Expected Duration
162 minutes

You will understand the importance of the services, features, and protocols at the Application, Transport, and Internet Layers. This course focuses on the Internet Layer, Transport Layer and Application Layer of the TCP/IP stack. It will cover topics such as IPv4 addressing, binary, TCP vs UDP, and port numbers. It will also introduce you to Syslog.
