A hardware stack refers to the physical components of a computer system, typically arranged in layers. It includes the processor, memory (RAM), storage (hard drive or SSD), and input/output devices (keyboard, mouse, monitor, etc.).
- hardware stack - a stack implemented in and entirely managed by hardware, this stack will have dedicated memory and registers in the physical hardware of the system.
- software stack - a stack implemented with and entirely managed by software, this stack will use a small piece of main RAM and variables declared in the program software (making it much easier to modify if necessary than a hardware stack).

Explain the difference between Hardware and Software?
A stack is a concept in computer science that works like this: You push value A into the stack, and it takes position 1. Then you pop the stack, and get A. If you were to push A, then B, A would be pushed into position 2, and B would be in position 1. When you pop, however, you can only get the value in position 1 (B) and A would pop to position 1. This is useful for data storage, but, expanding, you can do simplified arithmetic if you store data in positions 1 and 2, and define that the ADD command sums positions 1 and 2, erases 2, and stores the sum in 1. And so on. A software stack is a stack that is implemented in the software of a computer: A large series of commands is given to the processor that make it store data in a "stack" somewhere in memory, and are usually sequential. Pros: Simple to implement. Cons: Slow and resource consuming. A hardware stack is a series of memory units, often built into the processor, that quite literally are a stack. The only way to store data in them is to push, and the only way to access it is to pop from the first position (top of the stack). Pros: Very fast, and is useful to the processor, even when you aren't actively using it. Cons: Has to be engineered, and is often expensive to make.
Will technology one day progress to the point where there will not be a need to distinguish between hardware and software meaning that no difference would be perceived between the 2 types of interface?
No, hardware is of necessity a physical mechanism and software is procedural information. The same software can run on very different hardware, as long as it interprets it the same way producing the same physical effect will have the same result. But hardware without software will do nothing (unless the hardware is fixed single purpose hardware that needs no software).
What function for stack pointer of the register?
A stack pointer is a register pointing to the top of a stack. It supports the fundamental stack manipulations (push and pop) in an efficient manner. Most micro processor hardware has build-in hardware support for stack pointers, typically both in form of dedicated stack pointer registers and in form of addressing modes which support the creation and maintenance of stacks through general-purpose pointer registers. In software, many programming languages feature constructs suited for implementation of stack pointers within the high-level language (such as post-increment and pre-decrement operators in C).
Which one is better software control or hardware control?

What is the special hardware and software needed in Engineering and Manufacturing?
sir , i am computer hardware engineer, and find job
Is VDU hardware or software?
A VDU is hardware.
Is scanner a hardware or software?
A scanner is both hardware and software, the device itself is hardware (all devices are hardware) but the driver(a program) that runs it is software.
Is RAM software or hardware?
hardware
Is a microphone a hardware or software?
A microphone is hardware. Software is what programs and games are called.
Is a computer a software of hardware?
both a hardware and software
Is the motherboard hardware or software?
Motherboards are hardware components, not software.
What was first software or hardware?
Have to be hardware. How could you write software if there were no hardware to write it on?
Why is hardware needed in a computer?
Software. Short and sweet. Hardware needs software to work.
Is webcam a hardware or software?
hardware
Is hardware tangible and software intangible?
Yes. Hardware can be touched and software cannot.
Is a scanner hardware of software?
A scanner is a hardware device that is operated by software.
What is the principle of Equivalence of Hardware and Software?
anything that can be done with hardware can also be done with software and anything done with software can also be done with hardware.
