Computer Architecture

What is the main role of the CPU in a computer?

• To store permanent data

• To process instructions and control the computer

• To connect devices together

• To manage electricity flow

What is a microprocessor?

• A very small memory chip

• A tiny CPU on a single integrated circuit

• A type of hard drive

• A graphics card

Which of the following is a difference between a CPU and a microprocessor?

• CPU is hardware, microprocessor is software

• CPU is external, microprocessor is internal

• Microprocessor is a CPU on a single chip

• CPU can only store data

Why is the CPU often called the "brain" of the computer?

• It controls all data and executes instructions

• It stores all files permanently

• It handles only input devices

• It powers the computer

Which device commonly contains a microprocessor?

• Oven

• Light bulb

• Mouse

• Paper printer

What is Von Neumann architecture?

• A model where CPU and GPU share memory

• A model where data and instructions share the same memory

• A model with multiple CPUs in one

• A model that uses only cache memory

Why do instructions and data share the same memory in Von Neumann architecture?

• To make the CPU cheaper and simpler

• To improve storage capacity

• To double clock speed

• To avoid using cache

What is the role of the Control Unit (CU)?

• Stores the program instructions

• Carries out logical operations

• Directs the flow of data and instructions

• Provides electricity to components

What is the role of the Arithmetic Logic Unit (ALU)?

• To fetch data

• To carry out calculations and logic

• To control memory

• To store variables

What is the role of registers in a CPU?

• Long-term storage

• Holding small amounts of high-speed data temporarily

• Backing up data

• Controlling cache
