Introduction to SCSI technology

SCSI (Small Computer Standard Interface), pronouced "scuzzy", enable you to connect your computer to wide range of peripherals such as hard disks, CD-ROMS, printers and scanners. SCSI is the way peripherals communicate with the main processor of your computer.
Three advantages of SCSI are its speed, compatibility, and expansibility. In terms of speed, the fastest part of a computer is the processor, and SCSI gets its information in and out of the processor fast. And it keeps getting faster.

SCSI is highly compatible. All Macintosh® computers come with a SCSI port, and you can order many PCs with a SCSI port. If your computer has a SCSI port, you can get another device with the same type of SCSI, plug it in, and the new device should work. SCSI also makes it easy to expand. If you want to add an additional hard drive to your computer, just connect via the SCSI port. If you want to add another CD-ROM tower or a printer, just daisychain the additional devices up to seven or more.
