Network Administrator Essentials is a foundational course in networking concepts and technologies and does not require that you have any understanding of networking before you start this course of study. However, you should be familiar with the configuration and operation of computer systems prior to taking this course. If you currently do not have this basic understanding of computers, we recommend that you complete our CompTIA IT Fundamentals Certification course before you start Network Administrator Essentials.
