(1)Ans:-
I learnet from this module Stack sagment,LIFO (Last in, First out),PUSH,POP,Stack Pointer (SP),Stack Segment (SS), For Resester AX, BX, CX and DX.
(2) Ans:
Stack segment:-The Stack Segment is a segment that holds astack. It's a stack implementation of memory locations. As the stack is a segment, it is a contiguous array of memory locations.
We use the stack segment because in the stack segment we can store the four registers we have in Ax, Bx, Cx, Dx.The stack segment register (SS) is usually used to store information about the memory segment that stores the call stack of currently executed program.
