MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Explanation: CISC stands for complex instruction set computer. It is mostly used in personal computers. It has a large instruction set and a variable length of instructions.

Detailed explanation-2: -Complex instruction set computer (CISC) In comparison to a RISC processor, the CISC processor: is expensive to design and produce.

Detailed explanation-3: -It has basically three types, they are as follows: CISC (Complex Instruction Set Computer) RISC (Reduced Instruction Set Computer) EPIC (Explicitly Parallel Instruction Computing)

Detailed explanation-4: -CISC is most often used in automation devices whereas RISC is used in video and image processing applications. When microprocessors and microcontroller were first being introduced, they were mostly CISC. This was largely because of the lack of software support present for RISC development.

Detailed explanation-5: -The CISC approach attempts to minimize the number of instructions per program, sacrificing the number of cycles per instruction. RISC does the opposite, reducing the cycles per instruction at the cost of the number of instructions per program.
