What Is Network Bandwidth?

Network bandwidth is the amount of data that can be transmitted across a network in a given time, usually measured in bits per second (bps).

Key Units Explained

  • Kbps: Kilobits per second (1,000 bps)
  • Mbps: Megabits per second (1,000,000 bps)
  • Gbps: Gigabits per second (1,000,000,000 bps)

Bits vs. Bytes

  • 1 Byte = 8 bits
  • 100 Mbps = 12.5 MBps (megabytes per second)

Transfer-Time Formula

Transfer Time (s) = File Size (bits) ÷ Bandwidth (bps)

Real-World Example

Transferring a 1 GB file over a 100 Mbps network: 1 GB = 8,000 Mbit → 8,000 ÷ 100 = 80 s

Practical Guide

Video Streaming
  • • 4K streaming: at least 25 Mbps
  • • 8K streaming: at least 100 Mbps
Cloud Backup
  • • 50 Mbps: about 4 h 27 min
  • • 100 Mbps: about 2 h 13 min
  • • 1 Gbps: about 13 min 20 s
Game Updates
  • • 100 Mbps: about 1 h 7 min
  • • 1 Gbps: about 6 min 40 s

Frequently Asked Questions

Network congestion, router performance, and server response all affect actual speed.

Mbps means megabits per second; MBps means megabytes per second. 1 MBps = 8 Mbps.

Distance, obstacles, simultaneous users, and wireless interference can slow Wi-Fi.
