AHJ: U3 Computer Architecture

Which of the following is NOT a component of the von Neumann architecture model?

• ALU

• Control Unit

• System Clock

• HDMI port

What does ALU stand for in computer science?

• Arithmetic Logic Unit

• Accumulator Load Unit

• Address Line Unit

• Algorithm Lookup Unit

Which component of the computer is responsible for executing instructions and performing calculations?

• CPU

• BIOS

• Status register

• USB port

What is the purpose of the Control Unit in a computer system?

• It controls the flow of data within the CPU.

• It stores the instructions and data being processed.

• It performs arithmetic and logical operations.

• It connects the computer to external devices.

Which component of a computer system generates a regular electronic pulse to synchronize operations?

• System Clock

• Flag

• VGA

• Address bus

Immediate Access Store (IAS) is another term for:

• CPU

• BIOS

• Memory

• Accumulator

The Accumulator is a register that:

• Stores the memory address of the next instruction to be executed.

• Holds the current instruction being executed.

• Stores the result of arithmetic and logical operations.

• Stores the status of the CPU.

Registers in a computer system are used to:

• Store instructions and data.

• Execute arithmetic and logical operations.

• Connect peripherals to the computer.

• Store memory addresses for data access.

The Status Register in a CPU stores:

• The current instruction being executed.

• The result of arithmetic and logical operations.

• The memory address of the next instruction.

• The status flags indicating the outcome of operations.

What is the purpose of a flag in computer science?

• It represents a physical component of a computer.

• It indicates the presence of a peripheral device.

• It is used to signal an interrupt request.

• It stores a single bit of information indicating a condition.
