If you mean can they read CD and DVD's then yes...most also can burn DVD's as well.....Vista is the operating system and comes with media centre and other programmes which allow you to copy DVD's, burn CD's etc....

it will if you ordered it with 1 but nowhere is it written in concrete that all new computers come with a dvd rom. if it's running vista it will at least have a dvd rom since vista comes on a dvd it's to bloated to fit on a cd.
Yes, computers now a days come with a DVD-RW drive (a.k.a a drive that you can watch DVD's on).

However, sometimes you need a decoder to watch DVD's on your computer.

For this, get Cyberlink PowerDVD Trial. You get 30 days, and after the trial, the decoder still is in your pc so you can watch DVD's with it.
i think you got a bit confused the hard disk the is the device that stores data. Most PCs now a days do come with a CD/DVD drive but just check when you buy it.
there is no such thing as a dvd hard drive, it will have a dvd drive yes. also it will be a dvdrw.
All new PC's nowadays have a DVD read/write drive in them. Even the cheap ones. If they didn't, they most likely wouldn't even sell!
yep current technology is dual layer. fastest practical (usable) speed is 16x dvd. You can get 18x but as far as I know its not actually possible to burn at that speed. yet.
