Optimizing Modem Performance: Understanding Communication Parameters

AI Thread Summary
Communication parameters are crucial for modems as they define how data is transmitted over the connection. These parameters include settings like baud rate, control protocols, and IP encapsulation, which must match between the communicating modems for effective data exchange. Modems primarily operate at the physical and data link layers (Layer 1 and Layer 2) of the OSI model, while higher layers are managed by the connected computer. Proper configuration ensures compatibility and optimal performance during dial-up connections.

Why are communication parameters important when a computer uses a modem?

Thank you in advance

If you're talking about the string that you can pass to the modem when dialing, it sets certain preferences for operation, such as the modem's speaker volume and the like.
 
Well you have to tell the modem how to send data to the wire, I take it you are talking about an analoge modem (ISDN Dslam ATM all work differently)...

If you are dialing up to another modem for both modems to communicate they have to speak the same lanagauge, per say... For example the baud rate has to be the same, the control protocol has to be the same the IP encapsulation has to be the same.. Modems only really deal with layer 1 and layer 2 in networking speak layer 3 and above would be handled by your PC... I could go on but Id bore you

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
