Key: 1 Byte = 8 bits. To convert Mbps to MBps, divide by 8.
To calculate download time: divide file size by bandwidth speed. Remember to convert units: 1 byte = 8 bits, so Mbps (megabits) / 8 = MB/s (megabytes). Formula: Time (seconds) = File Size (MB) / (Speed Mbps / 8). A 1GB file at 100 Mbps: 1000 MB / 12.5 MB/s = 80 seconds. Real speeds are typically 80-90% of advertised due to overhead.
Mbps (megabits per second) measures network speed. MBps (megabytes per second) measures data transfer. 1 byte = 8 bits, so 100 Mbps = 12.5 MBps. ISPs advertise in Mbps; file downloads often show MBps.
Reasons include: protocol overhead (~10-15%), network congestion, distance from server, Wi-Fi interference, old router/modem, ISP throttling, and server limitations. Typical real-world speeds are 50-80% of advertised.
SD video: 3-4 Mbps. HD (1080p): 5-8 Mbps. 4K: 25+ Mbps. Video calls: 2-4 Mbps. Online gaming: 3-6 Mbps (low latency matters more). Multiple users multiply requirements.
Latency (ping) is the delay before data transfer starts, measured in milliseconds. It affects responsiveness but not bulk download speed. Low latency (<50ms) matters for gaming and video calls, not large file downloads.
Bits to bytes: divide by 8. Kilo (K) = 1,000 (or 1,024 for binary). Mega (M) = 1,000,000. Giga (G) = 1,000,000,000. Network uses decimal (1 KB = 1000 B), storage uses binary (1 KB = 1024 B).
