1. :Depends on if your sound card supports full duplex operation or not. 2. However, half-duplex operation for gigabit speed isn't supported by any existing hardware. 3. The use of two separated frequency bands made full duplex operation possible. 4. Many scanners can scan both sides of double-sided originals ( duplex operation ). 5. In the half-duplex operation , both stations may transmit, but only one at a time. 6. In normal half-duplex operations late collisions do not occur. 7. In full duplex operation , both stations may transmit simultaneously. 8. It provides for either half-duplex operation and provides synchronization points in the stream of exchanged messages. 9. Full-duplex operation makes teleconferencing more like face-to-face conversation. 10. In half-duplex operation of a type A polarential system, the direct-current balance is independent of line resistance.
