Question

A method of asynchronous data transfer that employs two control lines to ensure successful data transfer?

Answer 1

*Answer*

Handshaking provides a mechanism for addressing this issue. Handshaking usually uses two additional hardware lines, one is called “strobe” and the other is called “acknowledge”. The sender provides the signal to the strobe line and the receiver provides the signal to the acknowledge line.

Handshaking can be used in both parallel data transfer and serial data transfer.
