What it is	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	You study how to design, build, and maintain software and computer systems. This program covers programming languages, algorithms, data structures, and how computers work at a fundamental level. If you choose the co-op stream, you'll alternate between studying and working at tech companies, giving you real professional experience alongside your degree.	You study the theory and practice of computer programming, software design, and how to build applications and systems. The co-op option lets you alternate between school terms and paid work terms at companies, giving you real workplace experience alongside your degree. This program suits people who want to combine hands-on coding skills with an understanding of how software works in actual business and technology settings.
