DAQ (Data AcQuisition) is the process of bringing a real-world signal into the computer, for processing, analysis, storage and data manipulation. Today, most scientists and engineers are using personal computers with ISA, EISA, PCI or PCMCIA bus for data acquisition in laboratory to test and measurement, and industrial automation. Many applications use plug-in boards to acquire data and transfer it directly to computer memory. Others use DAQ hardware by using the Personal Computers (PC) that is coupled via parallel port, serial port or GPIB-Bus.
