Microprocessor Quiz

What is the primary function of a microprocessor?

• To store data

• To process instructions

• To manage power supply

• To provide input to a system

The microprocessor operates using which numeral system?

• Decimal

• Octal

• Binary

• Hexadecimal

The control unit in a microprocessor is responsible for:

• Performing arithmetic operations

• Controlling execution of instructions

• Storing data permanently

• Connecting to external devices

The Arithmetic Logic Unit (ALU) performs which functions?

• Data storage

• Data processing and calculations

• Controlling peripherals

• Managing power supply

The Register Array in a microprocessor is used for:

• Storing temporary data

• Power regulation

• External communication

• Managing I/O devices

The Program Counter (PC) stores:

• The last executed instruction

• The next instruction’s memory address

• The result of arithmetic operations

• The address of input devices

The Instruction Decoder is responsible for:

• Executing instructions

• Converting high-level language to machine code

• Identifying and interpreting machine code instructions

• Storing instruction results

ROM (Read-Only Memory) is primarily used for:

• Storing temporary data

• Storing permanent system instructions

• High-speed cache memory

• Communicating with peripherals

Cache Memory is used to:

• Store frequently used instructions for quick access

• Increase the size of main memory

• Provide backup storage

• Transfer data to external devices

The Memory Address Register (MAR) holds:

• The memory location of the instruction being executed

• The result of an arithmetic operation

• The control signals for the processor

• The output of a computation
