the clocking is mixed with the data in asynchronous transmission
the pulse height is different.
the bandwidth required is different

What I understand that in synchronous transmission clocking in maintained by clock and in the case of asynchronous transmission bit level synchronization is there but no synchronization for byte transfer (or chunk of data).

So there is a concept of start and stop bit to synchronize communication. It means in case of asynchronous transmission synchronization is derived from the data.

In synchronous transmission : the sending and receiving devices are synchronized with a common clock signal. Before the start of the transmission, clocks at both end of devices are synchronized by using sync characters. It uses Bit Synchronous Protocol. It is used for the transmission of a large block of data at relatively higher bit rate.

Asynchronous transmission: is also known as start-stop mode. It is used when data to be transmitted is generated at random intervals of time. Mainly used for the transmission of characters between a keyboard and a computer.
