A Level Computer Science (H446) - 1.2.1a) CISC and RISC

What is the purpose of the instruction set in a computer?

• To connect to the internet

• To execute machine code instructions

• To store data in memory

• To display graphics on the screen

What are the two main categories of instruction sets for processors?

• Memory and Storage

• Cisc and Risc

• Complex and Simple

• Binary and Decimal

Which type of processor architecture tends to have more complicated hardware and circuitry?

• RISC

• Neither have complicated hardware

• CISC

• Both have the same level of complexity

Which architecture requires fewer transistors and less complex hardware?

• Both require the same amount of transistors and hardware

• RISC

• CISC

• Neither require any transistors or hardware

Where is the CISC architecture mainly found?

• Smart TVs

• Printers

• Desktop computers and laptops

• Smartphones

What is the aim of RISC processors?

• To use complex instructions

• To execute instructions within a single clock cycle

• To have a large number of instructions in the assembly program

• To require more transistors and complex hardware

What did it take well over a decade for RISC architecture to gain?

• Influence and resources

• Sophistication of compiler technology

• Software support

• Acceptance on a large commercial scale

What did Intel x86 processors become increasingly difficult to develop?

• Because they were becoming less popular

• Because they were becoming increasingly unwieldy

• Because they were becoming more expensive

• Because they were becoming less powerful

Which type of processors far outstrip Intel CISC processors in sales?

• CISC processors

• ARM processors

• Intel x86 processors

• RISC-based processors

Why are RISC processors more commonly found in mobile devices?

• They are cheaper to produce

• They consume less power

• They have a larger instruction set

• They are more powerful
