Introduction to TCP/IP (Part 2) - Five Layer Model and Applications


In this self-paced training, you will learn about the 5 layer TCP/IP software model. We’ll start at the Application layer and work our way down through the Transport, Network, Data Link, and Physical layers. When we get to the Transport layer, we will discuss the differences between TCP and User Datagram Protocol (UDP) and explain why specific applications use one instead of the other. We will also briefly describe some common TCP/IP applications (HTTP, DNS, DHCP, etc…).
