USB PowerShare Technology

Universal Serial Bus (USB) is a standard to establish communication between a computer and different devices. USB allows high speed connection of peripherals to a computer. Using USB, you can connect devices like mice, keyboards, printers, external drives, digital cameras, mobile phones, and so on. USB also supports Plug-and-Play installation and hot swapping.

Plug-and-Play allows your computer to recognize that a device is plugged in without restarting your computer. Hot swapping allows you to remove and connect different USB devices without restarting your computer.

USB Connectors
Mini USB — A mini-USB connector is a small cable connector which is used in electronic devices primarily used for data connectivity. Devices such as cameras, MP3 players, mobile phones, and so on use Mini USB connector.

Micro USB — A micro-USB connector is smaller than mini-USB connector and allows you to communicate directly amongst the devices without a need for a computer.

USB Standards
USB 3.0 — Referred to as SuperSpeed USB, USB 3.0 is the latest version of the USB standard. It supports data transmission speed of up to 4.8 gbps, which is ten times faster than its predecessor USB 2.0, yet consumes lesser power.
