LAB 05 / 08

museum@linux:~$ PROCESS CONTROL ROOM

SEE WHAT IS RUNNING

A program file is not the same thing as a running process. This interactive control room introduces the work a computer is doing right now—entirely as a fictional model.

WHAT YOU WILL LEARN

  • Learn process and PID concepts with ps and a top-like view.
  • Distinguish foreground and background work, then meet signals and the kill concept.
  • Inspect before acting: a high CPU number is a clue, not a complete diagnosis.
PID   COMMAND         CPU
101   museum-shell     1%
205   archive-index    3%
319   runaway-job     99%

Inspect a deterministic fictional process table, use signals deliberately, and reset safely at any time.

SAFETY / BROWSER-ONLY

This interactive lab runs only a fictional browser-memory system. It never runs real shell commands or accesses your files, processes, services, or operating system.
