Ethernet Network Access and IPv4 Addressing

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.áThis course was originally created by Global Knowledge (GK).á
