Description
A stack is a linear data structure that follows the Last In, First Out (LIFO) principle, meaning that the most recently added element is the first one to be removed. It operates with two main operations: push, which adds an element to the top of the stack, and pop, which removes the element from the top. Additionally, a peek or top operation allows viewing the element at the top without removing it. Stacks are commonly used in algorithms for parsing expressions, function calls (call stack), undo mechanisms, and managing recursive processes.

ICS 2202: Secondary Storage Management
Secondary storage management in an operating system refers to the processes and techniques used to manage data stored on non-volatile storage devices, such as hard drives, solid-state drives (SSDs), and other storage media. This management is crucial as secondary storage typically holds the majority of an OS's data, including user files, applications, and system data.

ICS 2202: Virtual Memory
Main memory management strategies have a common goal of keeping many processes in
memory simultaneously to allow multiprogramming. However, they tend to require that an entire
process be in memory before it can execute. This requirement that instructions must be loaded in
physical memory to be executed seems both necessary and reasonable, but has the disadvantage
of limiting the size of a program to the size of physical memory.
