SCSI, pronounced as scuzzy, stands for Small Computer System Interface. An SCSI port is used to attach peripheral devices that use the SCSI system , mainly for data transfer.
Three common standard interfaces CD-ROM drives use are IDE, SCSI, and USB. Newer interfaces may supplant these three for the lead.
oh sure,deffanetly connected both oh HDD in same pc, still configure function are different. first time formated the SCSI hard disk.then setup windows and another IDE formated over here and then SCSI's jumper put-up and put-in the IDE'S jumper and the restart the computer. Not only you can have a SCSi and IDE in the same computer but you can now use an IDE drive on a SCSI controller with proper adaptor http://www.addonics.com/products/io/ Most standard PC can have up to 4 IDE devices. You can use an Adaptec IDE RAID controller (like the 1210sa) and add 4 more in a single PC. Or you can use a SCSI adapter with IDE drives and SCSI to IDE converts to have up to 32 drives in a single computer (if you can fit them) Basically, all of the new low cost RAID boxes are made with SCSI to IDE converter using a SCSI controller. Now there is a difference in MTBF. The SCSI will last longer and work harder... as for speed the difference is not much anymore. For half the price and double the capacity, the IDE is still a deal (with the price of the SCSI to IDE adaptor) Ex 73GB SCSI $300 to $400 200GB IDE $120 As for installing it all depends on your system and OS. Depending if you need the SCSI to boot or just be a data drive. For ex when installing as a boot drive under win2000 you will need the driver on a floppy disk. At start up of the install press F6 so the driver will be loaded at the proper time in the installation.... Depending also if you are installing a RAID there will be a special bios setup (in the SCSI card) to set to mount the RAID. Hope this helps Yes
Traditionally motherboards were built with 2 on board IDE ports. However more and more mother board's are coming with 1 due to the use of SATA ports. The one IDE port i usually used for the CD-ROM.
Port 9000 is not pre-assigned to any function. It is the default port for the XDebug component used in many web development IDE's. www.xdebug.org
There are three common standards CD drives use to interface with a system. They are known as USB, SCSI and IDE. With the modern technology, new interfaces will come into play.

To some extent yes, the motherboard does indeed determine what kind of hard drive to install. Most modern motherboards will have SATA ports for the hard drives. The SATA ports are small in size and are usually labeled as SATA1-SATA4 or however many the motherboard has. You can read it right on the board. Older motherboards, however, used to use PATA or IDE hard drives (PATA & IDE are the same thing but with two different names). An IDE port on a motherboard is about 3-4 times the size of a SATA port. The really old boards may not have the IDE port labeled, but most other motherboards will have the letters IDE (or PATA) written next to the IDE port. If you're referring to a motherboard from the last 5-7 years, the chances are that it has SATA ports. The best thing to do is to look at the motherboard.

8 or 16 depending upon the SCSI hardware being used. In a narrow bus, you can use a SCSI ID of 0-7, and in a wide bus, you can use 0-15.
IDE: An older 'ribbon cable' parralel communication technology. It capped out at 133 MB/s transfer, and could have 2 devices plugged into 1 port (Master and Slave) sharing the same channel. Also known as EIDE (Enhanced IDE), ATA, and PATA (parralel ATA) SATA: Serial version of ATA (hence SATA) which comes in I, II, and III varieties, which operate at 1.5gbit, 3.0gbit, and 6.0gbit respectively (187.5MB/s, 375MB/s, and 750MB/s respectively). It supports Native Command Queing (NCQ), hotswap, and a few other features. It is noteably lower latency than IDE (quicker response time) and lower power. It's also cheaper and easier to plug in, using a smaller cable. SCSI: Small Computer Serial Interface (sometimes Small Cheap Serial Interface or similar) is a type of serial communication that predated SATA, and came out alongside IDE. It is now largely used only in servers, and not personal computers. It is an expensive interface (which is ironic for the name) and can provide speeds exceeding IDE and most SATA. Some versions such as SAS (Serially Attached SCSI) and FibreChannel use very high-speed and fiber optic links to acheive maximum speed. However, harddrives rarely exceed 150MB/s even in the world's fastest, 15,000 RPM harddrives. So such interfaces are rarely useful for single-drive soluitions. The advantage of SCSI is that is has (arguably) superior RAID support, allowing multiple drives to act as one, and combine their power, or to mirror each other for data redundancy backup. It can also be 'daisy chained', connecting one drive ontop of another in a chain to a single port, thus allowing many drives with less individual cables and easier management and organization.
It depends on the type interface you would be using, IDE, SATA, SCSI (or a combination of these). Generally, most motherboards use IDE (or UIDE), which has two IDE Ports each of which supports two drives (Master and Slave), be they hard disks, CD or DVD drives. So the answer is four. However, a type of motherboard known as "RAID" which is short for Redundant Array of Independent (or Inexpensive) Disks, can have double that number. These are used for servers, but can be used for personal computers although not normally necessary, as they do not function in quite the same as the conventional IDE arrangement.
