Which of the following is NOT a primary function of the CPU?

• Executing instructions

• Performing calculations

• Storing data permanently

• Controlling other components

The part of the CPU that performs arithmetic and logical operations is called the:

• Control Unit

• Arithmetic Logic Unit (ALU)

• Cache Memory

• Registers

The Control Unit's main job is to:

• Perform calculations

• Store data

• Fetch, decode, and execute instructions

• Manage the flow of electricity

Small, high-speed storage locations within the CPU are called:

• Cache

• Registers

• RAM

• Hard drives

Which of these best describes the fetch-decode-execute cycle?

• The process of the CPU shutting down and restarting

• The fundamental process by which the CPU processes instructions

• The way data is transferred between the CPU and RAM

• The process of installing new software

What does the CPU use to keep track of the next instruction to be executed?

• Memory Address Register (MAR)

• Memory Data Register (MDR)

• Program Counter (PC)

• Instruction Register (IR)

Cache memory is used to:

• Store data permanently

• Speed up access to frequently used data

• Perform complex calculations

• Control other components

What is the role of the clock in a CPU?

• To regulate the temperature of the CPU

• To synchronize the CPU's processes

• To provide power to the CPU

• To store data temporarily

Clock speed, measured in Hertz (Hz), refers to:

• The amount of data the CPU can store

• The number of instructions the CPU can execute per second

• The size of the CPU

• The amount of power the CPU consumes

What is the purpose of the Memory Data Register (MDR)?

• To store the address of the memory location being accessed.

• The number of instructions the CPU can execute per second

• The size of the CPU

• To keep track of the next instruction to be fetched.
