But because two different and incompatible technologies, K56flex and x2, were initially introduced and the true speeds of 56K modems are not always what they are advertised to be speed-hungry Internet users were left with many questions. We hope to answer most of them here.
Speed is the primary benefit.
Theoretically, you can access the Internet at twice the speed of your old 28.8K modem. And using ISDN or similar data-transmission speeds is more costly. Other high-speed technologies such as ISDN and xDSL simply aren't available in many places. Though all v.90 modems are 56K modems, not all 56K modems are v.90 modems. A v.90 modem is a 56K modem based on international standards.
