SCSI (Smart Computer System Interface)

SCSI stands for Small Computer System Interface. It is a set of specifications for connecting and moving data physically between computers and peripherals. Commands, protocols, electrical, optical, and logical interfaces are all defined under the SCSI standards.

Small Computer System Interface, or SCSI for short, is a set of American National Standards Institute (ANSI) standard electronic interfaces that enable personal computers (PCs) to communicate with peripheral hardware like disc drives, tape drives, CD-ROM drives, printers, and scanners more quickly and flexibly than earlier parallel data transfer interfaces. SCSI is pronounced SKUH-zee and is also sometimes referred to as “scuzzy.”


Ans. The “Shugart Associates System Interface,” created starting in 1979 and made public in 1981, is the ancestor of SCSI. Due to his innovative work at Adaptec and then Shugart Associates, Larry Boucher is regarded as the “father” of SASI and ultimately SCSI.

Ans. With SCSI, equipment like CD-ROM drives, scanners, DVD drives, and CD writers can perform better, transmit data more quickly, and expand more expansively.

Ans. SCSI drives are available in variants with 10,000 or 15,000 rotations per minute (RPM), thus it can access data considerably more quickly than your PC can (desktop drives are generally 5400 or 7200 RPM). SCSI is a fantastic option if you have small, mission-critical applications that must be accessible rapidly.
