FWDSCSI is an acronym that stands for "Forward SCSI" or "Fast and Wide Differential Small Computer System Interface." It refers to a type of SCSI (Small Computer System Interface) technology that was widely used in the late 1990s and early 2000s.
SCSI is a standard interface that allows computers to connect and communicate with peripheral devices, such as hard drives, tape drives, scanners, and printers. FWDSCSI, specifically, is an enhanced version of the original SCSI interface, designed to improve data transfer rates and increase the number of devices that can be connected to a computer system.
The "Forward" in FWDSCSI indicates the direction of data flow, emphasizing its bidirectional capability, allowing data to be transferred both from the computer to the peripheral device and vice versa. The term "Fast" refers to the increased speed at which data can be transferred compared to the older versions of SCSI.
"Wide" indicates the ability of FWDSCSI to support wider data paths, thus allowing for higher data transfer rates. This was achieved by increasing the width of the SCSI bus from 8 to 16 bits, thus doubling the data transfer rate.
"Differential" signifies the use of differential signaling in FWDSCSI. This means that it utilizes voltage differences to transmit data signals, which provides increased resistance to noise and interference and hence enhances reliability.
Overall, FWDSCSI is a type of SCSI interface that offers improved data transfer speeds, increased device connectivity, and better noise immunity, making it a popular choice during its era for high-performance storage devices and peripherals.
