I think that is the term.

I have an SD card with inbuilt wifi which allows "eye-fi" so you take a picture and it sends the picture to your PC (unknown details on even that) in "real time" so you don't have to keep taking the card out and putting it in the PC.

I shall try to search google, but hope it is ok to ask here for anyone who uses it and how to set it up.
But on the camera and what kind of PC you need. For now, the only "wifi connection" to the PC is via my home ADSL router. Is that how it works?

Thanks in advance.
