Data acquisition From Wikipedia
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...

Introduction to Data Acquisition (DAQ)
The simplest way to store data is to record it on paper with either a strip-chart recorder or an x-y plotter.
For greater utility, most modern analytical instruments digitize data in digital format for subsequent data storage, analysis, and presentation.
For some types of instruments, such as Fourier-transform-based spectrometers, digitized data is necessary for the data manipulation to extract the spectrum from the raw data.

Technical Notes: Communication Links
Data acquisition hardware comes in many physical formats.
A common type is the plug-in card which fits into a free expansion slot in the computer.
Its main advantages are its low cost and its speed.
Its main drawbacks are the limited potential for system expansion and the fact that the computer has to be located close to the signal source.
Microlink systems solve these problems by offering an extensive range of external data acquisition hardware.
