CISC and RISC Programming

Question 1

What do the CISC and RISC acronyms mean?

Answer 1

• CISC - Complex Instruction Set Computer
• RISC - Reduced Instruction Set Computer

Question 2

What is CISC?

CISC - Complex Instruction Set Computer

Answer 2

• Computer architecture emphasizing a rich
  set of complex instructions.
• Aims to reduce the number of instructions
  needed for complex tasks.
• Often found in traditional desktop and
  server processors.
• Provides versatility in programming.
• May result in slower execution compared
  to RISC architectures due to increased
  complexity.

Question 3

What is RISC?

RISC - Reduced Instruction Set Computer

Answer 3

• Computer architecture design.
• Focuses on a simplified instruction set with
  a small number of basic instructions.
• Aims to optimize performance by
  executing instructions quickly and
  efficiently.
• Commonly found in embedded systems,
  mobile devices, and high-performance
  computing.
• Prioritizes simplicity and efficiency.
• Often results in faster execution speeds
  compared to Complex Instruction Set
  Computer (CISC) architectures.
