The Central Processing Unit

What is the primary function of the control unit within the CPU?

• It performs arithmetic and logical operations.

• It decodes instructions

• It stores frequently accessed data for quick retrieval.

• It regulates the clock speed of the CPU.

In the context of CPU architecture, what does the term "Von Neumann architecture" refer to?

• A design where the CPU and GPU are on the same chip.

• A design where the program instructions and data share the same memory and pathways.

• A design that separates the CPU into multiple cores.

• A design that exclusively uses solid-state drives for memory.

What is the first step of the fetch-decode-execute cycle?

• The CPU executes the instruction.

• The CPU decodes the instruction.

• The CPU fetches the instruction from memory.

• The CPU writes the result to memory.

Which component of the CPU is responsible for performing mathematical calculations?

• Control unit

• Arithmetic logic unit (ALU)

• Cache memory

• Clock

What is cache memory used for in a CPU?

• To store the operating system.

• To increase the clock speed.

• To temporarily store data that is frequently accessed or needed by the CPU.

• To permanently store user data.

What does the clock speed of a CPU determine?

• The amount of data it can store.

• The number of instructions it can execute per second.

• The size of the CPU.

• The number of cores in the CPU.

What is the purpose of multiple cores in a CPU?

• To increase the clock speed.

• To store more cache memory.

• To perform multiple tasks simultaneously.

• To reduce the physical size of the CPU.

During which stage of the fetch-decode-execute cycle is the instruction translated into signals that the CPU can act upon?

• Fetch

• Decode

• Execute

• Write-back

What is the role of the Arithmetic Logic Unit (ALU) during the execute phase of the fetch-decode-execute cycle?

• It fetches the next instruction.

• It decodes the instruction.

• It performs the operation specified by the instruction.

• It stores the result in cache memory.

Which of the following is a characteristic of Von Neumann architecture?

• It uses separate buses for data and instructions.

• It has multiple ALUs for parallel processing.

• It has a single memory space for data and instructions.

• It requires manual fetching of instructions.
