If you are in the process of learning more about the world of information technology or cybersecurity, you’ve probably heard talk about the Linux Operating System. Unfortunately, in my experience, everyone made it appear to be an extremely POWERFUL and COMPLEX Operating System that only the most elite hackers in the world could use. If you’re anything like me, you were intimidated by it.

That was me nine years ago, and at that time, I had already been working in I.T. for 13 years, and I had never had to work with a Linux machine up until that point. However, this will be different from the experience people venturing into the I.T. world will have going forward. In the last ten years, even the last five years, Linux has grown significantly.

From IoT and Mobile Devices to Desktops and Servers, Linux is finding more ways to be utilized. Of course, we can’t guarantee you will come across a Linux device anytime soon, but at this point, you may have walked past a Linux device or two without realizing what it was.

Setting any worry or fears aside, I had to dive right in and start learning what I could about Linux. So I’m going to save you all the trouble I had about figuring out the best way to understand this operating system and jump right into an absolute game changer when it comes to learning almost every operating system available.


With free programs and applications like Virtual Box available, it’s possible to utilize your existing computer to VIRTUALIZE a “second computer” or a Virtual Machine. You can download a free Linux Operating System version like Ubuntu, and immediately jump headfirst into something new and exciting.

Hands down, the easiest and safest way to learn more about Linux is to virtualize it, and when you do this, you will find that it’s not as intimidating as you thought it was. As you’ll discover, some of the modern Linux Distribution GUIs(Graphical User Interfaces) resembles Apple’s Mac OS.

Whether you are just getting started in the technology world or looking to improve your skills, having the ability to virtualize an additional or separate operating system can offer a limitless world of opportunity when it comes to learning new skills. The most significant benefit from a learning standpoint is that when you make a mistake in a virtual machine, it doesn’t affect your Host machine, and you can easily spin up another Virtual Machine and pick up where you left off. Virtualization makes mistakes much more forgiving, creating a much more enjoyable learning experience.

I’m happy to share that after the first time spinning up a Linux Virtual Machine nine years ago, I was no longer afraid to get my hands on new technology and begin the learning experience.
