Stack Buffer

What Does Stack Buffer Mean?

A stack buffer is a type of buffer or temporary location created within a computer’s memory for storing and retrieving data from the stack. It enables the storage of data elements within the stack, which can later be accessed programmatically by the program’s stack function or any other function calling that stack.


Techopedia Explains Stack Buffer

A stack buffer is primarily used by programmers when working with data structure elements within a software program. It can be used for all of the operations performed on a stack, such as for pushing or adding an item and removing or popping the item from the stack.

Whenever a stack is defined within the program’s code and is executed, a temporary buffer or stack buffer is created within the computer memory that holds the data pertaining to the stack. The data is extracted from the stack buffer using the last in, first out (LIFO) method.
