- 1transmitting datanotes
the direction of data transmission (i.e. in one direction only or in both directions)
the method of transmission (how many bits are sent at the same time)
the method of synchronisation between the two devices. - 2•Asynchronous data transmission refers to data being transmitted in an agreed bit pattern.•Synchronous data transmission is a continuous stream of data. •The data is accompanied by timing signals generated by an internal clock. This ensures that the sender and receiver are synchronised with each other. •The receiver counts how many bits (1s and 0s) were sent and then reassembles them into bytes of data. •The timing must be very accurate here since there are no control bits sent in this type of data transmission.simplex is only one way data transmission
half duplex is in both directions but not at the same time.
full duplex data transmission is in both directions simultaneously - 3—
