I'm fairly new to laptops and I'm getting my first in a couple days, so I've been looking around the 'net for information. I've come across a bunch of things that I don't understand.
First, what is a port replicator? How does it help reduce cpu heat? What else does it do? Is it worth it to get one?
Is a 3Com Mini-PCI card a port replicator? It's pointed out by Dell on their webpage when you click on the Inspiron 4000 series. It helps reduce power consumption and preserve battery life; how exactly does that work? And where would it go on the laptop?
Network cards: What do 16-bit, 32-bit, PCMIA, PC Card, and Type I or II mean? What's the difference? Which would I need for my laptop? If my laptop has a hole for a Cat-5 cable, but no internal network card, would it be possible to order one and install it myself?
Processors: What's the difference between desktop processors and mobile? How do I know which I have?
That's all I have for now, thanks guys for takin' the time to read this, I really appreciate it.
