Chapter 5: SCSI Types & Specifications

Types of SCSI Signals:

The following table illustrates the evolution and capabilities of the various permutations of SCSI technology, as determined by the following criteria: For further clarification, please refer to the following definitions:

Interface: In this case, referring to a hardware interface - the physical connection between two pieces of hardware. For example, a USB keyboard connects peripherally to a host computer via the USB interface.

Throughput: A measurement used to identify the amount of data that can be transferred from one device to another, in a specified amount of time, typically measured in KB/s, MB/s etc.

Bus Width: A measurement used to determine the amount of data transmission, of which a device is capable. For example, a device with an 8-bit bus width can transmit 8 bits of data simultaneously, while a 32-bit device can concurrently transmit 32 bits of data per second.

Clock Speed: The speed at which a device can execute instructions, typically measured in MHz or GHz.

Maximum Number of Devices: The number of devices that can simultaneously be controlled from a single (in this case SCSI) interface.
