To specify the address in memory for the next read or write
What is the role of the Instruction Interpreter Module?
To interpret each instruction and generate control signals
What is the main concept of the von Neumann architecture?
Data and instructions are stored in a single read-write memory
What is the role of the I/O Buffer Register (I/OBR)?
Used for the exchange of data between an I/O module and the CPU
What is the basic function of a computer?
To execute instructions stored in memory
What is the purpose of the Main Memory?
To store instructions and data temporarily
How is the address of the next instruction determined?
By adding a fixed number to the address of the previous instruction
What is the purpose of the operand address calculation (oac) stage?
To determine the address of the operand
What is the primary purpose of interrupts in computer architecture?
To allow other modules to interrupt the normal processing of the processor
What is the role of the instruction fetch (if) stage?

What is the primary purpose of the instruction operation decoding (iod) stage?
To analyze the instruction to determine the type of operation to be performed
What happens when an interrupt occurs during the processing of another interrupt?
The new interrupt request signal is stored and checked later.
What is the purpose of an I/O module in a computer system?
To exchange data directly with the processor.
What is the primary function of a bus in a computer system?
To provide a pathway for moving data among system modules.
What determines the maximum possible memory capacity of a system?
The width of the address bus.

To designate the source or destination of data.
What is the primary function of the data bus in a computer system?
To provide a pathway for moving data among system modules.
What happens when two devices transmit simultaneously on a bus?
The signals overlap and become garbled.
