Computer Architecture Quiz

What is the main part of the computer that processes data and executes instructions?

• ALU

• CPU

• Cache

• Registers

What does Von Neumann Architecture describe?

• A system where data and instructions are processed in parallel

• A system where data and instructions share the same memory and are processed sequentially

• A system that has separate memory for data and instructions

• A system that does not process data

Which part of the CPU performs mathematical calculations and logical operations?

• Control Unit

• Registers

• ALU

• Program Counter

What does the Control Unit do in the CPU?

• Stores data temporarily

• Directs the flow of data and instructions within the CPU

• Performs logical operations

• Fetches data from memory

Where is temporary data needed for processing stored in the CPU?

• ALU

• Cache

• Registers

• Control Unit

What is the purpose of Cache Memory in the CPU?

• To store data permanently

• To store frequently accessed data close to the CPU

• To hold memory addresses

• To fetch instructions from memory

What is the role of the Program Counter?

• It stores temporary data

• It tracks the address of the next instruction to be fetched

• It performs arithmetic calculations

• It sends control signals

What does the Memory Address Register (MAR) hold?

• The address of the next instruction

• The memory address of data or instructions being accessed

• The data being processed

• Control signals

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

• Temporarily stores control signals

• Temporarily stores data fetched from or written to memory

• Stores the address of the next instruction

• Performs logical operations

What is the purpose of the Bus in a computer system?

• To perform calculations

• To transfer data between the CPU and memory

• To store data temporarily

• To fetch instructions from memory
