I can see from this page here: http://www.linuxatemyram.com/

That the correct amount of free ram is on the "-/+ buffers/cache" line. The extra ram being used is for disk caching. However, I noticed that the total amount of memory used listed in "-/+ buffers/cache" line is significantly less than the sum total of the "RES" column of the processes shown in top. And AFAIK, the "RES" column is how much physical memory is being used by a process.

How do you explain this discrepancy?
