Asynchronous transmission includes a start and stop bit with each character transmitted to ensure
A)that the total number of bits is a factor of 10.
B)to allow a continuous stream of data.
C)to prevent single bit errors from occurring.
D)to allow the receiver to maintain synchronization with the sender.
E)to allow variable length encoding schemes.

Question

Quizplus · Accepted Answer

The start and stop bits in asynchronous transmission are used to signal the beginning and end of a character, which helps the receiver maintain synchronization with the sender. This is particularly important because there is no continuous stream of data in asynchronous transmission, unlike synchronous transmission. Option A, B and E are incorrect because the start and stop bits are not related to the total number of bits, continuity of data, or variable length encoding schemes. Option C is partially correct because start and stop bits do detect errors in transmission, but their main purpose is synchronization.
