Thunderbolt

Thunderbolt is an input/output (I/O) interface for connecting peripheral devices to a computer, supporting high-resolution displays and high-performance data devices through a single, compact port.

Thunderbolt combines PCI Express and DisplayPort into a serial data interface that can be carried over a single cable.

With PCI Express technology, you can use existing USB and FireWire peripherals - even connect to Gigabit Ethernet and Fiber Channel networks - using simple adapters.

Thunderbolt uses a Mini DisplayPort connector and DisplayPort 1.1a protocol, supporting a top speed of 10 Gbps*.

Because Thunderbolt I/O is based on DisplayPort technology, any Mini DisplayPort display plugs right into the Thunderbolt port. Thunderbolt also supports DisplayPort, DVI, HDMI, and VGA displays through the use of adapters.

Thunderbolt was developed by Intel and brought to market with technical collaboration from Apple. It was introduced commercially on Apple's updated MacBook Pro lineup in February 2011, using the same connector as Mini DisplayPort.

* Thunderbolt features two data channels, each supporting 10 Gbps, hence a total 20 Gbps is achievable.
