-The Stack pointer is a sixteen bit register used to point at the stack.

- In read write memory the locations at which temporary data and return addresses are stored is known as the stack.

- In simple words stack acts like an auto decrement facility in the system.

- The initialization of the stack top is done with the help of an instruction LXI SP.
