BNC
a type of coaxial signal connector
buffer
temporary storage for acquired or generated data
burst-mode
a high-speed data transfer in which the address of the data is sent followed
by back-to-back data words while a physical signal is asserted
by back-to-back data words while a physical signal is asserted
bus
the group of conductors that interconnect individual circuitry in a computer.
Typically, a bus is the expansion vehicle to which I/O or other devices are
connected. Examples of PC buses are the PCI bus, AT bus, NuBus, Micro
Channel, and EISA bus
