Correct Answer - Option 4 : Baud rate

Baud Rate is defined as the rate of change of signal on transmission medium after encoding and modulation have occurred.

Baud Rate:

  • The baud rate is the rate at which information is transferred to a communication channel.
  • The baud rate indicates the number of electrical oscillations per second that occurs within a data transmission.
  • Baud rate is commonly used when discussing electronics that use serial communication.
  • The higher the band rate, the more bits per second that are transferred.
  • In the serial part content, ‘9600 band’ means that the serial port is capable of transferring a maximum of 9600 bits per second.
  • At baud rates above 76,800, the cable length will need to be reduced.
  • Higher the baud rate, the mere sensitive the able becomes to the quality of installation, due to how much of the wire is untwisted around each device.

​Note:

  • Bit rate is the transmission of the number of bits per second whereas baud rate is the number of signal units transmitted per second.
