Synchronous bus & Asynchronous bus


Synchronous bus:
  • Transmitter and receivers are synchronized of clock.
  • Data bits are transmitted with synchronization of clock.
  • Character is received at constant Rate.
  • Data transfer takes place in block.
  • Start and stop bit are required to establish communication of each character.
  • Used in high – speed transmission.
Asynchronous bus:
  • Transmitters and receivers are not synchronized by clock.
  • Bit’s of data are transmitted at constant rate.
  • Character may arrive at any rate at receiver.
  • Data transfer is character oriented.
  • Start and stop bits are required to establish communication of each character.
  • Used in low – speed transmission.

    I think the point mentioned regarding start and stop bit under synchronous bus is wrong because synchronous bus uses SYNC bit pattern after a block of data bytes rather than start and stop bits.
