How do laptop PCMCIA cards work?

So? I mean they manage to pack so much hardware capability into something so thin. e.g. the 3Com Megahertz cards have a 56K modem and a 100Mbit lan in one card... or wireless LAN..

Whats the technology behind it? Links to articles would be great
 
The actual chips that do these things are generally very small. You take a look at a Realtek 8139 NIC, the chip itself is the size of a coin! The only reason the cards are so big is because of the PCI connectors. In a PCMCIA card like that, the connectors don't make it as big as on a PCI card.


Confused
 
the reason pci cards are so big is because the card must be physically removed. it has to be handled, and not break into pieces.
