Digital data is easy to store and retreive. Perfect copies can be made as everything is reduced to only 2 states, on and off, or 1 and zero.
By using methematics, error correction can be applied. So if mistakes are made by the transmission method, the correct digit can be calculated and re-inserted.
A digital system can recognize digital data i.e. data only in form of 0 & 1, if data is not in digital form we have to convert it using analog to digital converters.
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
Yes, it is.
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
The full form of CDS is the Compact Disc - Read-Only Memory or Compact Disc - Digital Audio. It is a digital optical disc data storage format.

Binary data refers to data that is represented using only two possible values, typically 0 and 1. This is the fundamental language of computers, where everything is ultimately represented in binary form. On the other hand, digital data is a broader term that encompasses any data that is stored or transmitted in discrete, non-continuous values. While binary data is a specific type of digital data, digital data can also include other numeral systems like decimal or hexadecimal.
