In terms of speed, a fiber-optic connection is usually two tothree times faster than cable or DSL. It's so fast, in fact, thatits speed is measured in megabits rather than bits.The fastest internet service is to buy a dedicated T1 line,which costs around 250$ per month. Of the available services thebest depend completely upon the implementation rather than thetype. Cable is theoretically fastest, but is hardly ever providedat the speed possible.
