PearPC
PearPC is an architecture-independent PowerPC platform emulator capable of running many PowerPC operating systems, including pre-Intel versions of Mac OS X, Darwin and Linux. It is released under the terms of the GNU General Public License (GPL). It can be executed on Microsoft Windows, Linux, FreeBSD and other systems based on POSIX-X11. The first official release was made on May 10, 2004. The emulator features a just-in-time (JIT) processor emulation core which dynamically translates PPC code into x86 code, caching the results. Despite running only on x86 host architectures, the JIT emulation core runs at least 10 times as fast as the architecture-independent generic processor emulation core. However, according to the man pages supplied with Debian's packages of PearPC, even the JIT core runs around 40 times slower than the host machine would if executing native code. Until December 2005 PearPC advanced quickly in speed, stability and features. After that time, however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CherryOS
CherryOS was a PowerPC G4 processor emulator for x86 Microsoft Windows platforms, which allowed various Apple Inc. programs to be operated on Windows XP. Announced and made available for pre-orders on October 12, 2004, it was developed by Maui X-Stream (MXS), a startup company based in Lahaina, Hawaii and a subsidiary of Paradise Television. The program encountered a number of launch difficulties its first year, including a poorly-reviewed soft launch in October 2004, wherein ''Wired Magazine'' argued that CherryOS used code grafted directly from PearPC, an older open-source emulator. Lead developer Arben Kryeziu subsequently stated that PearPC had provided the inspiration for CherryOS, but "not the work, not the architecture. With their architecture I'd never get the speed." After further development, CherryOS 1.0 was released in its final form on March 8, 2005, with support for CD, DVD, USB, FireWire, and Ethernet. It was described as automatically detecting "hardware and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Debian
Debian (), also known as Debian GNU/Linux, is a Linux distribution composed of free and open-source software, developed by the community-supported Debian Project, which was established by Ian Murdock on August 16, 1993. The first version of Debian (0.01) was released on September 15, 1993, and its first stable version (1.1) was released on June 17, 1996. The Debian Stable branch is the most popular edition for personal computers and servers. Debian is also the basis for many other distributions, most notably Ubuntu. Debian is one of the oldest operating systems based on the Linux kernel. The project is coordinated over the Internet by a team of volunteers guided by the Debian Project Leader and three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines. New distributions are updated continually, and the next candidate is released after a time-based freeze. Since its founding, Debian has been developed openly ...

3Com
3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers. 3Com provided network interface controller and switches, routers, wireless access points and controllers, IP voice systems, and intrusion prevention systems. The company was based in Santa Clara, California. From its 2007 acquisition of 100 percent ownership of H3C Technologies Co., Limited (H3C) —initially a joint venture with China-based Huawei Technologies—3Com achieved a market presence in China, and a significant networking market share in Europe, Asia, and the Americas. 3Com products were sold under the brands 3Com, H3C, and TippingPoint ...

PowerPC G3
The PowerPC 7xx is a family of third generation 32-bit PowerPC microprocessors designed and manufactured by IBM and Motorola (spun off as Freescale Semiconductor bought by NXP Semiconductors). This family is called the PowerPC G3 by its well-known customer Apple Inc., which introduced it on November 10, 1997. The term "PowerPC G3" is often, and incorrectly, imagined to be a microprocessor when in fact a number of microprocessors from different vendors have been used. Such designations were applied to Macintosh computers such as the PowerBook G3, the IMac G3, multicolored iMacs, iBooks and several desktops, including both the Power Macintosh G3, Beige and Power Macintosh G3 (Blue & White), Blue and White Power Macintosh G3s. The low power requirements and small size made the processors ideal for laptops and the name lived out its last days at Apple in the iBook. The 7xx family is also widely used in embedded devices like printers, routers, storage devices, spacecraft, and video ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

OSx86
A Hackintosh (a portmanteau of "Hack" and "Macintosh") is a computer that runs Apple's Macintosh operating system macOS (formerly named "Mac OS X" or "OS X") on computer hardware not authorized for the purpose by Apple. This can also include running Macintosh software on hardware it is not originally authorized for. ''"Hackintoshing"'' began as a result of Apple's 2005 transition to Intel processors, away from PowerPC. Since 2005, Mac computers use the same x86-64 computer architecture as many other desktop PCs, laptops, and servers, meaning that in principle, the code making up macOS systems and software can be run on alternative platforms with minimal compatibility issues. Benefits cited for "Hackintoshing" can include cost (older, cheaper or commodity hardware), ease of repair and piecemeal upgrade, and freedom to use customized choices of components that are not available (or not available together) in the branded Apple products. macOS can also be run on several non-Apple v ...

ISO Image
An optical disc image (or ISO image, from the ISO 9660 file system used with CD-ROM media) is a disk image that contains everything that would be written to an optical disc, disk sector by disc sector, including the optical disc file system. ISO images are expected to contain the binary image of an optical media file system (usually ISO 9660 and its extensions or UDF), including the data in its files in binary format, copied exactly as they were stored on the disc. The data inside the ISO image will be structured according to the file system that was used on the optical disc from which it was created. ISO images can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format. And like any other ISO image, it may be written to an optical disc such as CD, DVD and Blu- ...

Apple Disk Image
Apple Disk Image is a disk image format commonly used by the macOS operating system. When opened, an Apple Disk Image is mounted as a volume within the Finder. An Apple Disk Image can be structured according to one of several proprietary disk image formats, including the Universal Disk Image Format (UDIF) from Mac OS X and the New Disk Image Format (NDIF) from Mac OS 9. An Apple disk image file's name usually has ".dmg" as its extension. A disk image is a compressed copy of the contents of a disk or folder. Disk images have .dmg at the end of their names. To see the contents of a disk image, you must first open the disk image so it appears on the desktop or in a Finder window. Features Apple Disk Image files are published with a MIME type of ''application/x-apple-diskimage''. Different file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems. Some of the file systems support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
64-bit
In computer architecture, 64-bit Integer (computer science), integers, memory addresses, or other Data (computing), data units are those that are 64 bits wide. Also, 64-bit central processing unit, CPUs and arithmetic logic unit, ALUs are those that are based on processor registers, address buses, or Bus (computing), data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all 0's or all 1's, and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer archit ...
