Obviously the D means digital. Single numeral cameras, like D1 or D3 are the pro line. Nikon's top of the line models. Double numeral, like D40 or D80 are consumer or more entry level cameras. Triple numeral, like D200 or D300 are semi pro, or high end enthusiast cameras. Within those guidelines the higher the number the most recent, or most advanced (the flaw is that Nikon went with D700 for their semi-pro FX model whereas a new numbering system would have made more sense since D300 was the top end DX sized). An s after a number, like D70s, means a second generation, usually meaning some sort of improvements, often a larger LCD or better focus system or something like that. An x after the number means a higher megapixel sensor version. An h in the name means high speed, or faster frame rate. Often accompanied with a lower megapixel sensor rating. The letters are sometimes combined. For instance, a D2 followed by a higher resolution D2x and a second generation D2x called a D2xs
