Network Bandwidth
Definition
Network bandwidth describes the possible amount of data per unit of time.
The maximum amount of data that a network path can transmit under specified conditions per unit of time; the actual achieved throughput can be significantly lower.
Simply explained
Like the width of a road, it limits how much data can pass through simultaneously.
Why it matters in practice
Helps develop and operate digital systems robustly, securely, and maintainably.
Example from business
A model service transmits large embeddings and hits the network limit despite low CPU load.
Limits and pitfalls
- Confusing nominal bandwidth with actual throughput or ignoring latency, overhead, and competing traffic.
Origin & history
Bandwidth is a fundamental metric of communication networks and should be distinguished from latency and throughput.
Use in mid-sized companies
- Possible example: A model service transmits large embeddings and hits the network limit despite low CPU load.
