duplex operation การใช้

• :Depends on if your sound card supports full duplex operation or not.
• However, half-duplex operation for gigabit speed isn't supported by any existing hardware.
• The use of two separated frequency bands made full duplex operation possible.
• Many scanners can scan both sides of double-sided originals ( duplex operation ).
• In the half-duplex operation, both stations may transmit, but only one at a time.
• In normal half-duplex operations late collisions do not occur.
• In full duplex operation, both stations may transmit simultaneously.
• It provides for either half-duplex operation and provides synchronization points in the stream of exchanged messages.
• Full-duplex operation makes teleconferencing more like face-to-face conversation.
• In half-duplex operation of a type A polarential system, the direct-current balance is independent of line resistance.
• The standard supports only full-duplex operation.
• In half-duplex operation of a type B polarential system, the direct current is substantially independent of the line leakage.
• In December 1972, Vadic introduced the " VA3400 ", notable for full-duplex operation at 1, 200 bit / s over the phone network.
• Some regular office phones offer only half-duplex operation : if one party is talking, the people listening can't respond until the first party finishes.
• While many of the marine HF channels are full duplex ( different transmit frequency for ship and ground station ), few ships had the radio & antenna capability for duplex operation.
• Collisions are only recognized on UTP when the station is operating in full-duplex operation in this regard is whether or not the transmit and receive pairs are permitted to be used simultaneously.
• Some datasets support full-duplex operation, and full-duplex ( 4-wire ) can be used in many circumstances to improve performance by eliminating the turn-around time, at the added expense of 4-wire installation and support.
• Some computer-based systems of the 1960s and 1970s required full-duplex facilities, even for half-duplex operation, since their poll-and-response schemes could not tolerate the slight delays in reversing the direction of transmission in a half-duplex line.
• The Catalyst 2900 Series XL switches are based on an advanced architecture that offers a three-million packet-per-second forwarding rate and a 1.6-gigabitper second ( Gbps ) forwarding bandwidth to deliver wire-speed performance for up to 16 ports in full-duplex operation.
• The Catalyst 2900 Series XL switches are based on an advanced architecture that offers a three-million packet-per-second forwarding rate and a 1 . 6-gigabitper second ( Gbps ) forwarding bandwidth to deliver wire-speed performance for up to 16 ports in full-duplex operation.
