=====Background=====

====What is an archive====
a place where data is collected, preserved, managed, and made accessible to those with permission; although many are public.

in the context of Linux, an archive is a place to store as many folders / files as one needs into one centralized file for long-term use.
====What actions can be performed on an archive?====
an archive can be compressed to be smaller
====What is compression====
the proccess of encoding data into fewer bits than the original representation
====How does compression differ from archiving?====
archiving doesn't reduce file size, while compression does.
====Types of compression (lossy vs lossless)====
after compressing a file with a lossless technique, the original image before it was compressed should look exactly the same after it is decompressed. Lossy compression makes a file lose data everytime it is compressed and decompressed.
