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).

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:

USB-6008

The National Instruments USB-6008 is a low-cost, multifunction data acquisition device (DAQ). It has 8 analog inputs, 2 analog outputs, and 12 digital input/outputs. The digital channels are divided into two ports. When one or more channels on each port is set to either input or output, the port is locked into that particular mode.

The USB-6008 uses the NI-DAQmx driver software and is compatible with LabVIEW, Measurement Studio for Visual Studio, .NET, LabWindows/CVI, and MATLAB (version R2006a and newer).

Cable

An electrical cable is made of two or more wires running side by side and bonded, twisted, or braided together to form a single assembly, the ends of which can be connected to two devices, enabling the transfer of electrical signals from one device to the other. Cables are used for a wide range of purposes, and each must be tailored for that purpose. Cables are used extensively in electronic devices for power and signal circuits. Long-distance communication takes place over undersea cables. Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable. Electrical cables are extensively used in building wiring for lighting, power and control circuits permanently installed in buildings. Since all the circuit conductors required can be installed in a cable at one time, installation labor is saved compared to certain other wiring methods.

The term originally referred to a nautical line of specific length where multiple ropes, each laid clockwise, are then laid together anti-clockwise and shackled to produce a strong thick line, resistant to water absorption, that was used to anchor large ships. In mechanics, cables, otherwise known as wire ropes, are used for lifting, hauling, and towing or conveying force through tension. In electrical engineering cables are used to carry electric currents. An optical cable contains one or more optical fibers in a protective jacket that supports the fibers.

Cable (British band)

Cable were a British indie rock band originally from Derby, UK who released 3 albums in the late '90s: Down-Lift the Up-Trodden ('96), When Animals Attack ('97), and Sub-Lingual ('99), on Infectious Records. The band split up in 1999.

Formed in 1992 by Matt Bagguley and Darius Hinks, Cable were initially inspired by the art-rock leanings of indie-labels such as Touch and Go, Dischord, Blast First, Southern Records and Shimmy Disc, and also UK artists such as Spacemen 3 & My Bloody Valentine. The first settled line-up was Matt Bagguley (vocals/guitar), Darius Hinks (guitar), Pete Darrington (bass), Neil Cooper (drums) and throughout 1993 the band played regularly with underground acts from the U.S (such as Medicine, Polvo, Truman's Water, Rocket From The Crypt..) In early '94 their debut single "Sale of the Century" was released on 7", by Derby-based indie-label Krunch! Records. Radio 1 DJ John Peel played it immediately on his show saying it was the best thing he'd heard that week and phoned the band during the show to invite them to record a session. John Peel remained a loyal fan from that moment on, and altogether the band recorded 4 Peel Sessions.

Cable (comics)

Cable (Nathan Summers) is a fictional character appearing in American comic books published by Marvel Comics, most commonly in association with X-Force and the X-Men. Nathan Summers is the adult son of the X-Man Cyclops (Scott Summers) and Madelyne Pryor (Jean Grey's clone), and the half brother of Rachel Summers, from a possible future timeline, having being transported as an infant to the future, where he grew into a warrior, before returning to the present. The character first appeared as a newborn infant in Uncanny X-Men #201 (Jan. 1986), created by writer Chris Claremont, while Cable's adult identity was created by writer Louise Simonson and artist/co-writer Rob Liefeld, and first appeared in The New Mutants #87 (March 1990).

Publication history

Creation

The character's first appearance was in The New Mutants #86 (Feb. 1990). He does not appear anywhere in the issue's story, but the "next issue" teaser includes a small drawing of the character. This was followed by a full appearance in The New Mutants #87 (March 1990). Though the artist Rob Liefeld is responsible for his visual design, name, and much of his personality, it is claimed that Cable also got some inspiration from editor Bob Harras. Liefeld explains the creation of the character:
