Describe Synchronous Transmission. - Synchronous transmission does not use start and stop bits, hence data transfer rate is quicker. - The transmission is synchronized by speeding up at both the sending and receiving ends. - This uses clock signals that are built at each component. - Continual stream of data is sent between two nodes. - Re-synchronization is one of the methods to address the lost bits. - This method uses check digits instead of parity bits for ensuring the byte is correctly being interpreted and received. 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. - Th...
