Understanding Your Results
There are a number of factors that affect the speed of your connection to the Internet. One of the primary factors is the type of connection you have. Below is a list of connection types and typical connection speeds.
Other factors include your computer's age and operating system, security software installed on your computer and on the hardware between you and the site you are accessing, how many people share your internet access (both within your household and within the link between your neighborhood and your provider) and the quality of the internet link between your provider and the site you are accessing.
For most providers, the advertised speed is the maximum speed between the access hardware in your home, e.g. cable modem, and your provider's Internet portal. That is the part your provider has control over. However, once your connection leaves your provider's control, your connection is limited to the weakest link. For example, if the web site you are connecting to is at the end of a very busy slower DSL connection, you are limited to the DSL connection's speed.
The speed test on this site is measuring the ability of your computer to receive (download speed) and send (upload speed) to the Internet. The test measures transmission rates in megabits (millions of bits) per second (Mbps). One megabit equals 1,000,000 bits of information. Data transmission rates are often presented in Mbps or kbps (kilobits per second, 1000 bits). However, files sizes are often stated in megabytes. One byte is equal to 8 bits, therefore 1,000,000 bits (1 Mbps) a second is equivalent to 125,000 bytes per second. To download a 1 megabyte (1 MB) file at 1 Mbps would take 8 seconds. A 30 second video clip is typically about 10 MB so it would take 80 seconds to download at 1 Mbps. There are many factors that can affect the speed test. To get a reliable indication of your actual connection speed it is best to take the test several times at different times during the day.
The National Telecommunications and Information Administration (NTIA) defines a connection as broadband if it can achieve at least 768 Kbps download speeds and 200 Kbps upload.
Connection Type Values
