Total : the amount of RAM installed on your computer, listed in megabytes
(MB).
Cached : the amount of physical memory used recently for system resources.
Free : the amount of memory that is currently unused or does not contain
useful information (unlike cached files, which do contain useful
information).
A cache is not the same as total memory in use. It is memory allocated to
storage of snippets or addresses for quicker access to a function which may
be used by a program.
These numbers represent "recently", not current.
The graph shows, "now."
Add it up this way...
Free + Cached + In Use + Kernel
(Assumming Kernel is probably around 80.)
Just from the numbers you provided + Kernel, I get 4.00 GB.
(But, that's probably over simplified...)
