1. Why we need to change the analog signal to digital?
2. Why isochronous is better than synchronous ?
1.ans:Analog to Digital Conversion
An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by minimizing errors.2.ans: isochrnous is better than synchronous becuse In Synchronous transmission, Data is sent in form of blocks or frames. In isoynchronous transmission, Data is sent in form of byte or character. ... In Synchronous transmission, time interval of transmission is constant. In isoynchronous transmission, time interval of transmission is not constant, it is random.
1. All the data we get in nature is analog type whether it's voice, nature signals, or others. But most of the processing is performed in a digital signal, so we need to change/convert the analog signal to digital.
2. Isochronous is better than synchronous because the isochronous transmission confirms that, the data arrive at a fixed rate, unlike synchronous transmission.

1.An analog of the Digital Converter (ADC), converts any analog signal into quantitative data, which simplifies processing and reduces errors and makes it more accurate and reliable.
2.Isocronus is better than synchronous because isocronus transmission ensures that the data reaches a certain rate as opposed to synchronous transmission.

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. Otherwise if it has data which requires more time to transmit than given then it sends the remaining data in its next turn. These systems do not have error check mechanism because it is not possible to re-transmit the data after an error due to strict timing conditions.

1. Ans. Any physical signal, such as a sound, or a light, or a voltage, is considered an analog signal. The thing about analog signals is that they are infinite in nature.
There are infinite numbers of sounds we can hear, there are infinite colors to perceive, and there are infinite numbers between the 1 and 2.
Digital on the other hand deals with discrete or finite signals or finite. There is only a ‘2’ between 1 and 3; no infinity.
As we can imagine, dealing with analog signals is very difficult. They are difficult to store and even more difficult to process. This is where analog to digital converters come into play.
2. Ans: Advantages of isochronous transmission-
(i)Transmission speed is much higher.
(ii)There is no need to pause between each character.
(iii)Start bit at the beginning of each character and Stop bit at the end is not required.
Disadvantages of synchronous transmission-
(i)Primary storage device is required.
(ii)Comparatively expensive.
(iii)Synchronisation between the source and target is required.
So, isochronous is better than synchronous.
