DirectInput. In computing, DirectInput is a legacy [1] Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, or a gamepad. It also provides a system for action mapping, which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
DirectX. Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth.
Linux. Device Mapper Multipath Input Output often shortened to DM-Multipathing and abbreviated as DM-MPIO provides input-output ( I/O) fail-over and load-balancing by using multipath I/O within Linux for block devices. [1] [2] [3] By utilizing device-mapper, the multipathd daemon provides the host-side logic to use multiple paths of a redundant ...
KMixer is the Kernel Audio Mixer driver, a part of WDM Audio in Windows 98 to Windows XP which handles the mixing of multiple sound buffers into an output. The tasks performed by KMixer.sys: Mixing multiple PCM audio streams. Format, bit-depth (also known as word-length) and sample-rate conversion.
In computing, an input–output memory management unit ( IOMMU) is a memory management unit (MMU) connecting a direct-memory-access –capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses (also called ...
Device mapper. The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots. [1]
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel, distributed algorithm on a cluster.. A MapReduce program is composed of a map procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a reduce method, which performs a summary operation (such as ...
In computing and data management, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks, including: [1] Data transformation or data mediation between a data source and a destination. Identification of data relationships as ...
