等时传输：这些是实时的数据流，它们对带宽的要求高于可靠性要求。
Isochronous transfers: These are data streams in real time with higher requirements for bandwidth than for reliability.
千兆网络很少将其所有的带宽用于一个单独的数据流；相反，他们允许大量低速的传输同时进行。
Gigabit networks will seldom devote all of their bandwidth to a single data stream; instead, they will allow enormous Numbers of lower-speed transmissions to proceed simultaneously.
然而，为了让iMic具有适度的性能，我们在本系列文章中的目标是处理两个并行的(立体声)44.1 kHz的16位数据流，这就意味着要实现22.05 kHz的音频带宽。
However, in line with the modest capabilities of the iMic, our target for this series is to work with two parallel (stereo) 44.1khz 16-bit data streams, implying an audio bandwidth of 22.05khz.
