Glossary
root account
The standard IRIX login account reserved for use by the system administrator. This
account's home directory is the root (/) directory of the filesystem; the user of the root
account has full access to the entire filesystem (that is, that user can change and delete
any file or directory). The user of this account is sometimes referred to as the superuser.
root (/) directory
The directory at the top of the filesystem hierarchy.
screen
The portion of the monitor that displays information.
SCSI
Small Computer System Interface (pronounced "scuzzy"). SCSI is a high-speed
input/output specification for small computers. The Octane2 workstation is SCSI-3
compliant and supports two Ultra fast/wide/single-ended SCSI buses, each capable of
transferring data at 40 MB per second.
SCSI address
A number from one to seven that uniquely identifies a SCSI device to a system. No two
SCSI devices that are physically connected to the same SCSI bus can have the same SCSI
address.
SCSI address dial
A small plastic dial connected to some SGI external SCSI devices. Click its small buttons
to select a SCSI address for a new SCSI device.
SCSI bus length
The combined length of all internal and external SCSI cables in a system for each SCSI
bus.
SCSI cable
A cable that connects a SCSI device to a SCSI port on a workstation.
SCSI device
A hardware device that uses the SCSI protocol to communicate with the system. Hard
disks and floppy disks, CD-ROM drives, and tape drives are all SCSI devices. See also
SCSI.
