The original SCSI, as opposed to SCSI-2 or SCSI-3.
hardware A version of the SCSI command specification. SCSI-2 shares the original SCSI’s asynchronous and synchronous modes and adds a “Fast SCSI” mode (Wide SCSI” (16 bit, Another major enhancement was the definition of command sets for different device classes. SCSI-1 was rather minimalistic in this respect which led to various incompatibilities especially for devices […]
hardware An ongoing standardisation effort to extend the capabilities of SCSI-2. SCSI-3’s goals are more devices on a bus (up to 32); faster data transfer; greater distances between devices (longer cables); more device classes and command sets; structured documentation; and a structured protocol model. In SCSI-2, data transmission is parallel (8, 16 or 32 bit […]
- Scsi adaptor
hardware (Or “host adaptor”) A device that communicates between a computer and its SCSI peripherals. The SCSI adaptor is usually assigned SCSI ID 7. It is often a separate card that is connected to the computer’s bus (e.g. PCI, ISA, PCMCIA) though increasinly, SCSI adaptors are built in to the motherboard. Apart from being cheaper, […]
