Understanding CPU Architecture

What does CPU stand for?

• Computer Processing Unit

• Central Processing Unit

• Central Processing Core

• Centralized Processing Unit

What are the main components of a CPU?

• Memory Management Unit (MMU)

• Arithmetic Logic Unit (ALU), Control Unit (CU), Registers

• Input/Output Controller (IOC)

• Graphics Processing Unit (GPU)

Explain the function of the ALU in a CPU.

• The ALU in a CPU performs arithmetic and logical operations.

• The ALU controls the CPU's clock speed.

• The ALU is responsible for input/output operations.

• The ALU manages memory storage in the CPU.

What is the purpose of the control unit in a CPU?

• To store data temporarily during processing.

• To increase the CPU's clock speed.

• To direct the operation of the CPU and manage instruction execution.

• To provide power to the CPU components.

Define clock speed and its significance in CPU performance.

• Clock speed is the amount of physical space a CPU occupies.

• Clock speed refers to the number of cores in a CPU.

• Clock speed is the frequency at which a CPU operates, and it significantly impacts CPU performance by determining how many instructions can be processed per second.

• Clock speed is the temperature at which a CPU operates.

What is pipelining in CPU architecture?

• Pipelining is a method to increase the clock speed of a CPU.

• Pipelining refers to the process of cooling a CPU to enhance performance.

• Pipelining is a technique that allows a CPU to execute only one instruction at a time.

• Pipelining is a technique that allows multiple instruction phases to be processed simultaneously in a CPU.

Describe the difference between RISC and CISC architectures.

• RISC uses a small set of simple instructions for efficiency, while CISC uses a larger set of complex instructions for more functionality.

• CISC is designed for high-speed processing, while RISC is focused on low power consumption.

• RISC architectures are primarily used in desktop computers, while CISC is used in mobile devices.

• RISC uses a larger set of complex instructions, while CISC uses a small set of simple instructions.

What role does cache memory play in CPU performance?

• Cache memory has no impact on CPU performance and is unnecessary.

• Cache memory slows down CPU performance by increasing data retrieval time.

• Cache memory significantly enhances CPU performance by providing faster access to frequently used data and instructions.

• Cache memory is used to store all data permanently for the CPU.

What is a multi-core processor?

• A multi-core processor is a graphics card designed for rendering images.

• A multi-core processor is a CPU with multiple processing units (cores) that can execute instructions concurrently.

• A multi-core processor is a single processing unit that can only execute one instruction at a time.

• A multi-core processor is a type of memory storage device.

Explain the concept of hyper-threading.

• Hyper-threading allows multiple CPUs to work on a single thread.

• Hyper-threading is a technology that allows a single physical CPU core to execute two threads simultaneously, improving performance and resource utilization.

• Hyper-threading is a technology that enables a CPU to run multiple operating systems simultaneously.

• Hyper-threading is a method to increase the clock speed of a CPU.
