Maximum number of kilobytes of memory that can be allocated to a process. For operating systems with no virtual memory, this value is typically equal to the total amount of physical memory minus memory used by the BIOS and OS. For some operating systems, this value may be infinity - in which case, 0 should be entered. In other cases, this value could be a constant - for example, 2G or 4G.
