USB 3.0

USB 3.0 (renamed to USB 3.1 Gen 1 in 2015) is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer mode SuperSpeed (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times faster than the USB 2.0 standard. USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs, and the initials SS.

A successor standard, USB 3.1 (renamed to USB 3.1 Gen 2 in 2015), was released in July 2013 with the new transfer mode SuperSpeed+ that can transfer data at up to 10 Gbit/s (1.25 GB/s, twice the rate of USB 3.0), bringing its theoretical maximum speed on par with the first version of the Thunderbolt interface.

Overview

The USB 3.0 specification is similar to USB 2.0 but with many improvements and an alternative implementation. Earlier USB concepts like endpoints and four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB 3.0 traffic. The changes in this specification make improvements in the following areas:

World of Tanks

World of Tanks is a massively multiplayer online game developed by Belarusian-Cypriot company Wargaming, featuring early to mid-20th century era fighting vehicles. It is built upon a freemium business model where the game is free-to-play, but participants also have the option of paying a fee for use of "premium" features. The focus is on player vs. player gameplay with each player controlling an armored vehicle, which may be a light, medium or heavy tank, tank destroyer, or self-propelled gun. World of Tanks debuted as an eSports game at the World Cyber Games 2012.

On 10 June 2013 it was announced that World of Tanks was coming to Xbox Live Arcade on 12 February 2014 as World of Tanks: Xbox 360 Edition. Xbox 360 players use separate servers to those playing the Windows version, and players of each version have separate accounts. The Xbox 360 version was developed by Wargaming West studio. An Xbox One version has been announced, and was released on 28 July 2015. A PlayStation 4 version is scheduled to release in 2016.World of Tanks has also recently expanded to mobile platforms under the name World of Tanks Blitz, in addition to a board game titled World of Tanks Rush and a collectable card game titled World of Tanks: Generals.

USB

USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum.

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.

Overview

In general, there are three basic kinds or sizes related to the USB connectors and types of established connection: the older "standard" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on USB flash drives), the "mini" size (primarily for the B connector end, such as on many cameras), and the "micro" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on most modern mobile phones).
