The Introduction to Data Networking and TCP/IP course presents the basic theory of network hardware and software. The course starts with the OSI reference Model and data structure that explains the Ethernet protocol and LAN switching. We continue focusing on TCP/IP, from the basics of IPv4 and IPv6, through TCP and UDP, to application protocols that build the Internet.
