What is bandwidth?
Bandwidth is the amount of data that can be transferred over a network connection in a given time. It is often shown as Mbps or Gbps.
What is latency?
Latency is the delay between sending data and receiving a response. It is usually measured in milliseconds.
Simple analogy
Bandwidth is like the width of a road. Latency is like the travel time. A wide road can carry many cars, but the trip can still take time if the destination is far away.
Why this matters
Video calls, remote desktop, cloud apps, online games, and VoIP need low latency. Large downloads need enough bandwidth.
Troubleshooting tip
If speed test results look good but apps feel slow, check latency, packet loss, Wi-Fi signal, DNS, VPN, and server location.
