WGU C952 Terms to Know, Exam Questions and answers, graded A+ SISD - -Single Instruction Single Data; uniprocessor SIMD - -Same Instruction Many Data streams MIMD - -Many Instructions Many Data streams SPMD - -Single Program, multiple data streams DRAM - -Dynamic random access memory: memory built as chip. Random access to any location. SRAM - -Static Random Access Memory: memory built as chip, faster and less dense than DRAM Spatial locality - -locality principle stating that if data location is referenced, data locations with nearby addresses will tend to referenced soon Temporal locality - -local principle stating data location is referenced then it will tend to be referenced again soon Superscalar - -advanced pipeline technique that enables the processor to execute more than one instruction per clock cycle by selecting them during execution Amdahl's Law - -performance enhancement possible with given improvement is limited by amount the improved feature is used. Weak Scaling - -speed up achieved while increasing the size of the problem proportionally to the increase in # of processors Strong Scaling - -speed up achieved without increasing size of problem TLB - -Translation-Lookaside Buffer: cache that keeps track of recently used address mappings to avoid an access to the page table Parallelization - -computing operations in parallel
