Instruction Cycle Quiz

What are the main steps in an instruction cycle?

• Fetch, Decode, Execute, Store

• Input, Process, Output, Store

• Start, Process, End

• Initialize, Execute, Terminate

Which of the following are factors that affect execution speed?

• Processor speed and memory size

• Color of the computer case

• Brand of the keyboard

• Type of monitor used

Speculative execution increases execution speed by:

• Executing instructions before they are needed

• Waiting for all instructions to be confirmed

• Reducing the number of instructions executed

• Increasing the clock speed of the processor

Choosing the right instruction set is important for processor performance because:

• It determines the efficiency of executing instructions.

• It has no impact on the processor's speed.

• It only affects the processor's power consumption.

• It is irrelevant to modern processors.

What is the purpose of pipelining in a CPU?

• To increase the clock speed of the CPU

• To allow multiple instructions to be processed simultaneously

• To reduce the power consumption of the CPU

• To enhance the graphics processing capabilities

How does a cache improve processor performance?

• By increasing the clock speed of the processor

• By reducing the time needed to access data from the main memory

• By increasing the number of cores in the processor

• By improving the graphics processing capabilities

What is the role of registers in a CPU?

• To store data temporarily for quick access

• To connect the CPU to external devices

• To manage power supply to the CPU

• To control the clock speed of the CPU

What are the primary differences between embedded/mobile CPUs and microcomputer CPUs?

• Embedded/mobile CPUs are designed for low power consumption and efficiency, while microcomputer CPUs focus on performance.

• Microcomputer CPUs are used in smartphones and tablets, whereas embedded/mobile CPUs are used in desktops and laptops.

• Embedded/mobile CPUs have higher clock speeds compared to microcomputer CPUs.

• Microcomputer CPUs are generally more expensive than embedded/mobile CPUs.
