Basically, the CSMA/CD algorithm can be summarized as follows:<p> |
|||
MAC <p> Definitions: Media Access Control 802.3 (Ethernet) defines the MAC sublayer of IEEE Ethernet. <p> |
|||
• A device that wants to send a frame waits until the LAN is silent – in other words, no frames are currently being sent – before attempting to send an electrical signal.<p> |
|||
Ethernet address, NIC address, LAN address <p> Definitions: Other names often used instead of MAC address. These terms describe the 6-byte address of the LAN interface card. <p> |
|||
• If a collision still occurs, the devices that caused the colision wait a random amuont of time and then try again. |
|||
Burned-in address <p> Definitions: The 6-byte address assigned by the vendor making the card. <p> |
|||
Unicast address <p> Definitions: A term for a MAC that represents a single LAN interface. <p> |
|||
Broadcast address <p> Definitions: An address that means "all devices that reside on this LAN right now." <p> |
|||
Multicast address <p> Definitions: On Ethernet, a multicast address implies some subset of all devices currently on the Ethernet LAN. <p> |
