The broadband like it’s predecessors, information travels in two directions. Downstream and Upstream.
Downstream refers to information going from the Internet to your computer, like when a new web page is loaded.
Upstream refers to information from your computer to the Internet, like the click of the mouse- that tells a web page where you'd like to go next.
Firstly, Internet transfer speeds are measured in kilobits per second and megabits per second, don’t mistake it for kilobytes and megabytes, we use these terms when we talk about hard disks and files.
