Which wireless client devices require drivers to be installed on the client node?

• A. Wireless client devices on PC cards that are to be installed in PCI or ISA adapters
• B. All wireless client devices
• C. USB wireless adapters only
• D. Built-in laptop wireless modules only

Answer: (A)

Drivers are what let an operating system talk to hardware. Wireless devices on PC cards (the old PCMCIA type) typically need a specific driver to bridge the card’s chipset to the OS, especially when they’re installed in a PCI or ISA adapter. USB wireless adapters and built‑in laptop wireless modules are usually supported by the OS with generic or vendor-provided drivers that are already installed or install automatically, so they often don’t require manual driver installation. So in this context, the PC Card wireless devices that go into PCI or ISA adapters are the ones that commonly require driver installation on the client node.
