1.Analog data is converted to digital so that it is easy to perform mathematical manipulation to the data. So the computers and microprocessors can store, analyse, understand, process, and display the results, since microprocessors deal with digital information.
2. -Isochronous data transfer lies somewhat in between the two other data transmission types. It sends Asynchronous data over a Synchronous transmission system. In such systems each data source is given only a fixed time to transmit its data. In that fixed interval of time, that data source can transfer data at whatever intervals it wants. If it has data which requires less time than the time allotted then it simply wastes the extra time by staying idle.
