable and Linkable Format, executables.

XAD (software)
The XAD system is an open-source client-based unarchiving system for the Amiga. This means there is a master library called ''xadmaster.library'' which provides an interface between the client and the user application and there are clients handling the special archive formats. Three different types to handle file and disk archives and also disk image files (filesystem) are possible. They can be made by anyone. The master library itself includes some of these clients internally to make the work somewhat easier for the package maintainer and the user installing it. The XAD subsystem was officially included in AmigaOS 3.9 along with a simple ReAction GUI-based tool for unarchiving supported file archives. It is also part of MorphOS since version 2.0. The Mac OS X frontend is called The Unarchiver and written in Objective-C.

Xbox Live Avatars
Xbox Avatars are avatars and characters that represent users of the Xbox network (formerly known as Xbox Live) on the Xbox 360, Xbox One, and Xbox Series X and Series S video game consoles, Windows 10, and Windows 10 Mobile. Avatars originally debuted on the Xbox 360 as part of the "New Xbox Experience" system update released on November 19, 2008, updated on Xbox One with "New Xbox One Experience" Xbox One System Software on November 12, 2015, and reimagined with the release of the next generation character for Xbox One on October 11, 2018. The "Next generation" Avatar On June 13, 2017, during E3 2017, Microsoft announced a complete overhaul of the Avatars, providing a much greater emphasis of customization and inclusiveness, especially by adding limb customization, clothing that supported all characters – as the old system had different clothing for male and female body types – and support for changing asset color at runtime. Other customization includes cloth and hair th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NTFS
NT File System (NTFS) (commonly called ''New Technology File System'') is a proprietary journaling file system developed by Microsoft in the 1990s. It was developed to overcome scalability, security and other limitations with File Allocation Table, FAT. NTFS adds several features that File Allocation Table, FAT and HPFS (file system), HPFS lack, including: access control lists (ACLs); filesystem encryption; transparent compression; sparse files; Journaling file system, file system journaling and shadow copy, volume shadow copy, a feature that allows backups of a system while in use. Starting with Windows NT 3.1, it is the default file system of the Windows NT family superseding the File Allocation Table (FAT) file system. NTFS read/write support is available on Linux and Berkeley Software Distribution, BSD using NTFS3 in Linux kernel, Linux and NTFS-3G in BSD. NTFS uses several files hidden from the user to store metadata about other files stored on the drive which can help impr ...
