The QS World University Rankings by Subject 2020 features 601 of the world's top universities in computer science.

Four different sources are used to compile the rankings: academic reputation, employer reputation, research citations per paper, and H-Index (which is used to measure the productivity and impact of a university), according to the rankings methodology.

The top computer science universities in each region around the world are described here.
