USB 3.0

The Universal Serial Bus, or USB, a popular standard for transferring files to your PC or charging your iPhone, got its first major update in eight years.

USB 3.0 will be 10 times faster than the current USB 2.0 standard, and will increase the amount of electrical current that can be delivered through a USB cable.

Users need the increased speed -- 4.8 gigabits per second, to be precise. And as consumers carry around more devices, charging them off a PC using a USB cable will be much easier than carrying multiple chargers.

With the USB 3.0 specifications nailed down this year, the standard will bump up the power output to 900 milliamps from 100 milliamps, allowing more devices to be charged faster.

At first glance, the USB 3.0 connector looks just like the 2.0 design
