WGU C952 Terms to Know (All Correct)

SISD correct answers Single Instruction Single Data; uniprocessor SIMD correct answers Same Instruction Many Data streams MIMD correct answers Many Instructions Many Data streams SPMD correct answers Single Program, multiple data streams DRAM correct answers Dynamic random access memory: memory built as chip. Random access to any location. SRAM correct answers Static Random Access Memory: memory built as chip, faster and less dense than DRAM Spatial locality correct answers locality principle stating that if data location is referenced, data locations with nearby addresses will tend to referenced soon Temporal locality correct answers local principle stating data location is referenced then it will tend to be referenced again soon Superscalar correct answers advanced pipeline technique that enables the processor to execute more than one instruction per clock cycle by selecting them during execution Amdahl's Law correct answers performance enhancement possible with given improvement is limited by amount the improved feature is used. Weak Scaling correct answers speed up achieved while increasing the size of the problem proportionally to the increase in # of processors Strong Scaling correct answers speed up achieved without increasing size of problem TLB correct answers Translation-Lookaside Buffer: cache that keeps track of recently used address mappings to avoid an access to the page table Parallelization correct answers computing operations in parallel Pipelining correct answers technique where multiple instructions are overlapping in execution, think assemble line Memory correct answers storage area in which programs are kept while running and contains data needed to run programs Control correct answers component of processor that commands datapath, memory, I/O devices according to instructions of program.
