redistributed across the remaining active adapters in the team. See also
teaming .

interactions with diskette drives, hard disk drives, and the keyboard.

bits per second (bps). The rate at which bits are transmitted per second. Contrast with baud .
bps. See bits per second.
buffer. See buffer storage .
buffer storage. (1) A special-purpose storage or storage area allowing, through temporary storage, the data transfer
between two functional units having different transfer characteristics. A buffer storage is used between
non-synchronized devices, a serial and a parallel device, or between devices having different transfer rates. (2) In
