Answer» hi A reference: http://en.wikipedia.org/wiki/56_kbit/s_modemCorrect. BTW, internal MODEMS are virtually free. Go to your local computer shop.V90 was the internationally agreed 56k modem standard for dialup adopted in the 1990s and V92 was a late 1990s (Aug 1999) enhancement to the V90 standard which used digital techniques to get a higher upload speed, and had various features such as "modem on hold" (supports call waiting by allowing the data session (Internet) to be PUT on hold while a voice call is taken) and "quick dial" The higher upload only worked if both ends of the LINK (i.e. your modem and the ISP's modem) were able to use V92. Since DSL and cable broadband started GETTING popular around that time, not many ISPs invested in upgrading their dialup services to V92 standard. This mean that if you bought a V92 modem it would probably fall back to V90 standard when you used it to connect to most ISPs. You can check if your US Robotics modem can be upgraded to V92 here http://www.usr.com/v92/v-qualify.asp Otherwise, external modems are very cheap. Quote from: soybean on August 11, 2011, 01:03:53 PM this is a hardware-embedded standard. Yes, and this is why we have such a thing as "FIRMWARE". Many US Robotics (and other) V90 modems had (have!) firmware which could be upgraded to support the V92 standard. |
