The first successful attempt at making I/O self-managing by pushing intelligence into the interface was:

• SCSI-1
• SAM
• USB 1.0
• FC-AL

SCSI is the acronym for:

• Seagate Computer Systems Interface
• Shugart Corporation Systems Interface
• Small Computer Systems Interface
• Seagate Corporation System Interface

This company invented the Firewire interface:

• NCR
• Apple Computer
• Shugart
• IBM

IEEE 1394 supports the following transfer modes except:

• Asynchronous
• Isochronous
• Synchronous
• None of the above.

The first storage interface to break away from parallel connection was:

• SCSI 1.0
• SSA
• IEEE 1394
• Fibre Channel

In 1991, the European Organization for Nuclear Research invented:

• Parallel SCSI
• Firewire
• iSCSI
• Fibre Channel

FC-AL supports ___ MBps packet transmission in one direction, with a theoretical maximum of ___ devices in the loop.

• 100 / 127
• 1000 / 127
• 100 / 64
• 1000 / 64

A main disadvantage of iSCSI over Fibre Channel is:

• iSCSI is more expensive
• iSCSI is less secure
• protocol overhead of iSCSI
• distance limitations of iSCSI

The IEEE Industry Standard Architecture (ISA) bus was modeled after:

• PCI
• the PC/XT bus
• SCSI
• the general-purpose interface bus

The I/O interface that is an extension of the system bus is:

• PCI
• iSCSI
• fibre channel
• IEEE 1394 (Firewire)
