Superscalar {Ans: An advanced pipelining technique that enables the processor to execute more than one instruction per clock cycle by selecting them during execution}Uniform memory access (UMA) {Ans: A multiprocessor in which latency to any word in main memorys is about the same no matter which processor requests the access}Sticky bit {Ans: A bit used in rounding in addition to guard and round that is set whenever there are nonzero bits to the right of the round bit}Personal Computer(PC) {Ans: A computer designed for use by an individual, usually incorporating a graphics display, a keyboard, and a mouse}Context switch {Ans: A changing of the internal state of the processor to allow a different process to use the processor that includes saving the state needed to return to the currently executing process}Weak scaling {Ans: Speed-up achieved on a multiprocessor while increasing the size of the problem proportionally to the increase in the number of processors}
