H466 - CISC vs RISC

Which of the following is a characteristic of RISC?

• Less complex and faster to execute instructions

• More complex and lengthy instructions

• Instructions of varying lengths

• Requires fewer lines of code

What is a common feature of RISC instructions?

• All instructions are of the same length

• Instructions vary in length

• Instructions are more complex

• Instructions require fewer lines of code

What is the effect of CISC instructions on the number of lines required?

• Decrease the lines required

• Increase the lines required

• Have no effect on the lines required

• Double the lines required

How does CISC architecture achieve its goal?

• By using commands that take less than one clock cycle

• By using commands that take more than one clock cycle

• By using only simple commands

• By avoiding the use of MULT commands

What is a potential advantage of using a MULT command in CISC architecture?

• It simplifies the processor design

• It allows multiplication of numbers not possible on other processors

• It reduces the power consumption

• It increases the number of instructions

Which disadvantage affects the execution speed?

• Efficient use of RAM.

• Takes more than one clock cycle to execute.

• Less work for the compiler.

• Multiple addressing modes available.

What began to form beneath the surface of CISC's control and order?

• Cracks

• Innovations

• Solutions

• Expansions

Who were the pioneers of the RISC movement?

• Steve Jobs and Bill Gates

• John Cocke and the UC Berkeley RISC project

• Alan Turing and Charles Babbage

• Tim Berners-Lee and Vint Cerf

What is the role of hybrid processors according to the text?

• They are purely CISC

• They blend the best of both CISC and RISC philosophies

• They are purely RISC

• They are obsolete

What does the text imply about the relationship between Intel and AMD?

• They are competitors with no common goals

• They both push CISC to new heights

• They focus solely on RISC

• They have no influence on modern computing
