I'm pretty sure that I don't know! YOu better thank me for this

yes you can. at least in most cases. if you look on your motherboard (the biggest component of any computer internally), you'll see there is 2 (or 3)rectangular boxes right next to each other. that would be the hard disk/floppy disk bank. from each of the rectangles, there's a cord with a certain amount of pins. on each cord, there's (usually) 2 plugs that you can plug a hard disk or cd/dvd-rom into. there you have it.
Parallel ATA connectors use a 40 pin female connector with one pin removed for keying.
This is a data ribbon cable is used for computer drives, like hard disk drives, Optical disk drives, and floppy disk drives. They are also referred to as PATA cables. They connect to parallel ports consisting of 20 pins in one row, and 19 in the second, for a total of 39 pins. IDE cables are now considered old, having been largely replaced by SATA cables, which connect to newer drives which run at more RPM. The SATA system communicates more quickly that the PATA system using IDE cables.
Parallel ata cable connecter have 40 pins.
In Windows, you can look in 'device manager' in control panel. You can also use 3rd party software such as SiSoft Sandra. You can also pop the hood and check the connector style: Small, flat, thin with about 7 contacts is SATA. Large, wide/long with 40/80 pins/contacts, is IDE, or PATA.
It depends on the form factor of the disk itself. If it's a 2.5" laptop hard disk that runs off of (E)IDE (about 40-44 pins you'll see when disconnected) then usually it will be powered straight from the IDE bus. If it's SATA or (E)IDE on any other form factor (SATA 2.5" laptop/3.5" desktop or IDE 3.5" desktop disks) then they'll need a dedicated 5/12V power supply that usually can be provided by a computer's power supply unit or via a special power brick (if you're using a SATA/IDE to USB interface).
Differences between PATA and SATA hardrive are most visible in regards to the cables. A PATA hard drive has what is called a ribbon cable which is kind of big compared to the small SATA cable. The PATA ribbon cable has 40 pins that connect to the hard drive and/or motherboard whereas the SATA cable only has 7 pins allowing for the computer as a whole to be much cooler due to more empty space inside it for air to flow more freely. Also, I believe that the SATA drives are faster than IDE or PATA, especially if it is a SATA III which can transfer at speeds up to 6 gbs/per second.
