Freeware - software you do not have to pay for (e.g. Google Chrome)
Open-source software - software whose code you can inspect
Free software - software you can use, modify and share
FOSS - software that satisfies the second and third condition (e.g. lemmy, linux, VLC)
While almost all free software is also open-source, there are a few exceptions like some early versions of Mozilla Firefox. There are quite a few open-source software that are not free software, such as Android.
