This document outlines the key differences between data communication and voice communication.
Key Differences
The following table summarizes the main distinctions:
| Feature | Data Communication | Voice Communication |
|---|---|---|
| Connection Setup Time | Requires connection setup time of about 1 second or less. | Requires connection setup time of about 1 second to 1 minute. |
| Communication Type | One or two-way communication based on application (e.g., FTP, browsing, VOIP). | Mostly two-way communication. |
| Error Handling | Data received is typically error-free. In case of errors, either retransmission is initiated or error correction techniques (FEC) are used. | Voice received often contains noise and degradation in quality. |
| Transmission Pattern | Transmission is usually in the form of bursts. | Transmission is continuous due to the real-time nature of voice. |
| Transmission Delay Sensitivity | Data can be stored and transmitted based on congestion and application (SMS, email). Tolerant to some transmission delays. | Not tolerant of transmission delays and hence needs to be transmitted in real-time. |
| Connection Duration | Connection may be required for 24 hours/day and 7 days/week in certain applications, such as ATM cash machines. | Connection duration is typically limited to several minutes. |
| Bandwidth Requirements | May require a wide range of bandwidths. | May require a fixed bandwidth of about 4KHz. |
