IA meaning in Computer Hardware ?

An Internet appliance is a consumer device whose main function is easy access to Internet services such as WWW or e-mail. The term was popularized in the 1990s, when it somewhat overlapped in meaning with an information appliance, Internet computer, network computer, or even thin client, but now it has fallen out of general use.

Internet appliance was contrasted with any general purpose computer. The basic design idea behind Internet appliance is that it can be made cheaper and much more usable by narrowing its functionality and limiting available configuration options. Modern smart phones and tablet computers do approximately the same things, but are more powerful, more successful in the market, and generally not classified as Internet appliances.
