SCSI (Small Computer System Interface) is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect other devices, including scanners and CD drives. An SCSI drive is usually referred to a disk drive that uses the SCSI standard interface and commands to connect and transfer data to/from the computer.
You can learn more about Peripheral Component Interconnect Express on Wikipedia, at the Hardware Secrets website and on How Stuff Works. The PCIe has replaced the older PCI-X.
A SCSI host adapter is a device used to connect one or more other SCSI devices to a computer bus. It is commonly called a SCSIcontroller, which is not strictly correct as any component understanding the SCSI protocol can be called a controller. It connects to the PCI Express.
The final SCSI device in the chain of devices must be terminated. If you have only one device and it's attached to a SCSI port, you must terminate that device. If you have two or more SCSI devices that are linked together and to a shared SCSI Port ie: SCSI Port, Device #1, Device #2, etc, then the final device in the 'chain' must be terminated to allow for proper recognition. The SCSI Port also requires a terminator as well.
Its a SCSI cable with a 50pin HD SCSI 2 connector on one side and a 68pin SCSI 3 connector on the other.
You change the ID of one of them. You change the ID of one of them.

single ended scsi is a method of transmitting electrical signals over wires. one wire carries a varying voltage that represent a signal, while other wire is connected to a ground. single emded scsi cables are of 6m-1.3m long. Differential scsi is a method of transmitting information electrically by means of 2 complementary signal pairs sent on 2 separate wires.
SCSI - Small Computer System InterfaceSCSI is an industry standard system interface, which allows multiple peripheral devices to be installed on the system. The number of devices that can be installed depends on the type of SCSI Host adapter that you have installed in your system. Most SCSI systems have an older "Narrow" 8-bit SCSI host adapter, which have 8-bit data paths and allow for up to 7 devices to be installed on the same channel. Newer "Wide" Host adapters have 16-bit wide data paths and provide support for up to 15 devices. A SCSI ID is a unique identifier assigned to each SCSI device on the bus. It determines the SCSI device's priority. There are 16 IDs, ranging from 0 to 15. The order of the priorities is a bit unusual. From highest priority to lowest they are: 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12 ,11, 10, 9, 8. ID 7 is almost always reserved for the SCSI Host Adapter. The other IDs are free to be assigned as desired, although your computer may have assigned them automatically.Never assign the same ID to more than one device.
For any Mac since hte original iMac: 1. A SCSI hard drive. 2. A PCI SCSI controller 3. An available PCI port SCSI controllers from Adaptec should have Mac OS binaries available. For any Mac prior to the original iMac: 1. A SCSI hard drive. 2. If using a non-Apple drive, a third-party formatting utility, or a patched Apple one.
The national retailer Staples offers SCSI cables for purchase in most of their stores. Online these cables can be bought at the web sites eBay, Amazon and Tiger Direct.
There is only one spindle per physical disk.
