Disk Image Emulator
Virtual disk and virtual drive are software components that emulate an actual disk storage device. Virtual disks and virtual drives are common components of virtual machines in hardware virtualization, but they are also widely used for various purposes unrelated to virtualization, such as for the creation of logical disks,software development, testing environments, and data management. They offer flexibility, ease of management, and the ability to simulate different storage environments without needing physical hardware. Operation A virtual drive is a software component that emulates an actual disk drive, such as an optical disc drive, a floppy disk drive, or a hard disk drive. To other programs, a virtual drive looks and behaves like an actual physical device. A virtual disk may be in any of the following forms: * Disk image, a computer file that contains the exact data structure of an actual storage device * Logical disk (also known as vdisk), an array of two or more actu ...

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because a significant amount of software is written specifically for HP models. If a non-HP printer emulates an HP printer, any software designed for an actual HP printer will also function on the non-HP device, producing equivalent print results. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is in ...

File Server
In computing, a file server (or fileserver) is a computer attached to a network that provides a location for shared disk access, i.e. storage of computer files (such as text, image, sound, video) that can be accessed by workstations within a computer network. The term server highlights the role of the machine in the traditional client–server scheme, where the clients are the workstations using the storage. A file server does not normally perform computational tasks or run programs on behalf of its client workstations (in other words, it is different from e.g. an application server, which is another type of server). File servers are commonly found in schools and offices, where users use a local area network to connect their client computers. Types of file servers A file server may be dedicated or non-dedicated. A dedicated server is designed specifically for use as a file server, with workstations attached for reading and writing files and databases. File servers may also b ...

Removable Media
In computing, a removable media is a data storage media that is designed to be readily inserted and removed from a system. Most early removable media, such as floppy disks and optical discs, require a dedicated read/write device (i.e. a drive) to be installed in the computer, while others, such as USB flash drives, are plug-and-play with all the hardware required to read them built into the device, so only need a driver software to be installed in order to communicate with the device. Some removable media readers/drives are integrated into the computer case, while others are standalone devices that need to be additionally installed or connected. Examples of removable media that require a dedicated reader drive include: * Optical discs, e.g. Blu-rays (both standard and UHD versions), DVDs, CDs * Flash memory-based memory cards, e.g. CompactFlash, Secure Digital, Memory Stick * Magnetic storage media ** Floppy and Zip disks (now obsolete) ** Disk packs (now obsolete) ...

Floating Drive
In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volumes. Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree" (or, for non-hierarchical file systems, an independent list of files). Origin The concept of drive letters, as used today, presumably owes its origins to IBM's VM family of operating systems, dating back to CP/CMS in 1967 (and its research predecessor CP-40), by way of Digital Research's (DRI) CP/M. The concept evolved through several steps: * CP/CMS uses drive letters to identify '' minidisks'' attached to a user session. A full file reference (''pathname'' in today's parlance) consists of a ''filename'', a ''file ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Product Activation
Product activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it ''determines'' whether it is authorized to fully function. Activation allows the software to stop blocking its use. An activation can last "forever", or it can have a time limit, requiring a renewal or re-activation for continued use. Product activation is often based on verification of a product key, which is a sequence of letters and/or numbers that is verified via an algorithm or mathematical formula, for a particular solution or set of solutions, possibly combined with verification in a database or some other method for verification which can be done via the internet. If the solution matches expectations, and verification confirms that the product key is genuine, the product is activated. Using hashing, it is possible to represent letters as num ...

Computer Game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, controller, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and computer games (which includes LAN games, online games, and browser games). More recently, the video game industry h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Piracy
Online piracy or software piracy is the practice of downloading and distributing copyrighted works digitally without permission, such as music, movies or software. History Nathan Fisk traces the origins of modern online piracy back to similar problems posed by the advent of the printing press. Quoting from legal standards in '' MGM Studios, Inc. v. Grokster, Ltd.'', he notes that there have historically been a number of technologies which have had a "dual effect" of facilitating legitimate sharing of information, but which also facilitate the ease with which copyright can be violated. He likens online piracy to issues faced in the early 20th century by stationers in England, who tried and failed to prevent the large scale printing and distribution of illicit sheet music. WordStar was so widely pirated that many books on how to use the software appeared, their authors knowing that they were selling documentation for illicit copies. Starting in the 1980s, the availability of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format co-developed by Philips and Sony to store and play digital audio recordings. It employs the Compact Disc Digital Audio (CD-DA) standard and was capable of holding of uncompressed stereo audio. First released in Japan in October 1982, the CD was the second optical disc format to reach the market, following the larger LaserDisc (LD). In later years, the technology was adapted for computer data storage as CD-ROM and subsequently expanded into various writable and multimedia formats. , over 200 billion CDs (including audio CDs, CD-ROMs, and CD-Rs) had been sold worldwide. Standard CDs have a diameter of and typically hold up to 74 minutes of audio or approximately of data. This was later regularly extended to 80 minutes or by reducing the spacing between data tracks, with some discs unofficially reaching up to 99 minutes or which falls outside established specifications. Smaller variants, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Booting
Network booting, shortened netboot, is the process of booting a computer from a computer network, network rather than a local drive. This method of booting can be used by Router (computing), routers, diskless workstations and centrally managed computers (thin clients) such as public computers at library, libraries and schools. Network booting can be used to centralize management of disk storage, which supporters claim can result in reduced capital and maintenance costs. It can also be used in Computer cluster, cluster computing, in which Node (networking), nodes may not have local disks. In the late 1980s/early 1990s, network boot was used to save the expense of a disk drive, because a decently sized harddisk would still cost thousands of dollars, often equaling the price of the Central processing unit, CPU. Hardware support Contemporary desktop computer, desktop IBM PC compatible, personal computers generally provide an option to boot from the network in their BIOS/UEFI via th ...

Booting
In computing, booting is the process of starting a computer as initiated via Computer hardware, hardware such as a physical button on the computer or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system. On some systems a power-on reset (POR) does not initiate booting and the operator must initiate booting after POR completes. IBM uses the term Initial Program Load (IPL) on someE.g., System/360 through IBM Z, RS/6000 and System/38 through IBM Power Systems product lines. Restarting a computer also is called Reboot (computing), ''rebooting'', which can be "hard", e.g. after electrical power to the CPU is switched from off to on, or "soft", where the power is not cut. On some systems, a soft boot may optionally clear RAM to zero. Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
