Scsi Cable (or more commonly know as the ribbon cable)
A SCSI (Small Computer System Interface) cable is a type of data cable used to connect various peripheral devices, such as hard drives, scanners, and printers, to a computer. It facilitates communication between the computer and these devices, allowing for data transfer and command execution. SCSI cables can support multiple devices on a single connection and come in various forms, including parallel and serial types. Although less common today, SCSI was widely used in older computer systems for high-speed data transfer.

IDE (Integrated Drive Electronics) devices such as hard drives and DVD drives use this old flat cable type (PATA = Parallel AT Attachment). These are now generally replaced by SATA (Serial AT Attachment), which exploits improved data controller speeds. See PATA in wikipedia. SCSI cables for multiple devices can be flat as well.
Either SCSI or IDE (PATA).
Performance may suffer; the initiator (SCSI controller) may not see the SCSI targets (i.e, disks) ... or they may disappear at some really bad time; or performance might be great but you will get a lot of errors and data corruption ; The correct answer depends on a lot of variables including cable length; whether or not the controller and/or any of the disks are terminated; type of SCSI you use; quality of SCSI cabling; and SCSI device physical topology. Your computer may not even boot or spin up the whatever is connected to the SCSI controller. Bottom line, SCSI absolutely must be terminated properly. If it isn't, bad things may happen at unpredictable times.

To properly terminate a SCSI chain, you should place a terminator at the last device on the SCSI bus. This ensures that signals are correctly reflected and prevents data transmission errors. Depending on the SCSI type (like SCSI-1 or SCSI-2), the terminator can be a physical resistor pack or built into the device itself. Always check the SCSI specification for the specific requirements of your setup.
