Which of the following expansion slots can be used to plug a SCSI adapter? Each correct answer
represents a complete solution. Choose all that apply.

A.
VESA

B.
Slot 2

C.
PCI

D.
Slot 1

E.
EISA

Explanation:

Small Computer System Interface (SCSI) adapters can fit on PCI, EISA, and VESA slots. Unlike IDE, SCSI
interface is generally not built-in on the motherboard. However, some motherboards do come with
integrated SCSI adapters. In most cases, you have to purchase a SCSI adapter and install it into a bus
slot. Once the SCSI adapter is installed, you can connect the SCSI devices to the host adapter.
What is SCSI?
Small Computer System Interface (SCSI) is the second most popular drive interface in use today after
the Integrated Drive Electronics (IDE) interface. SCSI is faster than IDE and supports more devices.
SCSI devices, such as hard disk drive and CD-ROM drive, are better suited in a network environment
in which many users access shared drives simultaneously. SCSI has three standards. SCSI-1, SCSI-
2,and SCSI-3.
What is a VESA bus?
VESA is an expansion bus standard developed by Video Electronics Standards Association to provide
high-performance video and graphics capabilities.
What is a PCI bus?
Peripheral Component Interconnect (PCI) is a high-performance, 32-bit or 64-bit bus designed to be
used with devices that have high bandwidth requirements, such as the display subsystem.
What is an EISA bus?
Extended Industry Standard Architecture (EISA) is a 32-bit PC expansion bus designed as a superset
of a 16-bit ISA bus.
The EISA bus is designed to increase the speed and expand the data width of the legacy expansion
bus while still supporting older ISA cards. This is accomplished by providing the slot with two layers
of connectors. The top layer is identical to a 16-bit ISA slot. The bottom layer is used by an EISA
device but ignored by an ISA device. Therefore, both ISA and EISA devices can work in an EISA slot.
Answer options B and D are incorrect. Slot1 and Slot2 are used for Pentium III processors and
Pentium Xeon processors, respectively.
