QUESTION How much is your internet speed affected by how you are using it?

RESEARCH I found that some people need faster internet because of the way they use it. If you do a lot of things on the internet, you will need a faster speed, so you can do multiple things at once without being slowed down. A lot of things use the home internet connection. One of them is the phone. The VOIP phone uses the internet to make phone calls instead of telephone wires. A Microcell uses the internet to route cell phone traffic so you can get a better signal at home. Any streaming video service plays movies over the internet. If you want to be able to watch a Netflix movie without buffering, you should get a faster speed. The quality of your online experience is affected by your internet speed. If you want to watch a show in HD, you should get a faster speed, so you can watch more. Also, videos will buffer less if you have a faster speed. The voice quality will be better if you have a faster connection.

CONCLUSION My IV was the devices using the internet. The DV was the internet speed. The controls were: same computer, same speedtest server, same connection. My data shows that the more devices using the internet, the less available bandwidth.

APPLICATIONS AND FURTHER EXPLORATIONS • When your internet speed is slow and you want to determine the cause • Diagnosing Issues with your connection • It would be useful to test the speed in a variety of conditions
