I'll add:

* swap: the amount of disk space set aside to copy physical memory to when 
copying it out of RAM
* rss: Resident Set Size - the part of a process address space which is 
currently resident in RAM
* size: The total address space used by a process
* physical - various definitions, most common one i've seen is the total 
amount of RAM in the system. Also refered to as 'real' in some places

And a link I found that might be of some use:
