Learn The Fundamentals of Computer Networking
Networks are systems of interconnected computers, and increasingly other devices. They can be smaller scale, such as a home network, or large scale, such as found in large corporations and governments. As so many different devices can be interconnected in networks many computer problems can be traced back to network issues. Understanding how networks operate and how to resolve problems is a desirable skill to possess.
This course teaches these fundamental aspects and how to maintain them and troubleshoot problems. This course is a great introduction to anyone hoping to work as a network engineer, or for IT engineers wanting to improve their skillset.
Course Duration: 100 hours of study. Self-paced.
