What’s the difference between active and inactive memory?
Wired memory is required by the operating system, and can never be paged out of memory. Active memory is memory used by currently-running programs. Inactive memory was used recently by programs which have now been terminated (or haven’t been unused in a long time). Free memory is, as the name suggests, RAM that is not being used.
What happens when your free memory is zero?
