baud rate
Definition
Noun: - A measurement of data transmission speed: Specifically, the number of signal changes or symbols transmitted per second over a communication channel. In early digital communications, one baud often corresponded to one bit per second, but this is not always the case with modern modulation techniques.
Usage
The term is used primarily in computing and telecommunications to specify the speed of data transfer for devices like modems, serial ports, and other communication interfaces. - The old modem had a maximum baud rate of 9600. - You need to configure the correct baud rate for the serial connection to work.
Advanced Usage
- Technical Context: In precise technical terms, "baud rate" (or simply "baud") measures the symbol rate. A symbol can represent more than one bit (e.g., in QAM modulation), meaning the bit rate (in bits per second) can be higher than the baud rate.
- Although the baud rate is 2400, the bit rate is 9600 bps due to advanced encoding.
Variants and Related Words
- Baud (n): Often used synonymously with "baud rate," though technically "baud" is the unit (symbols per second).
- The connection speed is 115200 baud.
- Bit rate (n): The number of bits transmitted per second, which is related to but distinct from baud rate.
- A higher bit rate allows for faster file transfers.
Synonyms
- Symbol rate: A more precise technical synonym.
- Data signaling rate: A broader term that can be similar in context.
Related Phrases
- Set the baud rate: A common instructional phrase for configuring communication devices.
- Make sure to set the baud rate on both devices to the same value.
Noun
-
(computer science) a data transmission rate (bits/second) for modems
