Virtual Instrument Software Architecture (VISA) allows communication between a computer and an instrument to be controlled by the same software regardless of the physical interface. It is also referred to as VISA library or VISA communication.

The Interfaces connecting computers to measuring instruments include LAN, USB, GP-IB, and RS-232C. As the interfaces vary in shape and configurations, different computer software for each had to be prepared.

Using multiple interfaces simultaneously took a lot of work, time, and expertise.

VISA communication gave the communication solution. VISA communication is available with the same software regardless of the interface type, so there is no need for separate libraries or separate software for each. The VISA can reduce labor and make it easier to handle multiple devices simultaneously.

However, some interfaces and devices are not supported and require individual settings.
