PC-Card is the 'Version 2' of PCMCIA. It was released about 4 years ago.
I don't know of any new laptops that use PCMCIA instead of PC-Card. The odds are that your laptop has a PC-Card slot & not PCMCIA.
A PCMCIA card will work in a PC-Card slot but a PC-Card won't work in a PCMCIA slot.
Generally a PC-Card looks the same as a PCMCIA device with the addition of a row of bumps at the connector end.
The main differences betwen the two specifications:
PCMCIA: . .16 bit, 8MHz ISA bus, 5V. .The slot can't accept the newer PC-Cards
PC-Card: . .32bit, 33MHz PCI bus, 3.3V. .The slot can is backwards compatible with older PCMCIA cards
