Latency is the amount of time it takes for data to travel from your device to a server and back again. While bandwidth determines how much data can move at once, latency determines how quickly each request and response happens.
What Is Latency?
Latency is measured in milliseconds (ms). Lower latency means faster response times. High latency creates delays that you can feel, especially in real‑time applications.
Latency is often called “ping,” especially in gaming, but both terms refer to the same idea: how long it takes for data to make a round trip.
What Causes Latency?
Several factors influence latency:
- Distance: Data travelling across Canada or internationally takes longer.
- Routing: Packets may take indirect paths depending on network conditions.
- Congestion: Busy networks slow down response times.
- Wi‑Fi interference: Wireless signals add extra delay.
- Server load: A busy server responds more slowly.
Why Latency Matters
Latency affects activities that require quick, real‑time communication. For example:
- Online gaming: High latency causes lag and delayed actions.
- Video calls: High latency creates awkward pauses or talking over each other.
- Web browsing: Pages may feel slow to start loading.
- Remote work tools: Cloud apps respond more slowly.
Latency vs. Bandwidth
Latency and bandwidth are different but related:
- Bandwidth = how much data can move at once
- Latency = how quickly each request happens
You can have high bandwidth but still experience delays if latency is high.
How to Reduce Latency
Some ways to improve latency include:
- Using Ethernet instead of Wi‑Fi
- Moving closer to your router
- Reducing the number of active devices
- Restarting your router to refresh routing tables
- Choosing servers closer to your location
Summary
Latency is the delay between sending and receiving data. Lower latency means smoother gaming, clearer video calls, and faster‑feeling browsing. It’s one of the key factors that shapes your overall internet experience.
