My Review of the Intro to Computers and OS Security Quiz Answers

I recently completed the “Introduction to Computers and Operating Systems & Security” course on Coursera, which is part of the Microsoft Cybersecurity Analyst Professional Certificate. This course is a great starting point for anyone curious about cybersecurity or aiming to break into the field with no prior experience.

It’s designed to build foundational knowledge around computer systems, operating systems, enterprise environments, and basic cybersecurity concepts.

The course is divided into four modules, each introducing key components such as hardware, how computers interact with operating systems, the cybersecurity landscape, and different business computing environments.

What I liked most was how beginner-friendly and clearly structured the content was, making it easy to follow even without a technical background. It effectively bridges the gap between basic computer knowledge and the more advanced topics you’ll encounter later in the cybersecurity field. If you’re considering a career in cybersecurity, this course is a helpful first step — and in this blog post, I’ve also included the quiz answers to support fellow learners as they work through the material.
