Speed & Performance

Bandwidth

The maximum amount of data that can be transmitted over an internet connection in a given time, often used interchangeably with "speed" but technically refers to capacity rather than rate.

What It Means

Bandwidth is like the width of a highway — more lanes (higher bandwidth) means more cars (data) can travel simultaneously. A 1 Gbps connection has the bandwidth to stream 40 simultaneous 4K video streams, but a single stream will not load faster than on a 100 Mbps connection. The distinction matters for households with many connected devices. A family of four with smart TVs, laptops, phones, and smart home devices may need 200-500 Mbps of bandwidth even if no single device uses more than 50 Mbps.

Download Speed
The rate at which data travels from the internet to your device, measured in megabits per second (Mbps). Determines how fast web pages load, videos stream, and files download.
Upload Speed
The rate at which data travels from your device to the internet, measured in Mbps. Critical for video calls, cloud backups, live streaming, and working from home.
Latency (Ping)
The time it takes for a data packet to travel from your device to a server and back, measured in milliseconds (ms). Lower latency means more responsive connections.
Mbps (Megabits Per Second)
The standard unit for measuring internet speed. One megabit equals one million bits of data. Not to be confused with megabytes (MB), which are eight times larger.
