Computer networking expertise is a highly in-demand field. Understanding the ways that different devices communicate across a network, knowing how to ensure that those devices remain safe from intrusion of outside forces, and making sure that these technologies interoperate in a way that facilitates your organization’s success is an incredibly in-demand skill. But becoming a networking professional can seem like a bit of an arduous path. There is a lot to learn and surely it must be expensive to take courses that will provide the training you need to succeed.

Fortunately, that’s not entirely true. While learning the skills needed to be a networking professional can be a challenging undertaking, it doesn’t have to be expensive. The Internet is filled with many different free online networking courses that can help you to get started on your journey towards a new career as a networking professional. No longer is it a requirement to sink a ton of time and money into costly networking programs.

Finding a free online networking course that suits your needs is a great, low-impact way to take the first steps towards a new career path. That is why we’ve compiled this list of some of our favorite free online networking courses for you to browse.
