1. Asynchronous transmission is a method of transferring data that has control signals embedded in it in order to synchronise the transmission.
2. In Asynchronous transmission the transmitter's and receiver's clocks are kept synchronised right from the start and only become out of sync during transmission.
3. Start and stop bits are used as ____________ to indicate where the message starts and where it ends.
4. Before a message is sent, a _____________________ is added to the message.
5. Start and stop bits are essentially used to _____________________________________________
6. It is not necessary for both devices to send and receive signals at the same rate, as being out of sync in asynchronous transmission is the norm.
7. An example would be that the bit string: 00101111001 would have the stop bit 0 and a start bit of 1 added to it giving: 0 00101111001 1
8. Start bit synchronises receiver (clock) (to transmitter/data). It also locks receiver and transmitter in phase and starts receiver's clock or _________________
9. Stop bit allows start bit to be recognised and it allows the receiver to ____________________
10. In Asynchronous transmission the sender and receiver are only synchronized when data is being sent
