hope this helps..

No that doesnt help. People have to write down the address and go search so. Yeah I am assuming the answer is SD.

Answer 2

SD and SDHC fit in the same slot, but aren't necessarily interchangeable. A device or reader that can handle SDHC (SD high capacity) should read an SD card with no problem. But a device designed to use SD, may not recognize an SDHC card. There are some ways to deal with this. I have two card readers which will not read SDHC. There are very inexpensive SD cards up to 2GB in capacity, so I picked up one and it works all around. Card readers are inexpensive as well, but one of my existing ones would not be easy to replace. So I have a 4GB SDHC card that works in my camera and I could continue to transfer my photos from the camera to the PC by cable. But I bought an adapter to CF. So now I can use the SDHC in the camera and then slip it into the adapter before plugging into the CF slot of my readers. And I'm back in business. This sounds like a pain, but it's not. And I have another camera that uses CF anyway.

Just make sure the adapter says it will handle SDHC. Stores don't tend to carry (or know about) these adapters. I found mine online for about $15.

MMC I'm not familiar with. Sorry.
