WGU C952 Computer Architecture Terms to Know During Final Exam Prepping WGU C952 Computer Architecture Terms to Know During Final Exam Prepping SISD << correct answer >> Single Instruction Single Data; uniprocessor SIMD << correct answer >> Same Instruction Many Data streams MIMD << correct answer >> Many Instructions Many Data streams SPMD << correct answer >> Single Program, multiple data streams DRAM << correct answer >> Dynamic random access memory: memory built as chip. Random access to any location. SRAM << correct answer >> Static Random Access Memory: memory built as chip, faster and less dense than DRAM Spatial locality << correct answer >> locality principle stating that if data location is referenced, data locations with nearby addresses will tend to referenced soon Temporal locality << correct answer >> local principle stating data location is referenced then it will tend to be referenced again soon Superscalar << correct answer >> 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 answer >> performance enhancement possible with given improvement is limited by amount the improved feature is used. Weak Scaling << correct answer >> speed up achieved while increasing the size of the problem proportionally to the increase in # of processors Strong Scaling << correct answer >> speed up achieved without increasing size of problem TLB << correct answer >> Translation-Lookaside Buffer: cache that keeps track of recently used address mappings to avoid an access to the page table Parallelization << correct answer >> computing operations in parallel Pipelining << correct answer >> technique where multiple instructions are overlapping in execution, think assemble line Memory << correct answer >> storage area in which programs are kept while running and contains data needed to run programs Control << correct answer >> component of processor that commands datapath, memory, I/O devices according to instructions of program. GPU << correct answer >> Graphics Processing Unit: Hardware that accelerates graphics Cloud Computing << correct answer >> large collections of servers that provide services over the internet ALU << correct answer >> Arithmetic Logic Unit: hardware that performs add, sub, and logical operations like AND, OR RAID 0 << correct answer >> no redundancy, widely used RAID 1 << correct answer >> Mirroring RAID 2 << correct answer >> error detection and correction code, unused RAID 3 << correct answer >> bit interleaving parity, storage concepts
