Again a very straightforward doubt here. While going through my notes I figured I have written that Universal Serial Bus can allow connecting up to 127 devices and Firewire up to 63. I don't get this. How can one do that and also why would someone do that??
Also, I noticed Wes Sir had emphasized Bluetooth Versions in one of the episodes of the Network+ series... Do I really need to mug up everything about that? Is the actual exam going to be very factual?
