Which of the following are ways for transmitting data at the Ethernet level? (Select all that apply)1 pointDuplexBroadcastMulticastUnicast

Breakdown of the Problem

To determine which options are valid ways of transmitting data at the Ethernet level, we need to understand each term—Duplex, Broadcast, Multicast, and Unicast—within the context of Ethernet networking.

Relevant Concepts

1. Duplex: This refers to the ability to send and receive data at the same time (full-duplex) or only one direction at a time (half-duplex). It is not a data transmission method per se but rather a mode of operation.

2. Broadcast: This method sends data packets to all devices on a network segment. It is a standard way of data transmission in Ethernet networks.

3. Multicast: This method targets a specific group of devices on a network, allowing the sender to send data to multiple receivers efficiently.

4. Unicast: This method involves a one-to-one communication between a sender and a single receiver.

Analysis and Detail

1. Duplex - Not a data transmission form but an operational mode.
2. Broadcast - Valid; sends data to all devices in the network.
3. Multicast - Valid; sends data to a specific group of devices.
4. Unicast - Valid; sends data to a specific device.

Verify and Summarize

After analyzing each term, we can summarize the findings:

• Duplex is not a method of transmitting data but rather describes the functionality of the connection.
• Broadcast, Multicast, and Unicast are indeed valid data transmission methods at the Ethernet level.

Final Answer

The valid ways for transmitting data at the Ethernet level are:

• Broadcast
• Multicast
• Unicast
