What Is a PCMCIA Ethernet Card?
Ethernet cards provide a computer with a connection to a local area network (LAN). For many home computers the Ethernet adapter is built into the motherboard. Most laptops include PCMCIA slots that allow the user to insert and remove adapters easily. If the laptop does not have a built-in Ethernet adapter, then a PCMCIA Ethernet card would be needed to connect to a LAN.
