Configure a Switch. LAN Switching and Wireless – Chapter 2 Sandra Coleman, CCNA, CCAI. Objectives. Summarize the operation of Ethernet as defined for 100/1000 Mbps LANs in the IEEE 802.3 standard. Explain the functions that enable a switch to forward Ethernet frames in a LAN.

The devices that were involved in the collision do not have priority to transmit data.
(JAM) When a collision occurs, each node that is transmitting will continue to transmit for a short time to ensure that all devices see the collision.
Half-duplex – uses CSMD/CD
-Walkie-talkies, CB Radios – only one person can talk at a time. Data can only flow in one direction at a time.
Full-duplex – no collisions because use different channels to send and receive. Must have a switch, NICs that support it.
