Fastra II is a computer program that helps people learn a new language. It works by breaking down a language into smaller pieces like words and sentences, then showing the user how to put them together. It also includes activities like quizzes and games to help the user understand and remember what they're learning. Fastra II is like a teacher, but in a computer program instead of a person - it's perfect for people who want to learn a language without having to hire a real teacher.
