The CISC stands for ____
A
Computer Instruction Set Compliment
B
Complete Instruction Set Compliment
C
Computer Indexed Set Components
D
Complex Instruction set computer
Explanation: 

Detailed explanation-1: -A computer in which individual instructions may perform many operations and take many cycles to execute, in contrast with reduced instruction set computer (RISC).

Detailed explanation-2: -Explanation: CISC Processor : It is known as Complex Instruction Set Computer.

Detailed explanation-3: -CISC (Complex Instruction Set Computer) and RISC (Reduced Instruction Set Computer) are two forms of CPU design. CISC uses a large set of complex machine language instructions, while RISC uses a reduced set of simpler instructions.

Detailed explanation-4: -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-5: -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.
