Notebook and laptop computers have these traits: 1) Small: Usually about one foot (30 cm) wide and less than two inches (5 cm) thick. They can fit on a lap. 2) Lightweight: Usually less than 8 pounds for notebooks, and less than 12 pounds for laptops. 3) Portable due to 1) and 2) and being battery-powered. 4) They use an integral, hinged (folding), thin, flat panel display; usually a liquid crystal display: LCD.

Quiet computers are those that make little or no normal operating noise, incidentally or by design. Most desktop computers emit a constant whir, and sometimes roar of noise, from fans as they spin, disk drives (hard, CD/DVD) as they spin and read and store data, and from electrical transformers as they hum and whine. Sound is also emitted by speakers, but this is intentional, and usually considered desirable by users, if not by coworkers. Many users find computer noises distracting, even irritating, more so as they increasingly listen to music and videos on computers, and use IP telephony. Ergonomic (human factors) research in noise pollution, usually in the workplace, shows that noise harms user concentration and productivity, more so where many computers operate in confined spaces, more so where no effort is made to improve acoustics. The market for quieter computers is growing worldwide, more in Europe.

This category covers set-top boxes as well as related boxes and devices that are somehow connected to a TV. The electronic box which sits on top of your TV set connects your incoming cable TV, satellite dish, broadband, internet or other transmission signal to your TV set. Set-tops vary greatly in their complexity with older models merely translating the frequency received off cable into a frequency suitable for the television set while newer models can be addressable with a unique identity much like a telephone and are also evolving into residential entertainment "gateway" boxes which may include advanced interactive on-demand capabilities such as video-on-demand, personal video recording, enhanced television link interaction, interactive program guide TV listings, and internet capabilities.
