IT Concept: Systemd Unit Types
The different unit types in systemd: service, socket, timer, mount, target, and more — each with a specific purpose.
Systemd Unit Types — .service (daemons), .timer (cron replacement), .socket (socket activation), .mount (filesystems), .target (grouping/sync points like multi-user.target), .path (watch filesystem paths), .slice (cgroup resource limits). List all: systemctl list-unit-files --type=timer.
