Detailed explanation-1: -CISC ISAs use more transistors in the hardware to implement more instructions and more complex instructions as well. RISC needs more RAM, whereas CISC has an emphasis on smaller code size and uses less RAM overall than RISC.
Detailed explanation-2: -CISC (complex instruction set computer) processors are used in desktop and laptop computers. This type of processor can process more complex instructions. For example, a single instruction can involve loading two values, calculating their sum, and storing the result back in memory.
Detailed explanation-3: -The most commonly used is CISC, because in terms of price, CISC is much cheaper than RISC. However, in terms of performance, RISC is much better than CISC. This is why RISC is more expensive. CISC processors of this type are usually manufactured by Intel and AMD.
