| T-1 |
A leased-line connection capable of carrying data at 1,544,000
bits-per-second. At maximum theoretical capacity, a T-1 line could move a
megabyte in less than 10 seconds. That is still not fast enough for
full-screen, full-motion video, for which you need at least 10,000,000
bits-per-second. T-1 is the fastest speed commonly used to connect networks to
the Internet. |
| T-3 |
A leased-line connection capable of carrying data at 44,736,000
bits-per-second. This is more than enough to do full-screen, full-motion video.
