What is used to determine when the communications channels are clear and when a device is free to transmit data Ethernet?We generally abbreviate this to CSMA/CD. CSMA/CD is used to determine when the communications channels are clear and when the device is free to transmit data.
What is a device that knows how do you forward traffic between independent networks?A router connects independent networks by forwarding data between them.
What is the transmission method that sends data to every device on a LAN?Broadcast. Broadcast is a one-to-all transmission method in which the network carries a message to all devices at the same time, as illustrated in Figure 6-5.
Which layer is responsible for defining a common way of interpreting the signals so network devices can communicate?While the physical layer is all about cabling, connectors and sending signals, the data link layer is responsible for defining a common way of interpreting these signals, so network devices can communicate.
