This is the software repositories that you will meet with some linux os. They are used to download your software in opposition to compiling them from source. In other words they automatate every thing for the dumb shit you are and allow you to install, update and remove the application you need cause youre to retarded to write them by yourself with a magnifying glass and the sun directly on your hard drive. The most common package managers are yum (RHEL - rpm) and apt (Debian - deb).

apt

You run it like this:

To install: sudo apt-get install <package>

To update: sudo apt-get update <package>

To remove: sudo apt-get remove <package>

To remove unneeded dependencies: sudo apt-get autoremove

yum

to install: sudo yum install _________
