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).

Gaienhofen
Gaienhofen is a town in the district of Konstanz in Baden-Württemberg in Germany.
Since 1974, Gaienhofen consists of four villages: Gaienhofen, Gundholzen, Hemmenhofen and Horn. Attractions, apart from the Lake of Constance, include the Hermann-Hesse-Höri-Museum and Otto-Dix-Haus.
World heritage site
It is home to one or more prehistoric pile-dwelling (or stilt house) settlements that are part of the Prehistoric Pile dwellings around the Alps UNESCO World Heritage Site.
Twin towns
Gaienhofen is twinned with:

Horn (anatomy)
A horn is a pointed projection on the head of various animals consisting of a covering of keratin and other proteins surrounding a core of live bone. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae (pronghorn) and Bovidae (cattle, goats, antelope etc.).
One pair of horns is usual; however, two or more pairs occur in a few wild species and domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro.
Horns usually have a curved or spiral shape, often with ridges or fluting. In many species only males have horns. Horns start to grow soon after birth, and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core). Partial or deformed horns in livestock are called scurs. Similar growths on other parts of the body are not usually called horns, but spurs, claws or hoofs depending on the part of the body on which they occur.
Horn, Germany
Horn is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Rhein-Hunsrück-Kreis (district) in Rhineland-Palatinate, Germany. It belongs to the Verbandsgemeinde of Simmern, whose seat is in the like-named town.
Geography
Location
The municipality lies in the Hunsrück roughly 7 km eastsoutheast of Kastellaun and 6 km north of Simmern.
History
Bearing witness to early human habitation in the Horn area are Roman and Neolithic archaeological finds. There is also a mediaeval motte-and-bailey castle.
In the 12th century, Horn had its first documentary mention in connection with the noble family that bore the same name, but it seems that the actual “first mention” in 1135 is a falsified document. Nevertheless, a genuine document from 1166 has the same contents and names the same persons, thus confirming the 12th century, at least, as the earliest time when the village is known to have existed.
Together with Laubach and Bubach, Horn belonged at this time to the Imperially Immediate Estate (Reichsgut). Landholdings seem to have been held by a noble family von Horn. It could be that this family’s noble seat was at the castle, the Horner Burg. The complex’s remnants can be found west of the village. In shape it was a special form of motte-and-bailey. In 1567, Johann von Koppenstein sold Meinhard von Schöneberg the remnants.
