The three most common types of wireless network interface adapters are
• PC or Express Card: This type of adapter is often used in laptop
computers because most laptops have one or two PC Card slots.
Figure 1-4 shows a PC Card wireless network interface adapter.
• USB: A Universal Serial Bus (USB) adapter connects to one of your
computer’s USB ports; these USB ports have been standard in just
about every PC built since the turn of the millenium.
• ISA or PCI adapter: If your computer doesn’t have a PC Card slot,
or USB port, you have to install either a network interface card or
a USB card (for a USB wireless network interface adapter) in one of
the computer’s internal peripheral expansion receptacles (slots).
The expansion slots in older PCs are Industry Standard Architecture
(ISA) slots. The internal expansion slots in newer PCs and Apple
Macintosh computers follow the Peripheral Component
Interconnect (PCI) standard.
More and more PDAs, laptops, and other devices are shipping with wireless
already onboard, so you don’t need an adapter of any sort. These devices
just come with the wireless installed in them. We tell you how to get your
wireless-enabled devices onto your wireless backbone in Part II.
