3.3.6 - TestOut ITF Pro: CPU Facts

What is the primary function of the CPU in a computer system?

• To store data permanently

• To perform complex computations

• To provide power to the system

• To display graphics

Which of the following is a measure of a CPU's performance capabilities?

• Byte size

• Clock speed

• Screen resolution

• Battery life

What is the unit of measurement for CPU clock speed?

• Megabytes (MB)

• Gigahertz (GHz)

• Kilowatts (kW)

• Pixels per inch (PPI)

How does increasing the clock speed of a CPU affect its performance and power consumption?

• Increases performance and decreases power consumption

• Decreases performance and increases power consumption

• Increases both performance and power consumption

• Decreases both performance and power consumption

What is Symmetric Multiprocessing (SMP) in computer systems?

• A method to increase storage capacity

• An architecture that allows multiple CPUs to be connected to the same system

• A technique to improve graphics quality

• A way to reduce internet latency

What is one drawback of using Symmetric Multiprocessing (SMP) in computers?

• It reduces the number of available USB ports

• It increases the system's overall cost

• It decreases the system's processing speed

• It limits the amount of RAM that can be used

Which of the following statements is true about CPU brands?

• All CPU brands have the same clock speed

• Different CPU brands may offer different features and performance levels

• CPU brands do not affect the computer's performance

• There is only one brand of CPU available

Why might a computer system use multiple CPUs instead of just increasing the clock speed of a single CPU?

• To reduce the need for a cooling system

• To improve performance without significantly increasing power consumption and heat

• To decrease the size of the computer

• To eliminate the need for a graphics card

What is one potential benefit of having a higher CPU clock speed?

• Longer battery life

• Faster execution of instructions

• Lower system cost

• Increased storage capacity

Which of the following is NOT a factor that affects a CPU's performance?

• Clock speed

• Number of cores

• Screen size

• Cache size
