but still robust enough for 10,000 cycles of use. The C-type connector is small enough for modern, slim devices, such as MacBook Air-type notebooks, tablets, and smartphones. It offers three major improvements over 3.0: an 'always right' C-type connector that plugs in without regard to orientation, higher data transfer speeds of up to 10 Gbps (gigabits per second), and the capacity to power any type of device. The newest standard is for USBs is USB 3.1. Over five years later, in 2014, USB 3.1 was released with widespread use expected in 2015. USB3.0 was released in November 2008, almost eight years after the release of USB 2.0. As the number of devices multiplied in quantity and types, the USB port was adopted as the basic connection portal.ĭevices like smartphones, PDAs, tablets, smartphones and video game consoles can connect to computers with USB ports allowing recharging and communication thereby replacing the requirement of adapters and power chargers.

Developed in the 1990s, the Universal Serial Bus (USB) standard was developed to define communication protocols, including cables and connectors, between computers and electronic devices such as printers and scanners.
