LAN Technologies: Broadcast, Collision, CSMACD and CSMACA This lesson discusses the technologies of Local Area Networks (LANs). The technologies of Local Area Networks include:
- Broadcast: sends to all, only on one side of router
- Collision: two devices transmit simultaneously, data on same line collides and corrupts, there needs to be ways to avoid collisions.
- CSMA/CD: carrier sense, multiple access, collision detection.
- CSMA/CA: carrier sense, multiple access, collision avoidance
