Two quick and easy computer questions

Factual Questions
1

  1. A connector from my mini tower is P+ and P- (the Power LED). On the motherboard, there isn’t any P LED connector, but there is an SDP LED connector. That’s the same thing, right?

  2. The motherboard (I got it off of eBay) has a CNR port and came with a modem for it. Are CNR port modems any better than PCI modems? Or if not, then what’s the difference supposed to be?

Thanks.

  1. I’ve never seen it called an SDP LED. See if you can get the specs for the motherboard from the manufacturer’s web site. That will tell you which is the power LED connector.

  2. CNR is just yet another interface standard designed so that the big guys can produce PC’s a bit cheaper. The design of the modem is far more important in how well it connects than the bus interface. Most modems these days are basically emulated modems, so the computer has to do the job that used to be done by hardware in the old days. However, most computers are so fast and modems are by comparison so slow that you’ll never notice the difference. The main thing is how well the analog side of the modem is designed (the electronics that interface to the phone line). If your phone line is perfect then it won’t matter, but no one has perfect phone lines. Better modems have better noise immunity and such and will connect at higher speeds.

Oops, that should have been SPD. Anyway, I think it’s the power LED.

Oops, in case you couldn’t tell because of my coding mistake, I thanked you for the info in questin #2.
