The network layers

Learn about the layered nature of computer networks, including the OSI model. You will learn about routing, switching and specific information transport equipment in order to understand the Domain Name System and DNSSEC mechanisms. You will then know how to secure a network while guaranteeing the quality of service, or QoS.
