Frequently Asked Questions
Common questions about bandwidth calculations
What's the difference between Mbps and MB/s?
Mbps (megabits per second) measures bandwidth, while MB/s (megabytes per second) measures transfer rate. 1 byte = 8 bits, so 100 Mbps = 12.5 MB/s.
Why is network efficiency important?
Real networks have overhead from protocols, congestion, and other factors. Typical efficiency ranges from 60-90% of theoretical maximum, so it's important to account for this in planning.
How accurate are the calculations?
The calculations are mathematically accurate for the given inputs. However, real-world performance can vary due to network conditions, hardware limitations, and other factors.
What factors affect transfer speed?
Transfer speed is affected by bandwidth, latency, packet loss, network congestion, hardware performance, protocol overhead, and the number of concurrent transfers.
Can I calculate for multiple files?
Yes, simply multiply the single file size by the number of files to get the total size, then use that for your calculations. The results will show total transfer time.
