Data are stored in and retrieved from a queue on a first-in-first-out (FIFO) basis Thus, if we assume that the queue grows in the direction of increasing addresses in the memory, which is a common practice, new data are added at the back (high-address end) and retrieved from the front (low-address end) of the queue

How is data stored and organized on the stack?
The stack stores data from the top down, following a last in, first out (LIFO) data structure. This means that the program adds data to the top of the stack and removes data from the top of the stack. In this way, the top of the stack always contains the most recently stored data that has not yet been removed.What is stack and how it is stored in computer memory?
Stack memory is a memory usage mechanism that allows the system memory to be used as temporary data storage that behaves as a first-in-last-out buffer. One of the essential elements of stack memory operation is a register called the Stack Pointer.What is stack organization and its types?
What is stack organization and its types? It is the CPU's most crucial feature. It saves information so that the last element saved is retrieved first. A memory space with an address register is called a stack. There are two types of stacks organization: register stack and memory stack.- Stack memory allocation takes place on contiguous blocks of memory. As this allocation occurs in the function called stack, it is commonly referred to it as a stack memory allocation. The compiler calculates how much memory to allocate for each type of variable specified in the program.
