yum: Updates and Installs Packages 848

Apt: An Alternative to yum 850

BitTorrent 855

Apt and yum both fill the same role: They install and update software packages. Both utilities compare the files in a repository (generally on the Internet) with those on the local system and update the files on the local system according to your instructions. Both utilities automatically install and update any additional files that a package is dependent on. Apt is slightly faster, especially over slow connections, and it supports a few more features, such as undoing upgrades. The yum utility is easier to configure and use than Apt. If you are familiar with Debian systems or find that yum lacks some features you need, try using Apt; otherwise use yum. The examples in this section are from a Fedora Core system; although the files, input, and output on your system may look different, how you use the tools and the results will be the same.

Contrasted with Apt and yum, BitTorrent efficiently distributes large amounts of static data, such as installation ISO images. It does not check files on the local system and does no dependency checking.
