[Audio] What is a Stack. STACK 8085 Microprocessors. 

Scene 1

Stack is a set of memory locations reserved in RAM used to store temporary information. It is a shared resource both by microprocessor and programmer. The informations are stored into the  stack,  just like arranging the plates one above the other. Hence the stack operates on the  Last In, First Out  (LIFO) principle.

Scene 2

The location of the most recent data on the stack is known as the  TOP  of the stack.   The 8085 has a 16-bit register known as the  Stack Pointer . The function of the stack pointer is to hold the starting address of the stack.  This address can be decided by the programmer.  he stack pointer always points to the top of the stack. Contents can be stored in the stack using the  PUSH  instruction and can restore the contents by using the  in struction  POP .
