This course will review how to identify physical layer connectivity options. Technically, the network interface layer of the TCP/IP model is not described in the family of protocols, but an IP packet cannot travel between devices without using physical media and protocols to access that media so it’s necessary to understand these concepts. This course will cover three types of MAC addresses and how to identify different ethernet frame formats and modifications. You'll also review the header fields of ethernet and how they are used and you'll be able to list modifications to the ethernet frame format. Finally, you'll learn to explain the use of protocol analyzers.
