Differences Between Cisc and Risc Processors

William, Rohan, and Kiara are building a computer. What is the purpose of the instruction set they are installing?

• To execute machine code instructions

• To store data in main memory

• To perform calculations in the execution unit

• To load values into registers

Benjamin and Isabelle are studying computer architecture and they came across two main categories of instruction sets. Can you help Arthur identify what these two categories are?

• Complex Instruction Set Computer (Sisk) and Reduced Instruction Set Computer (Risk)

• High-level Language and Low-level Language

• Main Memory and Execution Unit

• Registers and Clock Cycles

Which architecture tends to have more complicated processor hardware?

• Complex Instruction Set Computer (Cisc)

• Reduced Instruction Set Computer (Risc)

• Both architectures have equally complicated hardware

• Neither architecture has complicated hardware

What is an example of a complex instruction in the Complex Instruction Set Computer (Cisc) architecture?

• Malt

• Num1 times Num2

• Product equals Num1 times Num2

• Load and store values in memory

Daniel, Matilda, and William are working on a project to build a computer. They are discussing which architecture would require fewer clock cycles to complete each instruction. What do you think they should choose?

• Reduced Instruction Set Computer (Risc)

• Complex Instruction Set Computer (Cisc)

• Both architectures require the same number of clock cycles

• Neither architecture requires clock cycles

Kiara is planning to buy a new device and she is curious about the architecture of the device. She learned that the Complex Instruction Set Computer (Cisc) architecture is mainly found in which of the following devices today?

• Desktop computers and laptops

• Smart TVs and home assistants

• Smartphones and tablets

• Printers and thermostats

Oscar, Alexander, and James are working on a project to design a computer architecture. They are considering the Reduced Instruction Set Computer (Risc) architecture. What is one advantage they could gain from using the Risc architecture?

• It would require less energy to run

• It would require more complex hardware

• It would allow for variable length instructions

• It would require a higher number of instructions per program

Evie, Aarav, and Ava are working on a project to design a portable device with low power consumption. Which architecture should they consider to be more popular for such devices?

• Reduced Instruction Set Computer (Risc)

• Complex Instruction Set Computer (Cisc)

• Both architectures are equally popular

• Neither architecture is popular in low power devices

Ava, Sophie, and Anaya are studying computer architecture. They are discussing the Reduced Instruction Set Computer (Risc) architecture. Sophie argues that there was a major disadvantage of Risc architecture in the early days. What could be the disadvantage she is referring to?

• Lack of software support

• High energy requirements

• Limited number of instructions

• Difficult to develop

Arthur, Elsie, and Neha are running a computer store. They noticed that one type of computer architecture has seen a significant increase in sales compared to the other. Which architecture could it be?

• Reduced Instruction Set Computer (Risc)

• Complex Instruction Set Computer (Cisc)

• Both architectures have similar sales

• Neither architecture has seen significant sales
