the equivalent ps command of UNIX in windows

Like we use the ps command in UNIX to find out the PID,the PPID etc of a particular process, and then use that information to kill the process(if necessary), is there a way this could be achieved in Windows. How would i find out the PID and PPID of a particular running application on windows. And how can i find out the exact memory locations occupied by this process. And when i kill the process does the memory occupied by the process gets freed up automatically?

there is an application called tlist that lists all running processes & there PIDs (sorry no mem location's or usage) & an application called kill to kill them (both dos based). I think you get both of these with the resource kit.

Visual Studio comes with Process Viewer & NT has the Task manager (it shows mem usage, but not location).
