Explain synchronous communication and asynchronous communication.

Photo of author

By Dipali Umre

Synchronous Communication:

  1. In synchronous communication, data is sent in a continuous stream without pauses between characters.
  2. Special sync patterns are used to indicate the beginning and separation of data blocks.
  3. It operates at a fixed speed, with a constant flow of data bits.
  4. It’s commonly used when two devices, like computers, are directly communicating or when a terminal is connected to a computer with a buffer.

Asynchronous Communication:

  1. In asynchronous communication, each character is framed by start and stop bits.
  2. There are gaps between characters to separate them.
  3. Bits within a character frame, including start, parity, and stop bits, are sent at a specific baud rate.
  4. It’s preferred for slower speed peripherals communicating with a computer.
