Question

Quizplus · Accepted Answer

Speculative execution is a technique used in computer systems where the processor guesses which instruction will be executed next and executes it before knowing the final outcome of the previous instruction. This allows the processor to continue processing instructions without waiting for the previous instruction to complete, which can improve the overall performance of the system. However, if the processor's guess is incorrect, it will have to discard the work it has done and start over, which can result in a performance penalty.
