Memory usage

The Active monitor from apple is a bit confusing, especially on the memory statistic.

So what are all these terms means?

Wired memory
This information can’t be cached to disk, so it must stay in RAM. The amount depends on what applications you are using.

Active memory
This information is currently in RAM and actively being used.

Inactive memory
This information is no longer being used and has been cached to disk, but it will remain in RAM until another application needs the space. Leaving this information in RAM is to your advantage if you (or a client of your computer) come back to it later.

Free memory
This memory is not being used.
