A file that contains a sequence, or batch, of commands. Batch files are useful for storing sets of commands that are always executed together because you can simply enter the name of the batch file instead of entering each command individually.
In DOS systems, batch files end with a.BAT extension. For example, the following DOS batch file prints the date and time and sets the prompt to GO>:
Whenever you boot a DOS -based computer, the system automatically executes the batch file named AUTOEXEC.BAT, if it exists.
Many operating systems use the terms command file or shell script in place of batch file.

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 […]
