SCSI-1 and SCSI-2 uses _______ pin type.

40
50
34
25
35

Correct Answer

A. 50

Explanation

SCSI-1 and SCSI-2 use 50-pin type. This means that the SCSI-1 and SCSI-2 interfaces are designed to use a 50-pin connector for data transfer. The 50-pin connector allows for a higher number of pins, which in turn allows for more data channels and higher data transfer rates compared to connectors with fewer pins. This makes the 50-pin type suitable for SCSI-1 and SCSI-2 devices that require faster and more efficient data transfer.

How many different I/O port addresses are there?

23
35,650
65,867
65,536

Correct Answer

A. 65,536

Explanation

There are a total of 65,536 different I/O port addresses. This is because an I/O port address is a numeric value used to identify a specific input or output port on a computer. In computing, a 16-bit address bus allows for a maximum of 65,536 unique addresses to be assigned. Therefore, there are 65,536 different I/O port addresses available.

What are express cards two width?

54mm and 34mm
25mm and 9mm
23mm and 36mm
53mm and 33mm

Correct Answer

A. 54mm and 34mm

Explanation

Express cards come in two different widths, which are 54mm and 34mm. These widths refer to the physical dimensions of the cards. The 54mm width is the standard size for most express cards, while the 34mm width is a smaller form factor used for certain specialized cards. The different widths allow for compatibility with various devices and systems, ensuring that express cards can be used in a wide range of applications.

Which function does a motherboard's chipset perform?

It facilitates communication between the processor, memory, and peripheral devices.
It controls devices and functions attached to the motherboard.
It maintains an accurate system time and date.
It initializes devices during the boot process.

Correct Answer

A. It facilitates communication between the processor, memory, and peripheral devices.

Explanation

The motherboard's chipset performs the function of facilitating communication between the processor, memory, and peripheral devices. This means that it allows these components to interact and exchange data effectively, ensuring smooth operation and efficient performance of the system as a whole. The chipset acts as a bridge, enabling seamless communication between different hardware components on the motherboard.

Which expansion slot is best for high-end dedicated video cards?

PCIe x1
PCIe x16
AGP
PCI-X

Correct Answer

A. PCIe x16

Explanation

The PCIe x16 expansion slot is the best for high-end dedicated video cards. PCIe stands for Peripheral Component Interconnect Express, and x16 refers to the number of lanes or data pathways available in the slot. The x16 slot provides the highest bandwidth and allows for faster data transfer, which is crucial for high-end video cards that require a lot of processing power. This slot is commonly used for gaming and graphics-intensive applications.

Which of the following objects is installed between the system case and the motherboard's back I/O ports?

Standoffs
Fan
Faceplate
Heat spreader

Correct Answer

A. Fan

Explanation

A fan is installed between the system case and the motherboard's back I/O ports. Fans are commonly used to cool down the components of a computer system by circulating air and preventing overheating. They are typically mounted on the system case and positioned near the motherboard's back I/O ports to ensure efficient cooling of the components, including the CPU and other heat-generating elements.

What is the name for the routine that tests the motherboard, memory, disk controllers, video, keyboard and other system hardware?

POST
CSST
BIOS
CMOS

Correct Answer

A. POST

Explanation

POST stands for Power-On Self Test. It is a routine that runs automatically when a computer is powered on. During the POST, the motherboard checks the hardware components such as memory, disk controllers, video, keyboard, and other system hardware to ensure they are functioning correctly. If any issues are detected, the POST will usually display error codes or messages to indicate the problem. Therefore, POST is the correct answer for the routine that tests the system hardware during the boot-up process.

Which security measure can be used to generate and store cryptographic keys?

DriveLock
Trusted Platform Module (TPM)
BIOS/UEFI password
Chassis intrusion detection

Correct Answer

A. DriveLock

Explanation

DriveLock is a security measure that can be used to generate and store cryptographic keys. DriveLock is a feature that allows users to encrypt their hard drives, protecting the data stored on them. By encrypting the drive, cryptographic keys are generated and stored securely, ensuring that only authorized users can access the data. This helps to prevent unauthorized access and protects sensitive information from being compromised.

What technology was designed to replace the BIOS and is a firmware solution for controlling the startup process and loading the computer operating system into memory?

CMOS
UEFI
EEPROM
BIOS 2

Correct Answer

A. CMOS

Explanation

CMOS (Complementary Metal-Oxide-Semiconductor) is not the correct answer for this question. CMOS refers to a type of technology used for constructing integrated circuits, including the BIOS (Basic Input/Output System). UEFI (Unified Extensible Firmware Interface) is the correct answer as it is a newer firmware solution that replaces the traditional BIOS and controls the startup process and loading of the operating system into memory. EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that can be electrically erased and reprogrammed, but it is not specifically designed to replace the BIOS.
