Computer Science A Level. Pg 177 questions 8-10. 8) Asychronous data transmission is where the transmitter and the receiver are not kept in sync. The receiver is only synchronised with the transmitter only at the time of transmission. 9) The start bit signals impending data, and wakes up and sychronies the timer. The stop bit signals the end of the data, and the data can then be manipulated for whatever purposes required. Digital Certificates →. Leave a Reply Cancel reply. Enter your comment here. Create...
