Not really computer but! I have just bought a digital camera and the book says I can use either SD or MMC cards up to 512MB capacity.What is the difference (except probably the price)? Which would you recommend?
The MultiMedia Card (MMC) was first on the scene and the Secure Digital (SD) followed - it can transfer data faster, is encrypted (hence the name) and you can also lock it, as with a floppy, to prevent it being overwritten.
Most SD devices such as digital cameras can also use MMC cards but it's not gospel and should be checked with the manual first.
