• A process is a running program with a PID (process id).
• ps aux lists processes; top shows live use of CPU and memory.
• free -h shows memory; df -h shows disk space; du -sh * shows folder sizes.
• kill PID asks politely (SIGTERM); kill -9 PID forces (SIGKILL) and should be a last resort.
• A full disk or out-of-memory state is a common cause of "the app just died".
