A polyglot is someone who:

can speak several languages.
has traveled internationally.
has excellent self-management skills.
understands low-level programming languages.

All four statements are correct. A polyglot is someone who can speak several languages, indicating proficiency in multiple languages. They have the ability to communicate effectively in different linguistic contexts.

While it is not a defining characteristic of a polyglot, many polyglots do tend to have experience in international travel. This exposure to different cultures and languages can contribute to their language learning abilities and deep understanding of various languages.

Having excellent self-management skills is not directly related to being a polyglot, but individuals who are dedicated to learning multiple languages often possess traits like discipline, organization, and motivation, which are components of good self-management.

Understanding low-level programming languages, such as assembly or machine code, is another trait that can be associated with being a polyglot. Just as a polyglot can speak multiple languages fluently, they may also possess the ability to understand and work with different programming languages, including low-level ones.
