Operating systems form the backbone of every computer environment, and this episode gives you a high-level tour of the first domain in Core 2. We explain what operating systems do—managing files, memory, processes, and users—and how the exam tests your ability to install, configure, and maintain various OS platforms. Windows takes center stage, but macOS, Linux, Android, and Chrome OS are also part of the curriculum.

We also discuss how this domain blends technical knowledge with user support, covering concepts such as system utilities, configuration panels, file permissions, and compatibility considerations. You’ll walk away with a clear understanding of what topics to prioritize and how they fit into everyday IT support roles. This is the foundation for many of the Core 2 episodes to come.
