| The MAC driver (Media Access Control Driver) |
| |
| The second layer of OSI (Data-link layer) is divided into two sublayers by the Institute of Electrical and Electronic Engineers Inc (IEEE) project 802-MAC and LLC sublayers. |
| |
| A MAC driver is the device driver located at the MAC sublayer. |
| |
 |
| |
| A MAC driver provides low level access to network adapters by providing data transmission support and some basic adapter management functions. |
| |
| These drivers also pass data from the physical layer to network protocols at the network and transport layers |
