Figure 9.2 |
The general format of a frame sent across a LAN. The header contains information such as the addresses of the sender and the recipient. |

Figure 9.3 |
Illustration of the frame format used with Ethernet. The number in each field gives the size of the field measured in 8-bit octets. |

Figure 9.4 |
Examples of frame types used with Ethernet (type values are given in hexadecimal). The table lists only a few examples; many other types have been assigned. |

Figure 9.6 |
An example of the 8-octet IEEE LLC/SNAP header, which is used to specify the type of data. The SNAP portion specifies an organization and a type defined by that organization. |
