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. In this course, you'll review how to identify physical layer connectivity options. You'll learn three types of MAC addresses and how to identify different Ethernet frame formats and modifications. You'll also explore the header fields of Ethernet and how they are used, as well as modifications of the Ethernet frame format. Finally, you'll learn about the use of protocol analyzers. In order for internetworking to work, there has to be a way to distinguish which network a device belongs to. This is accomplished with a form of addressing called logical addressing, which is presented by an IP address. In this course, you'll also learn the evolution of IP addressing from classical addressing through class-less addressing. You'll examine how network masking operates. Finally, you'll explore network address translation and the value of variable length subnet masking. This course was originally created by Global Knowledge (GK).
