WGU Introduction to IT Sample Questions (Q13-Q18):

NEW QUESTION # 13
Which operating system component dictates how the operating system is perceived?

Answer: D

Explanation:
The user interface dictates how the operating system is perceived because it is the part of the system that users directly interact with. In Information Technology, the user interface can be graphical, such as windows, icons, menus, and pointers, or command-line, where users type commands. This interface shapes the user experience by controlling how tasks are performed, how information is displayed, and how users navigate files, settings, and applications. While the kernel performs critical background functions such as memory management, process scheduling, and hardware control, most users do not interact with it directly. The file manager is an important utility for handling files and folders, but it is a subset of the overall user interface experience.
Drivers are also mostly invisible to users and operate behind the scenes to enable hardware devices to work correctly. Because the user interface is the visible layer through which the operating system communicates with the user, it most strongly determines how the operating system is perceived. Therefore, the correct answer is user interface.


NEW QUESTION # 14
What is the role of the CPU in a computing environment?
Choose 2 answers

Answer: A,D

Explanation:
1.Arithmetic Logic Unit (ALU):
oThe ALU is a critical component within the CPU. It performs various arithmetic operations (such as addition, subtraction, multiplication, and division) and logic operations (such as comparisons, AND/OR operations, and shifting).
oWhen you perform a calculation on your computer, the ALU processes the numbers involved and produces the result.
oFor example, when you add two numbers in a spreadsheet, the ALU handles the addition operation.
2.Instruction Execution:
oThe CPU executes instructions based on machine code (binary signals represented as 1's and 0's).
oThese instructions come from software programs (applications), the operating system, or other components.
oThe CPU fetches an instruction from memory, decodes it, performs the necessary operation (using the ALU), and then stores the result.
oThis process happens at an incredibly fast rate, allowing your computer to perform complex tasks seamlessly.
3.System Bus:
oThe CPU communicates with other components (such as RAM, storage devices, and peripherals) through the system bus.
oThe system bus consists of three types:
Control Bus: Facilitates communication between the CPU and other devices.
Data Bus: Transfers data between different components.
Address Bus: Identifies memory locations for data access.

NEW QUESTION # 15
Which hardware component provides electric pulses that electronic components need in order to operate?

Answer: A

Explanation:
The system clock provides the electric timing pulses that electronic components use to coordinate operations.
In Information Technology hardware architecture, digital circuits require a consistent timing signal to synchronize actions such as executing CPU instructions, transferring data across buses, and coordinating memory access. The clock signal is a repeating electrical waveform that establishes a rhythm for the system, allowing components to perform steps in a controlled sequence. CPU speed is commonly measured in cycles per second, such as gigahertz, which reflects how many clock cycles occur each second. While the motherboard contains circuits and connectors that distribute signals, and expansion buses carry data between components, they do not generate the fundamental timing pulses. A hard drive stores data and does not provide timing for the overall system. Because the question asks specifically about providing electric pulses required for operation, it refers to the system clock function that produces and distributes the timing signal.
Therefore, the correct answer is system clock.


NEW QUESTION # 16
What are two signs of a phishing e-mail?
Choose 2 answers

Answer: A,B

Explanation:
1.Poor grammar and spelling errors: Phishing emails often contain mistakes in language, grammar, or spelling.
These errors can be a red flag that the email is not legitimate.
2.An email from an organization you don't recognize: Be cautious if you receive an email from an unfamiliar organization. Verify the sender's legitimacy before taking any action.

NEW QUESTION # 17
Which category of software allows other types of software to interface with the computer hardware?

Answer: C

Explanation:
System software is the category that allows other software to interface with computer hardware. In Information Technology, system software includes the operating system, device drivers, and utility programs that manage hardware resources and provide a platform for applications. Applications such as word processors and web browsers do not communicate directly with hardware like the CPU, memory, storage devices, or printers. Instead, they use services provided by the operating system and drivers. The operating system manages processes, memory, and input and output operations, while device drivers translate general commands into device-specific instructions for hardware components. This layered design improves reliability and security by controlling access to hardware and standardizing how applications request resources. Productivity software refers to applications that help users perform tasks, and collaboration software supports communication and teamwork, but neither category provides the core hardware interface.
Shareware is a distribution and licensing model, not a hardware interface layer. Therefore, the correct category is system software.
