What it is	Computer Science I is an introductory computer science program where you learn programming, algorithms, and core computational concepts. It differs from some other programs because it includes a mandatory co-op component, giving you paid work experience in tech roles alongside your studies. This program suits students who want hands-on industry experience early and are curious about whether computer science matches their strengths before committing to upper-year specializations.	You study how to protect computer systems and networks from cyberattacks by learning programming, software design, and artificial intelligence techniques. Unlike a general computer science degree, this program is built around real-world security problems and includes a co-op work term, so you apply what you learn in actual jobs while still studying. It suits people who want hands-on technical experience and are interested in the growing field of protecting digital information.	You study how to design, build, and maintain large software systems using engineering principles and mathematics. This co-op stream requires you to alternate between classroom terms and paid work terms in industry, giving you real project experience alongside your degree. It suits people who want hands-on experience, enjoy problem-solving with code, and are ready to balance school with regular full-time work placements.
