Retrieval Practice 1.1.1

What is the primary function of the ALU in a computer system?

• To store data temporarily

• To perform arithmetic and logical operations

• To manage input and output devices

• To control data flow between registers

During the Fetch-Execute cycle, what is the first step?

• Execute the instruction

• Decode the instruction

• Fetch the instruction from memory

• Store the result

Which of the following is NOT a part of the Fetch-Execute cycle?

• Fetch

• Decode

• Execute

• Encrypt

What is the function of buses in the CPU?

• To perform logical operations

• To connect different components and transfer data

• To store instructions

• To execute programs

Which component is essential for executing instructions in the CPU?

• Control Unit

• Buses

• Arithmetic-Logic Unit (ALU)

• Dedicated registers

What is the term for the control unit's action of accepting the next instruction during each clock cycle?

• Instruction Fetch

• Data Retrieval

• Memory Allocation

• Process Termination

Which component is connected to the system bus to handle input and output operations?

• Processor

• Memory

• Input and Output

• Control Unit

What does the "Bus request" signal indicate?

• Data is being read from RAM

• A device is requesting use of the data bus

• The CPU has granted access to the data bus

• Operations are being synchronized

Why do buses consist of multiple lines?

• To increase the speed of data transfer

• To reduce the cost of the system

• To make the system more complex

• To decrease the power consumption

What is the sole purpose of an address bus?

• To identify the address of the location in cache or main memory

• To process data in the CPU

• To store data permanently

• To increase the speed of the processor
