SCSI -Small Computer System Interface

SCSI (Small Computer System Interface) is a standard for connecting and transferring data between computers and peripheral devices.

Here's a breakdown:

• Key Features:

  • High Performance: Known for its high data transfer speeds, making it suitable for demanding applications.

  • Versatility: Connects a wide range of devices, including hard drives, scanners, CD-ROM drives, and tape drives.

  • Multiple Devices: Allows multiple devices to be connected to a single SCSI controller.

• Types of SCSI:

  • Parallel SCSI: The original type, using parallel cables to transmit data.

  • Serial Attached SCSI (SAS): A more modern version using serial cables, offering higher speeds and improved performance.

  • Fibre Channel: A high-speed, long-distance technology that can transport SCSI commands.

• Decline in Use: While historically significant, SCSI has largely been replaced by other technologies like SATA (Serial ATA) for most consumer and small business applications. SATA offers comparable performance at a lower cost and with simpler cabling.

In essence, SCSI was a pioneering technology that played a crucial role in the development of high-performance computing. While its dominance has declined, it remains relevant in certain niche applications and enterprise environments.
