Answer to Question 1

A

Answer to Question 2

Popular asynchronous protocols include XModem, YModem, ZModem, and Kermit. In general, asynchronous protocols are simple and relatively inexpensive to implement. However, they are not very efficient. Here is why. An asynchronous protocol requires that every data byte include a start and a stop bit before and after it. This means that each character's byte begins with a start bit and ends with a stop bit. Start bits are always 0, and stop bits are always 1.
