The service level of your ISP account is normally based on the promised download speed when you first signed up, usually expressed in megabits per second (Mbps). A speed test verifies your download speed as well as other related data, including upload speed and network latency.
Download Speed: Download speed denotes how quickly Internet content is transferred to your computer or home network in Mbps.
Upload Speed: Upload speed is naturally the opposite of download speed, describing how quickly you are able to upload content to the Internet. This is important if you use your Internet to regularly share personal videos, music, and images.
Ping (Latency): Ping reflects the amount of latency in a computer network, denoting the amount of time it takes data to travel from one computer to another on the network. It is normally expressed in milliseconds. We try to find the closest test server to your location.
