Commentary

Operating system view of a Process

  • A program is segmented into several regions of memory.
  • TODO: Insert picture of process here with Stack/Heap/Data/Text sections.

Stack Memory

  • Automatically allocated data structure
  • Typically used for short-lived data.
  • Any time we create a variable, it is placed on the stack.
  • Allocating

Heap Memory

  • Heap/Free Store Data Structure
  • Used for longer lived and larger memory allocations.
  • More expensive to allocate, as we have to request memory from operating system (requires a context switch to the system)
    • Memory has to be searched for (either from the 'heap/free store' data structure, or otherwise allocated in the process)
