How much stuff
you can send through a connection. Usually measured in bits-per-second.
A full page of English text is about 16,000 bits. A fast
modem can move about 57,000 bits in one second. Full-motion
full-screen video would require roughly 10,000,000 bits-per-second,
depending on compression. Bandwidth is mostly responsible
for how slow or how fast you can access pages on the internet.
