Definition: Data acquisition is the sampling of the real world to generate data that can be manipulated by a computer.
Sometimes abbreviated DAQ or DAS, data acquisition typically involves acquisition of signals and waveforms and processing the signals to obtain desired information.
The components of data acquisition systems include appropriate sensors that convert any measurement parameter to an electrical signal, which is acquired by data acquisition hardware.
Acquired data are displayed, analyzed, and stored on a computer, either using vendor supplied software, or custom displays and control can be developed using various general purpose programming languages such as BASIC, C, Fortran, Java, Lisp, Pascal.
Specialised programming languages used for data acquisition include, EPICS used to build large scale data acquisition systems, LabVIEW, which offers a graphical programming environment optimized for data acquisition and MATLAB provides a programming language but also built-in graphical tools and libraries for data acquisition and analysis.
