baud

A modem displays a baud rate of 9600 on its indicator panel.

Definition

1. Noun:
   • A unit of data transmission speed: In computing and telecommunications, "baud" is a unit that measures the rate at which signal changes or symbols are transmitted per second over a communication channel. Historically, it often corresponded to bits per second, but in modern systems, a single symbol can represent more than one bit.

Usage

• "Baud" is a technical term used primarily in computer science, telecommunications, and electronics to specify the speed of data transfer for devices like modems and serial ports.
• It is typically used with a numerical value (e.g., 9600 baud) and is often part of technical specifications.

Examples

• Noun:
  • The old modem had a maximum speed of 2400 baud.
  • Setting the correct baud rate is essential for the serial communication to work.

Advanced Usage

• "Baud rate": The most common usage, referring specifically to the number of signal changes per second. It is a key parameter in serial communication.
  • You must configure the software to match the baud rate of the hardware device.

Variants and Related Words

• Baud rate (n): The full term for the speed of data transmission, measured in baud.
  • The standard baud rate for this application is 115200.

Synonyms

• Symbol rate: A more precise technical synonym, as baud measures symbols per second.
• Data signaling rate: A broader term for the speed of data transmission.

Notes on Meaning

• Historically, for simple modems, one baud equaled one bit per second (bps). However, with advanced modulation techniques, one symbol (or one baud) can represent multiple bits. Therefore, the bits per second (bps) rate can be higher than the baud rate. For example, a modem with a 2400 baud rate might transmit at 9600 bps if each symbol encodes 4 bits.
