GPIB (general purpose interface bus) is a parallel port device. it can transmit more than one bit at a time. it is faster than rs 232 port. which is a serial port can transmit one bit at a time.the only disadvantage of GPIB or parallel port is it require more transmission bit so its transmission distance reduces.

A GPIB (otherwise known by its full name General Purpose Interface Bus) can be used for a number of purposes. Technical instrumentation such as as measuring devices and data communications is its primary purpose to connect to a computer.

HP is a company that makes and market particular hardware / software for speciallist application. An example is the 12C calculator which is capable of using a GPIB standard chip to send a signal through a RS485 cable to a computer

The CRO can be interfaced to the Computer in many ways. 1. GPIB network:A NI-PCI-GPIB card is inseted in any PC slot of computer and it is interconnected to the CRO GPIB port.The CRO control and measurements can be performed using LabVIEW. 2.Now a days Computer inbuilt CRO's are available in the market form Tektronix ,Agilent etc. 3.You can interface CRO to the computer through LAN, using necessary drivers etc. Regards Ranga

General Purpose Interface Bus. It was developed by Hewlett Packard primarily as a communications link for test instruments.
