The basics of OS memory management

In this section, we will go into the fundamentals of memory management in modern OSes. Those already familiar with this topic can skim through this section quickly as a refresher.

Memory is among the most fundamental and critical resources available to a running program (process). Memory management deals with the allocation, use, manipulation, ownership transfer, and eventual release of memory used by a process. Without memory management, executing a program is not possible. Memory management is performed by a combination of components, such as the kernel, program instructions, memory allocators, and garbage collectors, but the exact mechanism varies across programming languages and OSes.

In this section, we will look at the memory management lifecycle and then learn the details of how memory is laid out for a process by the operating system.
