A master’s in computer science is graduate study of computing at an advanced level. Core topics usually include algorithms, systems, and software engineering, with electives in areas like AI, data science, cybersecurity, and distributed systems.
Graduates work as software engineers, data scientists, machine learning engineers, and systems architects. The degree can help with promotions into senior and research roles, and it is a common stepping stone to a PhD.
Programs come in several shapes. Coursework-only tracks suit working professionals. Thesis tracks suit those aiming at research or doctoral study. Online options exist for both, which helps people who cannot relocate.
