more information needed maybe a screenshot. The tag says 'OS X' which version? What laptop? What application is saying this? –  Journeyman Geek Oct 24 '12 at 5:17
    
It is probably the current load on the CPU and RAM. –  Henning Klevjer Oct 24 '12 at 5:48

Most likely, it refers to the percentage of your RAM that's used to hold application data and running programs. Most of the rest is typically either page cache, kernel data, or free.
