Sound Blaster
Sound Blaster is a family of sound cards and audio peripherals designed by Creative Technology, Creative Technology/Creative Labs of Singapore. The first Sound Blaster card was introduced in 1989. Sound Blaster sound cards were the de facto standard for consumer audio on the IBM PC compatible system platform, platform until the widespread transition to Microsoft Windows 95 and the integration of commoditized audio electronics in PCs. Windows 95 standardized the programming interface at the application level and thereby eliminated the importance of backward compatibility with Sound Blaster cards. By 1995, Sound Blaster cards had sold over 15 million units worldwide and accounted for seven out of ten sound card sales. To date, Sound Blaster has sold over 400 million units, and their current product lineup includes USB-powered Digital-to-analog converter, DACs as well as other audio adapters.

Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

MPU-401
The MPU-401, where ''MPU'' stands for MIDI Processing Unit, is an important but now obsolete interface for connecting MIDI-equipped electronic music hardware to personal computers. It was designed by Roland Corporation, which also co-authored the MIDI standard. Design Released around 1984, the original MPU-401 was an external breakout box providing MIDI IN/MIDI OUT/MIDI THRU/TAPE IN/TAPE OUT/MIDI SYNC connectors, for use with a separately-sold interface card/cartridge ("MPU-401 interface kit") inserted into a computer system. For this setup, the following "interface kits" were made: * MIF-APL: For the Apple II * MIF-C64: For the Commodore 64 * MIF-FM7: For the Fujitsu FM-7 * MIF-IPC: For the IBM Personal Computer, IBM PC/IBM Personal Computer XT, IBM XT. It turned out not to work reliably with 286 and faster processors. Early versions of the actual PCB had IF-MIDI/IBM as a silk screen. * MIF-IPC-A: For the IBM Personal Computer AT, IBM AT, works with PC and XT as well. * Xanadu ...

DOS Protected Mode Interface
In computing, the DOS Protected Mode Interface (DPMI) is a specification introduced in 1989 which allows a DOS program to run in protected mode, giving access to many features of the new PC processors of the time not available in real mode. It was initially developed by Microsoft for Windows 3.0, although Microsoft later turned control of the specification over to an industry committee with open membership. Almost all modern DOS extenders are based on DPMI and allow DOS programs to address all memory available in the PC and to run in protected mode (mostly in ring (computer security), ring 3, least privileged). Overview DPMI stands for DOS Protected Mode Interface. It is an API that allows a program to run in protected mode on 80286 series and later processors, and do the calls to real mode without having to set up these CPU modes manually. DPMI also provides the functions for managing various resources, notably Computer Memory, memory. This allows the DPMI-enabled programs to ...

Hardware-assisted Virtualization
In computing, virtualization (abbreviated v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. Virtualization began in the 1960s with IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the '' host machine'' is the machine that is used by the virtualization and the ''guest machine'' is the virtual machine. The words ''host'' and ''guest'' are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a '' hypervisor'' or ''virtual machine monitor''. Hardware virtualization is not the same as hardware emulation. Hardware-assisted virtualization facilitates building a virtual machine monitor and allows guest OSes to be run in isolation. Deskto ...

NTVDM
Virtual DOS machines (VDM) refer to a technology that allows running 16-bit/32-bit DOS and 16-bit Windows programs when there is already another operating system running and controlling the hardware. Overview Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions). The operating system can then perform an emulation and resume the execution of the DOS software. VDMs generally also implement support for running 16-bit and 32-bit protected mode software ( DOS extenders), which has to conform to the DOS Protected Mode Interface (DPMI). When a DOS program running inside a VDM needs to access a peripheral, Windows will either allow this di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOSBox
DOSBox is a free and open-source MS-DOS emulator. It supports running programs primarily video games that are otherwise inaccessible since hardware for running a compatible disk operating system (DOS) is obsolete and generally unavailable today. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is relatively widespread; partially driven by its use in commercial re-releases of games. Development Before Windows XP, consumer-oriented versions of Windows were based on MS-DOS. Windows 3.0 and its updates were operating environments that ran on top of MS-DOS, and the Windows 9x series consisted of operating systems that were still based on MS-DOS. These versions of Windows could run DOS applications. Conversely, the Windows NT operating systems were not based on DOS. A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Althou ...

Shell Extension
File Explorer, previously known as Windows Explorer, is a file manager application and default desktop environment that is included with releases of the Microsoft Windows operating system from Windows 95 onwards. It provides a graphical user interface for accessing the file systems, as well as user interface elements such as the taskbar and desktop environment, desktop. The application was renamed from "Windows Explorer" to "File Explorer" in Windows 8; however, the old name of "Windows Explorer" can still be seen in the Task Manager (Windows), Windows Task Manager. Overview Windows Explorer was first included with Windows 95 as a replacement for File Manager (Windows), File Manager, which came with all versions of Windows 3.x operating systems. Explorer could be accessed by double-clicking the new My Computer desktop icon or launched from the new Start Menu that replaced the earlier Program Manager. There is also a shortcut key combination: . Successive versions of Windows ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wizard (software)
A software wizard or setup assistant or multi-step form is a user interface that leads a user through a sequence of small steps, such as a dialog box to configure a program for the first time. They are used to make complex, unfamiliar tasks easier by breaking them into smaller pieces. History Before the 1990s, "wizard" was a common term for a technical expert, comparable to "hacker." The 1985 textbook Structure and Interpretation of Computer Programs was nicknamed the "Wizard Book" for the illustration on its cover; its first chapter says, "A computational process is indeed much like a sorcerer's idea of a spirit." When developing the first version of its desktop publishing software, Microsoft Publisher, around 1991, Microsoft wanted to help users create well-presented documents in spite of their lack of graphic design skills. Microsoft reasoned that, no matter the tools a program offered, users would not know how best to use them. Publisher's "Page Wizards" instead provided a s ...

Flight Simulation
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities. The term "flight simulator" may carry slightly different meaning in general language and technical documents. In past regulations, it referred specifically to devices which can closely mimic the behavior of aircraft throughout various procedures and flight conditions. In more recent definitions, this has been named "full fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
