USB 2.0 connects external drives, gaming controllers, smartphones, MP3 players and other accessories. USB 3.0 transfers data faster than USB 2.0, but only when used with USB 3.0 devices. USB Type-C provides fast speeds and versatile power, featuring connectors with identical ends that plug in upside down or right side up. Adapters allow for video as well as backward compatibility. Thunderbolt provides ultra-high bandwidth for fast data transfer between devices featuring a Thunderbolt or MiniDisplayPort connection. HDMI allows you to connect a projector or display HD media on your HDTV or monitor. Media card slots allow you to transfer photos from your digital camera or camcorder.
