question 254

Multiple Choice

SCSI interfaces provide for faster data transmission rates (up to 80 megabytes per second) than standard serial and parallel ports. In addition, you can attach many devices to a single SCSI port, so that SCSI is really an I/O bus rather than simply an interface Which two statements about SCSI are true?

• A) The bus is limited to 64 devices.
• B) It is a full-duplex serial standard.
• C) It is a half-duplex serial standard.
• D) It allows up to 320 MB/s of shared channel bandwidth.
