Question

Digital communication advantages include:

RankGuru · Accepted Answer

Digital communication offers several key advantages over analog:
1. **Noise Immunity**: Digital signals represent data as discrete levels (e.g., 0 and 1). Small amounts of noise don't change the level enough to cause an error, unlike analog where noise directly distorts the signal shape.
2. **Error Control**: We can add redundant bits (parity, checksums) to identify and even correct errors that occur during transmission.
3. **Encryption**: Digital data is easier to encrypt for security.
4. **Storage/Processing**: Digital signals can be processed by computers and stored on digital media without loss of quality over time.
