Paging Virtual memory breaks programs into fixed-size blocks called pages. If a computer has abundant physical memory, the operating system loads all of a program's pages into RAM.

RSHRD (Shared Memory) Shared memory is the amount of normally reserved memory that a program can free up by swapping out pages to virtual memory (hard disk space).

Understanding Linux memory management—page tables, swapping, and memory allocation—enables system administrators and developers to optimize performance and troubleshoot issues effectively. With tools ...
