What is the “virtual” GPIB connection?

TekVISA support for an internal resource called virtual GPIB means fast connectivity between Windows and the embedded software side of your oscilloscope. Virtual GPIB provides a software bridge to and from embedded oscilloscope software, permitting direct internal access to the oscilloscope for much faster and larger acquisitions than conventional GPIB ports. What is more, this feature facilitates remote connections with other PCs over a standard Ethernet LAN without the need for special GPIB-to- LAN hardware adapters.
