Question 22

GPU

Answer 22

Graphics Processing Unit. Has thousands of cores to process parallel tasks effectively. Works sequentially. Used for small, computer intensive tasks and can act together with CPU render graphics but also to perform floating point arithmetic, mastering music projects, encryption, digital signalling processing (DSP) etc.

Question 23

Concurrent processing

Answer 23

AKA Parallel processing. Several cores working together at the same time

Question 24

Co-processor

Answer 24

An extra processor used to supplement the CPU. Performs floating point arithmetic, graphics processing DSP etc (same as GPU)

Question 25

Pipelining

Answer 25

Improving performance by overlapping stages of fetch execute cycle breaking down stages in arithmetic instructions etc. As soon as an instruction exits the pipeline another enters
