What is the SCSI-1 transfer rate and how many bits does it support?

10 MB/sec and 16 bits
5 MB/sec and 8 bits
20 MB/sec and 8 bits
40 MB/sec and 16 bits

The correct answer is: 5 MB/sec and 8 bits

The SCSI-1 standard, which was introduced in the mid-1980s, supports a transfer rate of 5 MB/sec and utilizes an 8-bit data bus. This means that during a single data transfer operation, SCSI-1 can move 5 megabytes of data per second using an 8-bit width, allowing for effective communication between the host and the connected devices. Understanding this standard is crucial because it sets the foundation for later SCSI versions, which increased data transfer speeds and bit widths. The characteristics of SCSI-1 are essential for recognizing how storage links have evolved in computing technology.
