It spans the data link and network layers of the OSI model as shown in Figure 16.1. The network driver needs to match the specific hardware configuration of the network card such as its addresses of I O ports control and status registers etc. Ethernet cards use the same IEEE 802.3 protocol so they can communicate with one another but each needs a unique driver because of the different vendor hardware implementations. 16.1.2 Compatibility and usage The network driver must also be compatible with the appropriate network operating system protocols in the network transport and session layers that are used to send data 244 Practical TCP IP and Ethernet Networking across the network. In early systems changing from one network protocol to another e.g. TCP IP to SPX IPX generally necessitated changing the network driver. The network operating systems communication protocols and their relationship to the OSI model are shown in Figure 16.1.
