Windows, macOS & Linux Fundamentals

About this course

This course introduces the three major operating systems covered on the CompTIA A+ Core 2 exam — Windows, macOS, and Linux — with a focus on how each is installed, configured, and used in real-world IT support environments. Learners benefit from building solid OS literacy across all three platforms, including how to navigate interfaces, manage files, and understand the foundational roles of power supplies and storage in a working system. Hands-on online labs put these skills into practice through guided, scenario-based exercises.
