Words to know

Pace / speed
Speed = distance per hour (km/h). Pace = time per distance (minutes per km), common in running.
Mbps
Megabits per second: how fast data flows. 25 Mbps is enough for HD streaming. Divide by 8 to get megabytes per second.
Ping / latency / jitter
Ping/latency = how long a tiny message takes to go and come back (ms). Jitter = how much that time jumps around. Lower is better.
Bitrate
How much data a video uses per second. Higher = sharper but bigger file.
SSID / WPA
SSID is your Wi-Fi’s name. WPA2/WPA3 is the password protection used by almost all routers.
