What are major differences betwen CISC Vs RISC?

CISC: CISC stands for Complex Instruction Set Computer. In CISC the instruction set has various, different instructions that can be used for complex operations and the performance can be optimized with emphasis on hardware. It also eliminates the need for generating machine instructions for the processor.

RISC: RISC stands for Reduced Instruction Set Computers. In RISC The instruction set is reduced, and most of these instructions are very primitive and the performance is optimized which emphasized software. It uses a few simple addressing modes that use register-based instruction.
