MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -A complex instruction set computer (CISC /ˈsɪsk/) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.

Detailed explanation-2: -CISC and RISC (Complex and Reduced Instruction Set Computer, respectively) are dominant processor architecture paradigms. Computers of the two types are differentiated by the nature of the data processing instruction sets interpreted by their central processing units (CPUs).

Detailed explanation-3: -Explanation: In order to implement complex instructions, CISC architectures use microprogramming. Explanation: The advantages of RISC processors are that they can work at high clock frequency, can be designed, developed and tested more quickly with a high speed.
