A term used to describe the base 16 number system, in which each digit represents four bits. After the digits 0-9, the letters A-F are used to represent the values 10-15. Hexadecimal is the preferred format for displaying binary data, as it is easy to mentally convert to/from binary and uses only 2 characters per byte.

SD Card
A common type of memory card, used by the 3DS, digital cameras, music players, etc. Stands for Secure Digital. The standard SD card has a maximum capacity of 2 gigabytes (2048 Megabytes); however, some 4GB cards exist but are rare. These cards usually do not have great compatibility with non-SDHC products, even though they are not SDHC, so 2GB is the size you should use.
SDHC
Stands for Secure Digital High Capacity Card. A type of SD card with a higher storage capacity than normal SD cards. These are theoretically capable of holding up to 2 terabytes of space, but are politically limited by the current standards to 32 gigabytes.
