    • SIMD (Single Instruction Multiple Data)

      SIMD (Single Instruction Multiple Data)

      SIMD (Single Instruction Multiple Data) is a computer science method of combining multiple operations into a single computer instruction. The total number of operations combined is normally a factor of the power of two. The employment of SIMD results in significant savings in speed for algorithms designed to work in parallel. The technology is used

Biology of a Fingerprint Every person has marks on his fingers. These marks

    • Unbuffered Memory

      Unbuffered Memory

      Unbuffered memory, or unregistered memory, is memory in which no hardware register exists between a RAM chip and a memory controller. Unbuffered memory is not as stable as buffered memory, but is faster and cheaper to implement. While buffered memory may be necessary in some computer systems, such as high-end corporate servers and workstations, where
