What are the advantages and disadvantages of an asynchronous connection??

Question

What will be an ideal response?

Answer 1

An asynchronous connection has advantages and disadvantages. On the positive side, generation of the start, stop, and parity bits is simple and requires little hardware or software. On the negative side, an asynchronous connection has one disadvantage in particular that cannot be overlooked. Given that seven data bits (ASCII character code set) are often combined with one start bit, one stop bit, and one parity bit, the resulting transmitted character contains three check bits and seven data bits, for a 3:7 ratio. In this scenario of 10 total check and data bits, 3 out of 10-or 30 percent-of the bits are used as check bits. This ratio of check bits to data bits is not very efficient for high amounts of data transfer and, therefore, results in slow data transfers.?
