On the ubuntu system monitor there are different types of memory listed: Virtual Memory, Resident Memory, Writeable Memory, Shared Memory & X Server Memory. What are the differences between them, and which reflects the actual RAM usage of the process?



Sorry if it's a newbie question :)

  • Virtual memory accounts for all the libraries and executable objects that are mapped into your process, as well as your stack space.


  • Resident memory is the amount of memory that is actually in RAM.


  • Writable memory is the amount of address space that your process has allocated with write privileges.


  • Shared memory is memory that may be simultaneously accessed by multiple programs with an intent to provide communication among them or avoid redundant copies.


  • X server memory is the amount used by the X server for the GUI-session.
