How does dpkg work?
dpkg works by using a database to keep track of installed packages and their dependencies. When a package is installed, dpkg extracts the files from the package archive and places them in the appropriate directories on the system. dpkg also handles configuration files and scripts that are included with the package.

How is dpkg different from other package managers?
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.
