What's the purpose of a scanner that scan negative?

I am looking around for the best scanner to use to scan relatives photos for genealogy purposes. That way I can overrun the disk around to my siblings and they can print out what they want from their own personal computers. I ran across a scanner that debate about scan negatives and I'm curious as to why a scanner would scan negative. What do you do with scan negatives?

Answer:
You can scan negative from your old 35mm camera, invert the carving on your computer, and print the resulting pictures.

Every step away from the negative information (quality) is lost. So scan the negative is the best method to ensure a high level digital copy of the original.

i own a print shop and we use negative to burn printing plates for the offset press the plates are approaching film we expose to a extremely high pale so the image is if truth be told reversed in a cynical so when we burn it to a plate its positive again we use the for 4 color process work that requires very tight registration thats why we burn them to metal plates and you hold to have negative for that because they must be exactly right or the color wont look right or they will be blurry
