Introduction to Networking Training

This hands-on Introduction to Networking course will enable you to take a more active part in the discussion and decision-making processes related to networking technology issues. You take your first step towards networking and data communications exposure, and gain the practical knowledge and skills to become comfortable with basic concepts, technologies, components, and design alternatives. You learn to implement networks using data links and physical media, deploy LANs using Ethernet and Wi-Fi, and build reliable internetworks and intranets using proven TCP/IP design techniques.
