TYPO3 is famous for its multilingual abilities. TYPO3 3.8.0 is available in 43 different languages. In TYPO3 3.8.0 each language is represented by an extension. So if you need a new language for backend or frontend you only install another language extension. In order to keep the software more compact these language extensions are no longer shipped by default.
Hint: The needed language extensions are named csh_[language code].
System extensions is an expression for fundamental extensions in TYPO3. All extensions that are now considered "System extensions" are included in the folder typo3/sysext/.
