A handheld console created by Nintendo. It is the second successor to the Nintendo DS, and the 6th generation portable Nintendo gaming system. It features two (larger) screens, two cameras, and an online shop system. The menu is also overhauled, now using similar channels as used on the Wii.

DS Lite

The predecessor to the DSi. It came after the original DS PHAT and has a screen that can be set to 4x as bright as the DS PHAT.


The original Nintendo DS. It ended up being the successor to the Game Boy, though Nintendo did not intend for this to happen. It added a touch screen.

Hexadecimal (Hex)

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.



Internet Relay Chat; that is, realtime text-based chat over the Internet.
