(n.) A rechargeable battery used in portable computer devices, such as notebook computers. The most common substances used in computer battery packs are nickel cadmium (Nicad), nickel metal hydride (NiMH), and Lithium Ion.
A new type of battery, called a smart battery, provides the computer with information about its power status so that the computer can conserve power intelligently. With a normal battery, the computer makes estimates about the battery’s condition that are not always correct.
Pronounced bawd, the number of signaling elements that occur each second. The term is named after J.M.E. Baudot, the inventor of the Baudot telegraph code. At slow speeds, only one bit of information (signaling element) is encoded in each electrical change. The baud, therefore, indicates the number of bits per second that are transmitted. For […]
Short for drive bay, this refers to a site in a personal computer where a hard or floppy disk drive, CD-ROM drive or tape drive can be installed. Thus, the number of drive bays in a computer determines how many mass storage devices can be internally installed. For PCs, bays come in two basic sizes: […]
- a Beacon
Beacons are small, often inexpensive devices that enable more accurate location within a narrow range than GPS, cell tower triangulation and Wi-Fi proximity. Beacons transmit small amounts of data via Bluetooth Low Energy (BLE) up to 50 meters, and as a result are often used for indoor location technology, although beacons can be used outside […]
To transmit information to another device wirelessly using the infrared port built into Palm and other devices.
In aeroacoustics, beamforming is a signal processing technology that is used to direct the reception or transmission (the signal energy) on a transducer array in a chosen angular direction. Beamforming concentrates the array to sounds coming from only one particular direction to listen to sounds in one direction and ignore sounds in other directions. Beamforming […]
