Describe about Asynchronous Transmission

• It uses the start and stop bits for signifying the beginning bit of ASCII character that is to be transmitted.For instance, ‘0100 0001 would become ‘1 0100 0001 000 1 0’’.

• The additional one bit at the beginning and ending of the transmission refers the receiver that a character is entering and the character is ended.

• When data need to be sent intermittently, this method is used.

• The start and stop bits are supposed to be opposite polarity.

• By this process, the receiver recognizes the second packet of the information that is being sent.
