The Wikipedia translator -- very useful for technical translations. Harnesses the vast amount of cross-lingual information on Wikipedia and Wiktionary, and present it in a neat, time-saving way. Simple user interface. Built for translators, by a translator, but is a generic tool for anyone who wonders what a word or phrase means, which language it is and what it is in other languages. All Wikipedia languages (currently 292).
Human translation: Human translation is performed by people who are fluent in the language pair being translated. The whole process, from translation to proofreading, is performed by people. This type of translation is generally more accurate than machine translation since the humans who translate will account for nuances and cultural context. Because of this, though, it takes longer than machine translation.
