CPU Functions and Architecture Quiz

What is the main function of the Control Unit (CU) in the CPU?

• Perform mathematical calculations

• Store user files

• Direct and control other parts of the computer

• Store long-term data

The Arithmetic Logic Unit (ALU) is responsible for:

• Managing the operating system

• Performing calculations and logical operations

• Running computer software

• Storing permanent data

What is the function of registers in the CPU?

• Store large files for a long time

• Temporarily store data very quickly

• Save images and videos

• Calculate internet speed

Why is cache memory important in the CPU?

• It controls computer sounds

• It protects the computer from viruses

• It stores frequently used data to speed up processing

• It sends data to the internet

What does clock speed refer to in a CPU?

• The size of the CPU

• The amount of files it can store

• How fast the CPU performs tasks per second

• The number of users on the computer

What are CPU cores?

• The physical case of the CPU

• Small processors inside the CPU that help it multitask

• Backup memory units

• Cooling fans inside the CPU

Why are multiple cores useful in a CPU?

• They increase the size of the hard drive

• They allow the CPU to store more programs

• They help the CPU perform more tasks at the same time

• They improve internet speed

What is Instruction Set Architecture (ISA)?

• The CPU's power supply system

• The way data is displayed on screen

• A group of basic commands the CPU understands

• The speed at which CPU fans rotate

Why is ISA important?

• It stores all the documents in the system

• It decides what instructions the CPU can understand and execute

• It controls the brightness of the screen

• It increases the number of cores

What does pipelining do in a CPU?

• Increases the number of files that can be saved

• Allows CPU to skip instructions

• Lets the CPU work on different steps of multiple instructions at the same time

• Slows down the processing to save energy
