A gadget is a small technological object (such as a device, application, program or an appliance) that has a particular function, but is often thought of as a novelty. Gadgets are invariably considered to be more unusually or cleverly designed than normal technological objects at the time of their invention. Gadgets are sometimes also referred to as gizmos.
Gadgets can be hardware or software. I will point towards some websites related to this technology.
Gadgets powered by Google are miniature objects made by Google users like you that offer cool and dynamic content that can be placed on any page on the web. Gadgets might come in handy when you’re at work (to-do list, currency converter, calendar), at school (calculator, Wikipedia, translation tool), or just passing time (news, blogs, games). You can add gadgets you like to iGoogle and, if you have Google Desktop installed, you can also add gadgets to your computer’s desktop.
