Address Register for Storing 8-bit Addresses

The address register is used for storing the 8-bit addresses in a computer system. It is an important component of the CPU (Central Processing Unit) and is used to reference memory locations. The correct answer for the register used for storing 8-bit addresses is option 'D', which means all of the mentioned registers can be used for this purpose.

R0 of Selected Bank of Register

R0 is a general-purpose register used for storing data and addresses. It can be used in a bank of registers, which means that there can be multiple copies of R0 in the system, each with a different value. However, R0 is not specifically designed for storing addresses, and other registers may be better suited for this purpose.

R1 of Selected Bank of Register

Similar to R0, R1 is a general-purpose register that can be used for storing data and addresses. It can also be used in a bank of registers, but like R0, it is not specifically designed for storing addresses.

Stack Pointer

The stack pointer is a register that keeps track of the top of the stack. It is used for storing temporary data and addresses, and it is commonly used for subroutine calls and interrupts. While it can be used for storing addresses, it is not specifically designed for this purpose.

All of the Mentioned

Option 'D', which states that all of the mentioned registers can be used for storing 8-bit addresses, is correct. While R0, R1, and the stack pointer are not specifically designed for storing addresses, they can all be used for this purpose. The choice of which register to use will depend on the specific requirements of the program and the availability of registers at any given time.
