VERY BASIC question about belts

My owner's manual for my 2001 Volvo S40 says to inspect my drive belt at 60K miles and change my timing belt at 110K miles. I was advised to go ahead and just have the drive belt changed since I drive 600-plus miles a week and just reached 57K miles. Now I'm confused as to what the drive belt is. I know the timing belt is the main belt. Is the drive belt a similar belt, or is it (possibly) several smaller belts that run the alternator, A/C compressor, power steering pump, etc?

So I am wondering, when I go into the shop, should I say, "I want the drive belt changed, " or should I say, "I want the drive belt and all the accessory belts changed"? I worry that if I sound like I don't know the difference, they'll think I'm a nitwit and take advantage of me. Thanks.
