are mainly used in desktops and laptops. - 7Where is RISC mainly used?RISC (reduced instruction set computing)
is mainly used in tablets and phones, due to the simpler architecture. - 8What is overclocking?Overclocking is forcing the CPU to process more instructions quickly than the manufacturer initially intended for it to be.
