Which of the following devices is used for accessing the data on Secure Digital (SD) card, MMC card, and CompactFlash (CF)?

Ebook Reader
Memory Card Reader
Smart Card Reader
BarCode Reader

Correct Answer

A. Memory Card Reader

Explanation

A memory card reader is used for accessing the data on Secure Digital (SD) cards, MMC cards, and CompactFlash (CF) cards. This device allows users to transfer data between their memory cards and other devices, such as computers or cameras. It provides a convenient and efficient way to access and manage the data stored on these types of memory cards.

Which of the following transmits all ATSC HDTV standards and supports 8 channel digital audio?

DVI
S-Video
SVGA
HDMI

Correct Answer

A. HDMI

Explanation

HDMI (High-Definition Multimedia Interface) is the correct answer because it is the only option that transmits all ATSC HDTV standards and supports 8 channel digital audio. DVI (Digital Visual Interface) only supports video signals and does not transmit audio. S-Video (Separate Video) and SVGA (Super Video Graphics Array) are both video-only interfaces and do not support digital audio. HDMI, on the other hand, is capable of transmitting high-definition video and audio signals, making it the appropriate choice for this requirement.

Which of the following can be used to accomplish authentication? Choose all that apply.

Biometrics
Encryption
Password
Token

Correct Answer(s)

A. Biometrics
A. Password
A. Token

Explanation

Biometrics, password, and token can all be used to accomplish authentication. Biometrics refers to the use of unique physical or behavioral characteristics, such as fingerprints or voice recognition, to verify a person's identity. Passwords are a common method of authentication, where a user must enter a secret code or phrase to gain access. Tokens, such as smart cards or security keys, provide an additional layer of authentication by generating one-time codes or acting as physical devices that must be present for access. Encryption, on the other hand, is a method of securing data, but it is not directly used for authentication.

Which of the following devices can cause great harm to one's life with lethal electric shocks? Choose Two.

SMPS
Floppy drive
Monitor
Keyboard

Correct Answer(s)

A. SMPS
A. Monitor

Explanation

SMPS (Switched Mode Power Supply) and Monitor can cause great harm to one's life with lethal electric shocks. SMPS is responsible for converting and supplying power to the computer components, and if it malfunctions or is handled improperly, it can deliver a lethal electric shock. Similarly, a faulty or damaged monitor can also pose a risk of electric shock, especially if there is exposed wiring or a damaged power cord. Both these devices involve high voltage components and should be handled with caution to avoid any harm.

Which of the following ports on a computer are used to connect a keyboard? Choose Two.

USB
DB-25
PS/2
DB-9

Correct Answer(s)

A. USB
A. PS/2

Explanation

USB and PS/2 ports are used to connect a keyboard to a computer. USB (Universal Serial Bus) is a common port that allows for easy connection and compatibility with various devices, including keyboards. PS/2 (Personal System/2) ports, although less common nowadays, were traditionally used for connecting keyboards and mice to computers. DB-25 and DB-9 ports are not typically used for connecting keyboards, but rather for other purposes such as serial or parallel communications.

Which of the following features are related to power management? Choose Two.

Hot plugging
Hibernate Mode
Standby Mode
Safe Mode

Correct Answer(s)

A. Hibernate Mode
A. Standby Mode

Explanation

Hibernate Mode and Standby Mode are both related to power management. Hibernate Mode allows the computer to save its current state to the hard drive and then power off completely, conserving energy. When the computer is turned back on, it will resume from where it left off. Standby Mode, on the other hand, puts the computer into a low-power state while still keeping the current session active. This allows for quick resumption of work while minimizing power consumption. Both features are useful for saving energy and extending battery life on laptops and other devices.

Which of the following are types of LCD monitors? Choose Two.

SVGA
Active Matrix
Passive Matrix
X-Matrix

Correct Answer(s)

A. Active Matrix
A. Passive Matrix

Explanation

Active Matrix and Passive Matrix are both types of LCD monitors. Active Matrix LCD monitors use a transistor for each pixel, allowing for faster response times and better image quality. Passive Matrix LCD monitors, on the other hand, use a grid of electrodes to control the pixels, resulting in slower response times and lower image quality compared to Active Matrix. X-Matrix is not a recognized type of LCD monitor, and SVGA refers to a resolution standard rather than a type of monitor.

You are handling IT support for a sales company. One of the sales reps complains that his laptop does not have a network card. You wish to add one via an expansion slot. What type of expansion card should you use?

MCA
PCMCIA
PCI
AGP

Correct Answer

A. PCMCIA

Explanation

PCMCIA (Personal Computer Memory Card International Association) is the correct expansion card type to use in this scenario. PCMCIA cards are commonly used for adding functionality to laptops, such as network cards, modems, or wireless adapters. They are designed to fit into the PCMCIA slot, also known as the PC card slot, which is found on most laptops. MCA (Micro Channel Architecture) is an outdated expansion card type used in IBM computers. PCI (Peripheral Component Interconnect) and AGP (Accelerated Graphics Port) are expansion card types used for desktop computers, not laptops.

Which of the following terms refers to an anti-virus software file that is updated from time to time to protect a computer from new viruses?

Definition
Modules
Service pack
Hotfix

Correct Answer

A. Definition

Explanation

An anti-virus software file that is updated from time to time to protect a computer from new viruses is commonly referred to as a "definition." Definitions contain information about the characteristics and behaviors of different viruses, allowing the anti-virus software to identify and remove them from the computer. Regularly updating the definitions ensures that the anti-virus software can effectively detect and protect against the latest threats.
