[[!meta title="The terms FOSS and the relation to FS, OSS and FLOSS"]]
## Introduction
Today, there are different terms in use to describe ***free*** and
***open source software***. This article gives you a short overview
about those terms and a short reason why I prefer to use ***FOSS***.
### Free software
[GNU](http://www.gnu.org) prefers to use the term
"Free software".
The reason for me not to use this term are:
- The abreviation is "FS", which is ambiguous. "FS" is often used as the abreviation for "filesystem".
- The term does not tell you directly, that you also have access to the source (main reason one).
- I think people can easily think free software is just free as in "nothing to pay for it" (main reason two).
- I do not like to pronounce it. Think about "I've like effess." Nothing my tongue likes.
### Open source software
I liked to use the term "Open source software"
some time. Perhaps because it was used often to talk about what I
associate with GPL'ed or BSD-licensed software. But then, one day, I
found out about the above mentioned GNU free software definition and I
began to think about both terms. In contrast to free software, open
source software (OSS) is much more known, but my reasons not to use it
are:
- It lacks the "free as in copy it as you like" definition (main reason).
- I think about the "Open sound system", if I read "OSS", which is not what I want to talk about.
## Free and open source software (FOSS)
The simplest solution is to combine both terms and finish all problems.
So using FOSS, I get the following advantages and disadvantages:
- It is neither an abreviation for "filesystem" nor "open sound system".
- I can pronounce it: "foss."
- It is short and simple and contains everything I love about FOSS.
- Other people may not like it, because I introduce yet another acronym.
- It combines the two terms of both "worlds", so everyone can be happy.
