I. Technology Basics and Hardware Concepts
1. Which hardware component is specifically responsible for rendering images,
animations, and video for the monitor?
A) CPU
B) RAM
C) GPU
D) SSD
Correct Answer: C
Explanation: The Graphics Processing Unit (GPU) is specifically designed to handle
visual rendering tasks. Although the CPU (A) handles general-purpose computing, it is
not as efficient as the GPU when processing large amounts of parallel graphics
operations. RAM (B) is temporary storage, and SSD (D) is persistent storage .
2. A user's newly installed graphics card fan spins, but the operating system
does not recognize it. What is the most likely hardware cause that should be
checked first before reinstalling drivers?
A) Reinstall the operating system
B) Replace the monitor cable
C) Check whether the graphics card's auxiliary power connectors are securely
connected
D) Replace the motherboard
Correct Answer: C
Explanation: The fan spinning indicates that the graphics card is receiving basic slot
power, but high-end graphics cards typically require additional 6-pin or 8-pin auxiliary
power. If the auxiliary power is not connected, the card may not function properly or be
recognized. This is a more fundamental hardware issue than drivers or the operating
system .
,3. What is the primary function of an HDMI port?
A) Transmit digital high-definition video and multi-channel audio over a single cable
B) Connect a printer
C) Transmit analog audio signals
D) Supply power to external devices
Correct Answer: A
Explanation: HDMI (High-Definition Multimedia Interface) is designed to transmit
uncompressed digital video and audio signals over a single cable. It is the standard
interface for connecting monitors, TVs, and projectors .
4. Regarding the seven principles of universal design for hardware, which two
of the following are core principles? (Select 2)
A) Pursue lowest cost, using the cheapest components
B) Equitable use: the design is useful and marketable to people with diverse abilities
C) Tolerance for error: minimize hazards and adverse consequences of accidental
actions
D) Mandatory integration of Internet of Things functionality
Correct Answer: B, C
Explanation: The principles of universal design include equitable use, flexibility in use,
simple and intuitive use, perceptible information, tolerance for error, low physical
effort, and size and space for approach and use. A is a business goal, not a design
principle; D is not a universal requirement .
II. Digital Citizenship and Information Management
5. In a search engine, what is the function of placing a search term in double
quotes (e.g., "machine learning")?
A) Exclude pages containing that term
B) Search only for images
C) Perform an exact phrase match
D) Search for synonyms of the term
Correct Answer: C
Explanation: Double quotes force the search engine to return pages containing that
exact phrase in the same order. The tilde (~) is used to search for synonyms .
6. When evaluating the credibility of a web page, which of the following is the
most important judgment criterion?
A) Whether the page design is aesthetically pleasing
B) Whether the author or organization is authoritative, and whether sources are cited
C) Whether the page contains a large number of images
D) Whether the page appears at the top of search results
,Correct Answer: B
Explanation: The core of credibility evaluation includes the author's authority, the
presence of evidence and references, the timeliness of the content, and the objectivity of
the viewpoint. Visual design or search ranking does not guarantee the accuracy of the
content .
7. Which of the following best describes the concept of a "digital footprint"?
A) The storage space occupied by a computer's hard drive
B) The trail of data left behind by a user's online activities, including posts, browsing
records, and purchases
C) The number of software programs installed on a device
D) The speed of network data transmission
Correct Answer: B
Explanation: A digital footprint refers to the cumulative data traces generated by a
user's online behavior. It is persistent and searchable, so attention must be paid to
privacy management .
III. Content Creation and Collaboration
8. Which of the following is an example of asynchronous collaboration?
A) Two people editing the same document in real time and seeing each other's
changes immediately
B) One person edits a file, saves it, and sends it to another person via email for later
editing
C) Holding a video conference meeting
D) Using a shared whiteboard for real-time drawing
Correct Answer: B
Explanation: The characteristic of asynchronous collaboration is that participants do
not work simultaneously. Real-time collaborative editing, video conferencing, and real-
time whiteboards are all synchronous collaboration .
9. In spreadsheet software, which function is used to calculate the average of a
range of cells?
A) SUM
B) AVERAGE
C) COUNT
D) MAX
Correct Answer: B
Explanation: The AVERAGE function calculates the arithmetic mean. SUM performs
summation, COUNT counts the number of cells containing numerical values, and MAX
finds the maximum value .
, 10. Which of the following is a best practice when creating a presentation?
A) Fill each slide with dense text
B) Use a structured outline to organize content, paired with concise text and
meaningful visuals
C) Use the same color scheme for all text and background
D) Add as many animations and sound effects as possible
Correct Answer: B
Explanation: Presentations should be centered on the audience, using an outline to
organize the logical structure, maintaining concise text and high-contrast visual design
to improve readability and accessibility .
IV. Communication and Network Fundamentals
11. In email, what is the difference between CC and BCC?
A) CC recipients are visible to everyone, BCC recipients are hidden
B) CC is used for attachments, BCC is used for the body text
C) CC is for internal use, BCC is for external use
D) There is no difference; both are identical
Correct Answer: A
Explanation: CC (Carbon Copy) recipients' email addresses are visible to all recipients;
BCC (Blind Carbon Copy) recipients' addresses are hidden and invisible to other
recipients .
12. What is the most appropriate first step when receiving a suspicious email
attachment from an unknown sender?
A) Open it immediately to check the content
B) Do not open it; verify the sender's identity through another channel (e.g., phone)
C) Forward it directly to colleagues
D) Reply to the email asking the sender to resend
Correct Answer: B
Explanation: Suspicious attachments may contain malware or phishing programs. The
safe practice is not to open them and to verify through independent channels .
13. What is the primary risk of using unsecured public Wi-Fi?
A) The device battery drains faster
B) Data sent (such as passwords) may be intercepted by other users on the same
network
C) The screen resolution decreases
D) The hard drive capacity decreases
Correct Answer: B
Explanation: Unsecured public Wi-Fi typically lacks encryption, and data transmitted
