Short for National Television System Committee. The NTSC is responsible for setting television and video standards in the United States (in Europe and the rest of the world, the dominant television standards are PAL and SECAM). The NTSC standard for television defines a composite video signal with a refresh rate of 60 half-frames(interlaced) per second. Each frame contains 525 lines and can contain 16 million different colors.
The NTSC standard is incompatible with most computer video standards, which generally use RGB video signals. However, you can insert special video adapters into your computer that convertNTSC signals into computer video signals and vice versa.
(pronounced as separate letters) Short for network termination unit, a device that connects the PSTN with a CPE. This device marks the final interconnect between the public network and a customer��s private equipment. The NTU is owned by the service provider and typically has communication standards, such as voltages and protocols, that allow specific types […]
The NT Virtual DOS Machine (a.k.a WOW, or Windows on Windows), is a Win16 subsystem that runs under Windows NT, which allows 16-bit applications to run as if they were being executed on a DOS machine, with that machine’s multitasking and segmented memory model. Because the system is multitasked 16-bit DOS and Windows applications cannot […]
In X.25 communications, it is the X.121 address containing up to 15 binary code digits. [Source: National Center for Supercomputing Applications]
Short for Non-Uniform Memory Access, a type of parallel processing architecture in which each processor has its own local memory but can also access memory owned by other processors. It’s called non-uniform because the memory access times are faster when a processor accesses its own memory than when it borrows memory from another processor. NUMA […]
Short for Non-Uniform Rational B-Spline, a mathematical representation of a 3-dimensional object. Most CAD/CAM applications support NURBS, which can be used to represent analytic shapes, such as cones, as well as free-form shapes, such as car bodies.
