Yarn can install packages from local cache. [8] Yarn binds versions of the package strongly. Yarn uses checksum for ensuring data integrity, while npm uses SHA-512 to check data integrity of the packages downloaded. [9] Yarn installs packages in parallel, while npm installs one package at a time.
A package manager deals with packages, distributions of software and data in archive files.

dpkg-source packs and unpacks the source files of a Debian package. dpkg-gencontrol reads the information from an unpacked Debian tree source and generates a binary package control package, creating an entry for this in Debian/files. dpkg-shlibdeps calculates the dependencies of runs with respect to libraries.
At that time, package installation involved the source code being downloaded and compiled on the end user's machine. Version 2.0, released in 2011, introduced support for prebuilt binary archives; by default ports are installed using the prebuilt binary archive if available, and are built from source otherwise.
One option is to force a particular version of a package. This can downgrade a package and render dependent software inoperable, so the user must be careful. Finally, the apt_preferences mechanism allows the user to create an alternative installation policy for individual packages. The user can specify packages using a POSIX regular expression.
Spec files end in the ".spec" suffix and contain the package name, version, RPM revision number, steps to build, install, and clean a package, and a changelog. Multiple packages can be built from a single RPM spec file, if desired. RPM packages are created from RPM spec files using the rpmbuild tool.
