Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.

Data acquisition I/O modules or cards have both input and output functionality.

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus

Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes

Data acquisition input modules accept sensor and other signal output for data acquisition systems.

Video cards are used to regulate the data displayed on computer monitors.

Counter and timer boards are computer cards that perform digital counting and/or timing functions
