1.We have learned from this lab Data are stored into the stack with a PUSH instruction and removed with a POP instruction.Each location address has difference of 2.Fixed location of data is stack pointer.Stack pint can store 16 bit.PUSH will move the data to the top and the opset will continue to decrease by 2.POP will move the data to the bottom and the opset will continue to increase by 2.
2. stack segment is a register that holds address of stack memory,where as data holds address of data memory temporally .
