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:

Spider-Man 3

Spider-Man 3 is a 2007 American superhero film produced by Marvel Studios, and distributed by Columbia Pictures based on the fictional Marvel Comics character Spider-Man. It was directed by Sam Raimi and scripted by Sam and Ivan Raimi and Alvin Sargent. It is the final film in the Sam Raimi Spider-Man trilogy. The film stars Tobey Maguire, Kirsten Dunst, James Franco, Thomas Haden Church, Topher Grace, Bryce Dallas Howard, Rosemary Harris, J. K. Simmons, James Cromwell and Cliff Robertson in his final film appearance.

Set one year after the events of Spider-Man 2, Peter Parker has become a cultural phenomenon as Spider-Man, while Mary Jane Watson continues her Broadway career. Harry Osborn still seeks vengeance for his father's death, and an escaped Flint Marko falls into a particle accelerator and is transformed into a shape-shifting sand manipulator. An extraterrestrial symbiote crashes to Earth and bonds with Peter, influencing his behavior for the worst.

Development of Spider-Man 3 began immediately after the release of Spider-Man 2 for a 2007 release. During pre-production, Raimi originally wanted another villain to be included along with Sandman, but at the request of producer Avi Arad, the director added Venom and the producers also requested the addition of Gwen Stacy. Principal photography for the film began in January 2006, and took place in Los Angeles and Cleveland, before moving to New York City from May until July 2006. Additional pick-up shots were made after August and the film wrapped in October 2006. During post-production, Sony Pictures Imageworks created 900 visual effects shots.

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).
