ESD and ECP Questions
Question #1
My book says that as little as 80 volts can harm an IC.
All the practice tests I've seen say it should be 30 volts.
Question #2
My book says that a human can not feel a static transfer less than 3000 volts.
The practice tests seem to vary on the correct answer. Some have been as low as 200 volts.
Question #3
It is my understanding that the IEEE 1284 ECP (enhanced capabilities port) is Bi-directional, can use DMA, can use data compression, and was developed to speed up printing. Can this cable be used for a laplink cable and any other bi-directional process that needs to be performed?
What would be the correct answers as far as Comptia is concerned.
I am consistently scoring high 90's to 100% on all the practice tests but it is unsettling that these free practice tests vary in there answers. You would think if someone took the time to put them on the internet they would take the time to proof the answers. I take the hardware test tommorrow so wish me luck.
Also, could anyone suggest other websites besides this one (which is the best i have found) with good practice tests. Thanks for your help.

I'm not 100% sure about the ECP question either, but my guess would be: Yes, depending on the cable...

Good luck on your exam tomorrow!

i have found that some sites seem to ask questions on things not covered by the objectives, or ask about topics in greater depth than necessary. examnotes and cert21 are guilty of this, but at the same time, knowing things in greater depth isn't a bad thing either
