What is the difference between CISC and RISC?

RISC has a reduced instruction set where each instruction can be executed in a single clock cycle. This means that programs often are longer to the developer but are more easily executable on lower powered devices such as mobile phones.CISC on the other hand has instructions that can take multiple clock cycles, and is typical of desktop processors. The programs are more simple for the developer.
