1. Half - duplex mode applies to end the conversation between the terminal and communication.

2. In half duplex mode the transmission is looped back to receive.

3. The working mechanism of data radio transceiver is introduced briefly, which communicates with computer serial port via RS - 232 and adopts four - wire half duplex mode.

4. Network access was through a single one-GB Ethernet adapter, running in full duplex mode.

5. With the expansion and development of the Internet, various net impediments appear. This paper discusses the phenomenon and the principle of the impediment caused by unmatched duplex mode.

5.

6. By default, the FE electric interface operates in full duplex mode.

7. When the gigabit ethernet work on UTP, it must adopt the 4pairs UTP at the full duplex mode, and need to increase some new requirement of performance parameters return loss , NEXT, PSNEXT.

8. The UTP Ethernet variants support an additional autoconfiguration protocol that allows two Ethernet systems to negotiate which speed to use, in full or half duplex mode.

9. Network access was through a single 1 GB Ethernet adapter, running in full duplex mode.

10. The mail databases were spread across five IBM FAStT 600 arrays, also RAID 0. Network access was through a single 1 GB Ethernet adapter running in full duplex mode.
