Processor and Fetch Execute Cycle

What is the purpose of the program counter (PC) register in a processor?

• Perform arithmetic and logic operations
• Store the memory address of a memory location
• Hold the memory address of the next instruction to be executed in the fetch-execute cycle
• Hold the instruction that is currently being executed by the processor

What is the purpose of the control unit in a processor?

• Perform arithmetic and logic operations
• Store data temporarily
• Hold the memory address of the next instruction
• Control the various components of the processor

What are operands in a machine code instruction?

• The type of operation to be carried out
• The memory location of the instruction
• The type of processor being used
• The pieces of data on which the operation is performed

What are the three stages of the instruction cycle?

• Input, Process, Output
• Add, Subtract, Multiply
• Fetch, Decode, Execute
• Load, Store, Jump

What is the purpose of the processor?

• Displays output to the user
• Stores data and instructions for the computer system
• Performs arithmetic and logical operations on data
• Generates a timing signal to synchronize communication between processor components

What are the three stages of the Fetch-Execute cycle?

• Fetch, Store, Execute
• Fetch, Decode, Load
• Fetch, Decode, Execute
• Load, Store, Execute

What are the two primary parts of a machine code instruction?

• Input and output
• Memory and registers
• Interrupts and exceptions
• Opcode and operands

Are instructions for one processor compatible with other processors?

• No, each type of processor has its own instruction set
• Yes, all processors use the same instruction set
• It depends on the type of operation
• It depends on the type of processor

What is the role of the clock in a processor?

• Stores the contents of a memory location
• Generates a timing signal to synchronize communication between processor components
• Holds the instruction currently being executed
• Stores the memory address of a memory location to be read from or written to

What are arithmetic operations?

• Mathematical operations like addition
• Operations that control the fetch-execute cycle
• Operations that store data temporarily
• Operations that hold the memory address of the next instruction
