CPU and Memory Quiz

What does the control unit in a CPU do?

• Performs arithmetic operations

• Coordinates activities of the computer

• Stores data long-term

• Manages input/output devices

The primary function of the ALU is to:

• Control data flow

• Store instructions

• Perform arithmetic and logical operations

• Manage memory addresses

Which component connects the CPU to main memory?

• Data bus

• Address bus

• Control bus

• System bus

Which of the following is NOT a type of memory?

• Cache

• RAM

• Hard disk

• Register

The fetch-decode-execute cycle is performed by:

• Memory

• ALU

• CPU

• I/O devices

What is the main purpose of cache memory?

• To store long-term data

• To increase the speed of data access for the CPU

• To manage virtual memory

• To hold operating system files

The process of converting data into a form that can be stored or transmitted is called:

• Encoding

• Decoding

• Signal processing

• Data compression

Which addressing mode involves executing an instruction with the operand specified directly in the instruction?

• Immediate

• Register
