dpkg is the low-level package manager for Debian-based systems, while tools like apt and aptitude provide a higher-level interface for package management. dpkg does not handle package dependencies automatically, so users must manually resolve dependencies when installing packages with dpkg. Other package managers like apt handle dependencies automatically.
