QUESTION NO: 1

Which of the following is the bandwidth of an SCSI Ultra2 Wide I/O port?
A. 50 MBps
B. 160 MBps
C. 320 MBps
D. 80 MBps
Answer: D
Explanation:
The SCSI Ultra2 Wide I/O port has a bandwidth of 80 MBps.
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 drives and CD-ROM drives, are better suited to a network environment in which many users access shared drives simultaneously. SCSI has three standards: SCSI-1, SCSI-2, and SCSI-3.
Answer option A is incorrect. The IEEE 1394a S400 I/O port has a bandwidth of 50 MBps.
Answer option B is incorrect. The SCSI Ultra3 I/O port has a bandwidth of 160 MBps.
Answer option C is incorrect. The SCSI Ultra4 port has a bandwidth of 320 MBps.

QUESTION NO: 2
Which of the following hardware uses flash memory technology?
A. PCMCIA card
B. Smart card reader
C. Secure digital card
D. DDR2 SDRAM
Answer: C
Explanation:
Secure Digital (SD) card is a non-volatile memory card format used in portable devices such as mobile phones, digital cameras, and handheld computers. SD cards are based on the older MultiMediaCard
(MMC) format, but they are a little thicker than MMC cards. Generally an SD card offers a write- protect switch on its side. SD cards generally measure 32 mm x 24 mm x 2.1 mm, but they can be as thin as 1.4 mm. The devices that have SD card slots can use the thinner MMC cards, but the standard
SD cards will not fit into the thinner MMC slots. Some SD cards are also available with a USB connector. SD card readers allow SD cards to be accessed via many connectivity ports such as USB,
FireWire, and the common parallel port. It uses flash memory technology. Answer option A is incorrect. Personal Computer Memory Card International Association (PCMCIA) card is also known as
PC card. The PC card uses a small expansion slot and is primarily used in laptops. However, PC cards are also available in some of the desktop computers. It does not use flash memory technology.
Answer option D is incorrect. DDR2 SDRAM is a type of memory module. DDR2 SDRAM is an enhanced version of DDR SDRAM. It uses a 240-pin memory module and runs at the speed of 400
MHz or higher. It uses an operating voltage of 1.8 volts, instead of 2.5 volts used in DDR SDRAM. This results in less power consumption. DDR2 SDRAM transfers 64 bits of data twice every clock cycle.
DDR2 SDRAM memory is not compatible with DDR SDRAM memory slots. Answer option B is incorrect. A smart card reader is an interface device, which is used to read information from or write information to a smart card. It does not use flash memory technology.

QUESTION NO: 3
Which of the following statements about Hardware Compatibility List (HCL) are true?
Each correct answer represents a part of the solution. Choose two.

B. It contains the listing of all the hardware that operating systems vendors have tested with their operating systems.
C. It ensures that a computer and its components are working properly.
D. It contains the license to use operating systems.
Answer: A,B
Explanation:
The Hardware Compatibility List (HCL) contains the listing of all the hardware that operating systems vendors have tested with their operating systems. Through HCL, an administrator can be sure that a computer and its components are compatible with the operating system before the operating system is installed. HCL helps administrators to verify that the CPU, RAM, storage devices, various interface cards, and other hardware components are supported by the operating systems.
