OverviewA virtual device is an abstraction built on one or more real devices. The correspondence between a virtual device and a real device is many-to-many, but not all combinations can be defined or supported by the kernel. Some of the more common virtual devices are listed below:Bonding //bindings, virtual devices bind physical devices so that they are like a single device 802.1Q //ieee standard for establishing a virtual representative of vlanbridging//bridge aliasing interfaces / /a

undisclosed operating mode exists for a usb TV rod Based on the realtek ruijing (also called crab) RTL2832U chip, which can be used as a front-end of a cheap software radio. This important feature is that the chip allows devices to send native I/Q sampling signals to the host, and then the host is responsible for demodulation of the DAB/DVB +/FM signals. This is good news for the GPS software receiver because it covers the target frequency bandwidth.
