In this section, you will learn about the parts of the Ethernet frame, as shown in Figure and how internetworking devices such as routers and switches filter and forward these frames. There are several different types of Ethernet or IEEE 802.3 frames. The terms “Ethernet” and “IEEE 802.3” are similar but not identical. Ethernet is a product name and a competing standard with IEEE 802.3. There are some differences and similarities, but for the purposes of this section they are not important. To keep things simple, you will see the term “Ethernet” throughout this section, however, the information applies to both Ethernet and IEEE 802.3 protocols.
