Definition

Noun: - A standardized hardware interface and communication protocol used to connect a computer to peripheral devices, such as hard disk drives, tape drives, scanners, and optical drives. It defines the commands, electrical signals, and physical connectors for data transfer.

Usage
  • As a noun (subject/object): SCSI is used to refer to the interface standard itself.
    • The old server uses SCSI for its hard drive connections.
    • We need to replace the failed SCSI in the system.
Advanced Usage
  • SCSI chain: A series of SCSI devices connected in a sequence to a single host adapter.
    • You must properly terminate the SCSI chain to avoid signal errors.
  • SCSI ID: A unique number assigned to each device on a SCSI bus for identification.
    • Ensure each device on the bus has a unique SCSI ID.
Variants and Related Words
  • SCSI-1: The original SCSI standard.
  • SCSI-2: An enhanced version with faster transfer rates and new commands.
  • SCSI-3: A later architecture comprising multiple separate standards (e.g., SPI, SASI).
  • SCSI controller (host adapter): The hardware component in a computer that manages the SCSI bus.
Synonyms
  • Parallel SCSI (specifically for the traditional parallel bus version).
  • Small Computer System Interface (the full form of the acronym).
Related Phrases
  • SCSI bus: The shared communication pathway connecting SCSI devices.
    • Too many devices on a single SCSI bus can slow down performance.
  • SCSI termination: The use of a resistor pack to prevent signal reflection at the end of the SCSI bus.
    • Improper SCSI termination was causing the data corruption.
Noun
  1. interface consisting of a standard port between a computer and its peripherals that is used in some computers
