| Bandwidth | 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 15,000 bits in one second. Full-motion full screen video would require roughly 10,000,000 bits-per-second, depending on compression. |
| Baud | In common usage the baud rate of a modem is how many bits it can send or receive per second. Technically, baud is the number of times per second that the carrieer signal shifts value, for example a 1200 bit per second modem actually runs at 300 baud, but it moves 4 bits per baud (4 × 300 = 1200 bits per second). |
