The BitTorrent protocol is used for peer to peer file sharing and it's an extremely efficient way of downloading and sharing files with groups of people. While file sharing with BitTorrent is normally associated with video files like movies or TV episodes, it's also common for Linux developers to offer a torrent download of their distribution.

Torrents are great for downloading large files because they are split into smaller chunks and downloaded from multiple peers in the torrent "swarm." Being able to download from a lot of different sources simultaneously should mean that your download bandwidth is completely saturated, resulting in a very quick download of large files. When all of the file chunks are done downloading, the file is reconstructed automatically.

In order to download something via BitTorrent, you need to have a torrent client installed on your system. On Ubuntu 20.04 Focal Fossa, there are quite a few options to choose from. Some have a graphical interface and some only work on the command line, but they all have their advantages and quirks.

As you probably know, tons of software can be installed in Ubuntu 20.04 right from the command line via apt or from the Ubuntu Software application on Ubuntu's desktop. The way this works is that Ubuntu will query a repository which contains links to the various software you may wish to install. It searches for the package you specify, and then downloads and installs it.

Although Ubuntu's default package archive contains some of the most common software people need, a lot of times it's necessary to install a package using a PPA repository. No problem there, except these PPA repositories don't remove themselves unless you do it manually. After a while, your system could be querying a lot of irrelevant PPA repositories every time you install or update software.
