32. Introduction to Stack Operations
This chapter discusses stack operations and different addressing modes used in computing. It explains the basic stack operations such as push, pop, and basic arithmetic operations performed on stack data. Additionally, various addressing modes, including immediate, direct, indirect, and displacement addressing, are elaborated along with their advantages and disadvantages for program execution.

What we have learnt
- Stack operations consist of pushing and popping elements, with basic arithmetic operations available.
- Different addressing modes enhance instruction flexibility in programming, each with distinct use cases.
- Displacement modes allow for effective address generation, optimizing memory access in programming.
Key Concepts
- -- Stack Operations
- Fundamental operations that include adding and removing elements from a stack data structure, primarily push (to add) and pop (to remove).
- -- Addressing Modes
- Techniques used to specify the operands for instructions in a program, including immediate, direct, indirect, and displacement addressing.
- -- Displacement Addressing
- An addressing mode that computes the effective address of an operand based on a base address plus an offset.
