Since we received positive feedback about the republication of our post What is a CAT tool here on the Transit/TermStar NXT Tooltips, I decided to continue to republish a series of articles from our blog Globalízate about basic concepts of computer assisted translation. These articles do not verse specifically about Transit or TermStar, but they might be a good starting point for newcomers or first time users to get a grasp of some of the fundamentals of the technology. They also provide technical authors or more generally content creators with clues about what they should bear in mind when writing for an international audience, i.e. write content that is going to be translated. So without further ado, here it is, I sincerely hope you enjoy it.
