A network engineer is configuring a point-to-point WAN connection between two branch offices using a serial interface. The link operates at 2.048 Mbps. The engineer needs to calculate the data rate in kilobits per second (kbps) for this connection. What is the correct data rate?
- A204800 kbps
- B20480 kbps
- C2048 kbps
- D204.8 kbps
Show answer & explanationAnswer & explanation
Correct answer: C. 2048 kbps
To convert Megabits per second (Mbps) to Kilobits per second (kbps), multiply by 1000. So, 2.048 Mbps * 1000 = 2048 kbps.
Why the other options are wrong
- A. Incorrect. This would be 204.8 Mbps.
- B. Incorrect. This would be 20.48 Mbps.
- D. Incorrect. This would be 0.2048 Mbps.
Data Rate Conversion (Mbps to kbps)
The process of converting data transfer speeds from Megabits per second (Mbps) to Kilobits per second (kbps) or vice-versa.
- 1 Mbps = 1000 kbps (in networking context, not always 1024).
- 1 kbps = 1000 bits per second (bps).
- This conversion is fundamental for understanding network bandwidth.
