BIOS basic input/output system—BIOS functions are the fundamental level
of any PC or compatible computer. BIOS functions embody the basic
operations needed for successful use of the computer’s hardware
resources
buffer temporary storage for acquired or generated data (software)
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
C
C Celsius
channel pin or wire lead to which you apply or from which you read the analog
or digital signal. Analog signals can be single-ended or differential. For
digital signals, you group channels to form ports. Ports usually consist
of either four or eight digital channels
CIS card information structure
clock hardware component that controls timing for reading from or writing to
groups
CMOS complementary metal-oxide semiconductor
counter/timer a circuit that counts external pulses or clock pulses (timing)
coupling the manner in which a signal is connected from one location to another
CPU central processing unit
crosstalk an unwanted signal on one channel due to an input on a different
channel
current drive capability the amount of current a digital or analog output channel is capable of
sourcing or sinking while still operating within voltage range
specifications
current sinking the ability of a DAQ board to dissipate current for analog or digital
output signals
