What do upload and download speeds really mean?

Learning the difference between upload and download speeds can help you pick a home internet plan. Let's start with the basics.

What are Mbps?

Mbps stand for Megabits per second. Broadband speeds are measured in Mbps. The higher the number of Mbps, the faster your online activity should be. Bandwidth is the maximum rate at which you can download and upload data from the internet to your computer, whether that be for things like streaming, email attachments, or basic web surfing.
Do what you love, faster

Some things take very few Mbps, such as sending emails without attachments. Some things like video conferencing or streaming live events, need many more Mbps in order to keep up the quality you're looking for.
Know your devices

Once you decide what speeds you'll need to do everything online, you also need to make sure that your device can handle the speeds. If your device can only handle a maximum Mbps rate that's lower than the plan you sign up for, you will only be able to go as fast as your device allows.
