Does a wireless card (for my laptop) do the same thing as the usb adaptor ?

Question

how is a wireless card put into the laptop ?

Answer 1

If you purchase a wireless card for a laptop, you must get a PCMCIA wireless card.  Desktop computers use PCI or PCI-E cards.   There is a slot, usually on the side of a laptop that you can insert a PCMCIA card.  You can also get USB wireless network cards that do the same thing but plug into the USB port.  It's what ever your preference is.

Answer 2

No.

Your Wireless Adapaptor will work in Parallal Data accessing mode.

But Your USB will work on Serial Data Accessing Mode
