Sometimes the WNIC is tested as a 4 mark question, would be helpful to extend some points here... • Provide interface to wireless network • … as an antenna • Receives analogue radio waves • … convert them to digital / binary • Checks incoming transmissions for correct MAC / IP address • … ignore transmissions not intended for it • Encrypts / encodes the data • Decrypts / decodes the data • Takes digital/binary input and converts to analogue waves • … sends the radio waves via the antenna

Yes, WNIC could be a 4 mark question, but I think that was old past papers. Now these points are updated.
