What is Bandwidth?
Bandwidth is how much data your internet connection can carry per second — like the width of a pipe. More bandwidth means more data flows at once, so pages load faster and videos stream without buffering. It's usually measured in megabits per second (Mbps).

Frequently asked questions
- Is bandwidth the same as speed?
- Closely related — bandwidth is the maximum capacity; actual speed can be lower due to congestion, distance, or your device.
- What's the difference between bandwidth and latency?
- Bandwidth is how much data flows at once; latency is the delay before it starts arriving. Both shape how fast things feel.
- How much bandwidth do I need?
- Browsing needs little; HD streaming ~5 Mbps, 4K ~25 Mbps, and more if several people share the connection.
