The '''Small Computer System Interface''' (SCSI) is a previously popular type of bus to link digital storage media and other devices to computers. Introduced in 1986, this interface type is best know by its acronym, SCSI, which is pronounced "scuzzy."<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref><ref name="computerhope">https://www.computerhope.com/jargon/s/scsi.htm</ref> It is based on an older bus standard, Shugart Associates System Interface.<ref>https://computer.howstuffworks.com/scsi1.htm</ref>

Used internally, SCSI connections are made with a ribbon cable between the drive and the system's motherboard or storage controller card. External devices can also be connected to the storage controller card using a SCSI cable.<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>

==Interface types==
The following are some of the most common types of SCSIs which have existed.

*Fast SCSI: 10 MBps; connects eight devices<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>
*Fast Wide SCSI: 20 MBps; connects 16 devices<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>
*Ultra Wide SCSI: 40 MBps; connects 16 devices<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>
*Ultra3 SCSI: 160 MBps; connects 16 devices<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>
*Ultra-640 SCSI: 640 MBps; connects 16 devices<ref name="lifewire">https://www.lifewire.com/small-computer-system-interface-scsi-2626002</ref>

SCSI communication is much slower that modern standards, such as [[Serial ATA|SATA]], which is now commonly used in place of SCSI.
