  • 6. Original Ethernet Standard
  • 7. CSMA/CD ■ 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. ■ If a collision still occurs, the devices that caused the collision wait a random amount of time and then try again.
  • 8. UTP Cabling
  • 9. LAN Addressing LAN Addressing Term or Feature Description Media Access Control. 802.3 (Ethernet) defines the MAC MAC sublayer of IEEE Ethernet. Other names often used instead of MAC address. These terms Ethernet address, NIC address, LAN address describe the 6-byte address of the LAN interface card. Burned-in address The 6-byte address assigned by the vendor making the card. Unicast address A term for a MAC that represents a single LAN interface. An address that means “all devices that reside on this LAN Broadcast address right now.” On Ethernet, a multicast address implies some subset of all Multicast address devices currently on the Ethernet LAN.
