If you are a “regular” desktop user, then using a graphical user interface (GUI) to compress and decompress archives is going to be enough most (if not all) of the time.

In relation to package management, that is something you will use very frequently both as a regular desktop user and as a software engineer (or some other career choice) using Linux, so do pay close attention.
