Gadget

From Wikipedia, the free encyclopedia

A gadget or gazza is a device that has a useful specific practical purpose and function. Gadgets tend to be more unusual or cleverly designed than normal technology. In some circles the distinction between a gadget and a gizmo is that a gizmo has moving parts, whereas a gadget need not have them. For example, a nifty digital watch would be a gadget, while an analog watch would be a gizmo.

In contrast, a device of clever design that has no practical purpose is called a novelty item.

The etymology of the word gadget is disputed. Some sources say it was "invented" when Gaget, Gauthier & Cie, the company behind the casting of the Statue of Liberty, made a small-scale version of the monument and named it after their firm. Other sources cite a derivation from sailors' terminology; the French gâchette which has been applied to various pieces of a firing mechanism; the French gagée, a small tool or accessory; the French engager, to engage one thing with another; or even a diminutive of the Scottish engineering jargon gadge, a form of measuring device. The spring-clip used to hold the base of a vessel during glass-making is also known as a gadget.

Superheroes, especially ones like Batman and Iron Man whose premise revolves around equipment, have numerous gadgets themselves. There is a cartoon character, Inspector Gadget, whose super powers come from an assortment of gadgets. Also, one of the main characters of the Disney cartoon show Chip 'n Dale Rescue Rangers, Gadget Hackwrench, possess an innate ability to create tools and other technology out of trash and junk.

Occasionally, "gadget" may be used as a placeholder term by an economist discussing a hypothetical situation as the competitor to a widget.

[edit] Types of Gadgets

Recently there appeared rather many gadgets on the market and like many other things that are available in a large amount, gadgets need also a classification. However, gadgets have become something essentially informal, i.e. they are seldom a subject for scientific research, though they might be the result of some scientific experiment.

Since gadget as a term and as an object is rather informal its classification would be also such, although being conducted by logical grounds. For example, the majority of gadgets are based on the principle of portability and ease of usage, such as USB gadgets and additional iPod devices.

This way, one might say that there are following types of gadgets:

USB-based gadgets - such gadgets use the computer's USB port to activate;

Gadgets for iPod - gadgets compatible with Apple's iPod;

Spy gadgets - gadgets as small cameras, pen voice recorders and other small devices for amateur and professional surveillance;

Watch gadgets - multi-functional watches, mostly digital;

Cell phone gadgets - devices to attach to the cell phones;

Health gadgets - devices which follow and control the physiological signs of one's body;

Others - the rest of the gadgets, which are not related to the categories described above.

However, there are such cases when a gadget can have features of two different categories. For example there are watches, which measure the indexes of one's body and display them on the small LCD screen.
