Quarters ad dimes, and lager denominations of coins, used to be made of silver, and a few of gold. The value of each coin was basically determined by the value of the silver or gold used to make it. Some people used to shave bits off each coin they received, thus accumulating valuable silver and gold for resale while reducing the real value of the coin being shaved.
The milling on the edges was added so that you could tell if someone was trying to palm off on you a coin that had been shaved that way and was, therefore, not worth the amount marked on it.
It's called "milling", and it's a historical relic. At one time, coins were made of precious metals (gold or silver). Unscrupulous people would shave the edges of coins and collect the shavings to melt down. Milling the edges makes it obvious that this has been done, and that the coin therefore wasn't worth full value. Neither quarters nor dimes still contain any gold or silver, but they're still milled, mostly because they've been that way for a long time, and ceasing to mill them would make them look "weird" to people at this point.

The ridges on the edges of dimes and quarters was designed to prevent both counterfeiting and 'clipping' -- the practice of shaving some of the metal off the edge, which would quickly add up, seeing as the coins were originally made of silver.
