Difference between Translation Memory, Termbase and Machine Translation
Termbase: Contain entries which usually are translations of words (entries) in two or several languages.For example:
Entry #2103:
└English: challenge
└Japanese: チャレンジ
└Japanese: 挑戦
└Vietnamese: thử sức
└Vietnamese: khiêu chiến
Translation Memory: Store pairs of sentences in 2 languages (source language and target language).
For example TM with Japanese as source language and Vietnamese as target language:
┌Source text: 先に失礼します。You must translate yourself these sentences for the first time (e.g. human translation).
└Target text: Tôi xin phép về trước ạ.
Machine Translation: Translation done by machine e.g. automatic translation (not human translation).
You can see detail explanation in FAQ about TM below.
