ISA, RISC, CISC

What is Instruction Set Architecture (ISA) and how does it relate to RISC and CISC?

• ISA is a type of computer virus that affects RISC and CISC systems

• ISA stands for International Software Association and has no relation to RISC and CISC

• ISA defines the instructions that a CPU can execute and it relates to RISC and CISC through their different design philosophies.

• ISA is a type of programming language and has no connection to RISC and CISC

Explain the concept of Reduced Instruction Set Computing (RISC) and provide an example of a RISC architecture.

• ARM architecture is an example of RISC architecture.

• PowerPC architecture is an example of RISC architecture.

• Intel architecture is an example of RISC architecture.

• AMD architecture is an example of RISC architecture.

What are the key differences between RISC and CISC architectures?

• RISC architectures and CISC architectures have the same set of instructions, but in a different order.

• RISC architectures have a larger set of simple instructions, while CISC architectures have a smaller set of complex instructions.

• RISC architectures have a smaller set of simple instructions, while CISC architectures have a larger set of complex instructions.

• RISC architectures have a larger set of complex instructions, while CISC architectures have a smaller set of simple instructions.

Discuss the advantages of RISC architecture over CISC architecture.

• CISC architecture has better performance in pipelining

• RISC architecture has a simpler instruction set, faster execution, and better performance in pipelining.

• RISC architecture has a more complex instruction set

• RISC architecture has slower execution

What are the disadvantages of Complex Instruction Set Computing (CISC) architecture?

• Complexity, higher power consumption, and slower execution speed

• Simplicity, lower power consumption, and faster execution speed

• Simplicity, lower power consumption, and limited functionality

• Limited functionality, lower power consumption, and faster execution speed
