A query allows the database administrator to retrieve specific data, such as recently updated entries, by using conditions and filters.
Question 92
Which of the following units of measurement is used when describing a gaming monitor?
Correct Answer: D
Gaming monitors are often described using refresh rates, which are measured in hertz (Hz), often specified in MHz for related processing frequencies. The CompTIA ITF+ FC0-U71 Official Study Guide states: "Monitor refresh rate refers to how many times per second the screen updates, usually measured in Hz." "MHz (megahertz) is used for various frequencies, including GPU and monitor refresh processing." GPU and RAM refer to hardware components, TB measures storage, and MHz relates to the frequency, applicable for monitor performance metrics. Reference: -
Question 93
A user wants to access books and does not need printed, physical copies. The solution should be portable and lightweight. Which of the following is the best solution?
Correct Answer: A
An e-reader is designed specifically for reading digital books in a portable, lightweight format: * "E-readers are mobile devices optimized for reading electronic books, offering portability, long battery life, and digital storage of thousands of titles." * Servers, external drives, and workstations are either not portable or not designed for reading books. Reference: CompTIA ITF+ FC0-U71 Official Study Guide, Chapter 4 - Computing Devices.
Question 94
A programmer creates a graphical representation of code components and the sequence for code execution. Which of the following has the programmer created?
Correct Answer: C
According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), a flowchart is explicitly defined as: "A flowchart is a visual representation of a program that uses boxes to represent the logic. Flowcharts are critical in the software development process. They should be created before the code is developed, much like blueprints should be drawn before building a house. They help the developers visualize the flow of the program, making it easier to plan out the sections of code needed." The guide further elaborates that: "Flowcharts show the order of operations within a program, including where data input is needed as well as decisions to be made and the logic choices. Different shapes are used to indicate different components. For example, a rectangle is used to indicate a process, whereas a diamond is used to show a decision point." This means the graphical depiction of how code executes step by step-including decisions and actions-is known as a flowchart, not pseudocode (which is text-based "fake code" for readability), nor branching or looping (which are logical control structures). Additionally, in the "Exam Essentials" section of the same guide, it reinforces that: "Understand what pseudocode and flowcharts are used for. Pseudocode is most often used to annotate the code with comments to make it easier for people to read. Flowcharts help organize the code and plan out a program." Verified Reference from CompTIA Tech+ Study Guide, Exam FC0-U71 (3rd Edition, 2025): * Chapter 6: Software Development Concepts - Sections "Flowcharts" and "Exam Essentials" (pages 373-374, 378).
Question 95
Which of the following utilities has the ability to remove drivers and scan for hardware changes?
Correct Answer: D
Device Manager in Windows is a system utility used to view and control the hardware attached to the computer. It allows users to uninstall, disable, and update device drivers, as well as scan for hardware changes. This utility is essential for managing the interactions between a computer's operating system and its hardware components.
