A thread is also called a lightweight process.
•
Physical Memory Used — The amount of physical memory in kilobytes being used by
the specified process.
•
Virtual Memory Used — The amount of virtual memory in kilobytes being used by the
specified process, or the size of the process in real memory plus swap.
Specify the process by its command name or process ID. (PID). Entering a PID overrides
