Complex Instruction Set Computer (CISC) - ANSWERSA design that produces a complicated and expensive integrated circuit capable of performing a large variety of complex instructions. Complex instructions can be executed with few machine cycles. Reduced Instruction Set Computer (RISC) - ANSWERSA design that produces a simple, cheap integrated circuit with a basic range of machine instructions. Relies on speed as complex instructions take many machine cycles. Graphics Processing Unit - ANSWERSA specialised electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display. Modern GPUs highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel. Multicore System - ANSWERSDevelopment of CISC architecture with several sets of CPU components in one microprocessor. Parallel Processor System - ANSWERSThe simultaneous use of several processors to perform a single job. A job may be split into a number of tasks each of which may be
