This video lecture is about the Asynchronous Data Transfer. In most cases, the internal timing in each unit is independent from the other, in that each uses its own private clock for internal registers. Therefore the two units are said to be asynchronous to each other. This approach is widely used in most computer systems.
Two methods can achieve this asynchronous data transfer:
1) Strobe Control
2) Handshaking
The Strobe Control method of asynchronous data transfer employs a single control line to time each transfer. This control line is also known as a strobe, and it may be activated either by source or destination, depending on which initiate the transfer.
Four types of data transfer have been explained:
1) Source Initiated Strobe for Data Transfer
2) Destination Initiated Strobe for Data Transfer
3) Source Initiated Transfer using Handshaking
4) Destination Initiated Transfer using Handshaking

Asynchronous Serial Transfer is explained. A transmitted character can be encounter by receiver from the power of the transmission rules.

An Asynchronous communication interface functions both as a receiver and a transmitter. The interface is boot up for any specific mode of transfer using the control byte that is loaded into the control register. Block Diagram of the Asynchronous Communication Interface along with Truth Table has been discussed in detail.
