                                          WGU Introduction to IT Sample Questions (Q11-Q16):

                                          NEW QUESTION # 11
                                          Which component comes in two varieties, one that mechanically writes binary data onto spinning magnetic disks and one that writes data with no mechanical parts?

                                          Answer: D

                                          Explanation:
                                          The hard drive category includes two common storage varieties: traditional hard disk drives and solid-state drives. A hard disk drive stores binary data magnetically on spinning platters and uses mechanical parts such as a rotating motor and moving read and write heads. In contrast, a solid-state drive stores data using non- volatile flash memory with no moving mechanical components. In Information Technology hardware concepts, both serve the same role as secondary storage, meaning they store files, applications, and the operating system persistently even when power is off. Hard disk drives are often lower cost per gigabyte and are common in large-capacity storage, while solid-state drives provide faster access times, improved performance, and better resistance to physical shock. The motherboard is the main circuit board, the system clock provides timing pulses, and an expansion bus is a communication pathway for add-on devices. Since the question describes mechanical and non-mechanical storage types, the correct component is the hard drive.


                                          NEW QUESTION # 12
                                          Which type of high-level language translates the entire program at once?

                                          Answer: C

                                          Explanation:
                                          Compiled languages follow this process:
                                          1.Source Code: You write code in a high-level language (like C++, Java, or C#).
                                          2.Compiler: A compiler translates the entire source code into machine-executable code (object code) at once.
                                          3.Executable File: The object code is often packaged into an executable file.
                                          4.Execution: The executable file can be run directly by the computer's operating system.


                                          NEW QUESTION # 13
                                          What is an advantage of insourcing?

                                          Answer: A

                                          Explanation:
                                          Insourcing, the practice of developing software or handling IT tasks within the organization, offers several advantages. The primary advantage in this scenario focuses on skill development:
                                          *Knowledge growth: By working directly on projects, in-house developers gain hands-on experience, enhancing their coding skills and understanding of the company's specific needs.
                                          *Ownership: Insourcing provides developers with a sense of ownership over the project, often leading to increased motivation and problem-solving skills.


                                          NEW QUESTION # 14
                                          A programmer is working with Perl. Which type of language is this?

                                          Answer: D

                                          Explanation:
                                          Perl is generally categorized as an interpreted language. In Information Technology, Perl is a scripting language that is commonly executed by the Perl interpreter, which reads the source code and runs it without requiring a separate compilation step that produces a standalone executable in the typical compiled-language workflow. This makes Perl useful for tasks such as text processing, automation, system administration scripting, and rapid prototyping. Interpreted execution supports quick testing and modification because developers can run scripts immediately after editing. While some interpreted languages can be compiled into intermediate bytecode or packaged into executables, the standard and most widely taught model for Perl is interpreter-based execution. Assembly language is a low-level mnemonic representation of machine instructions, and machine language is binary code executed directly by the CPU. Perl does not fit those categories. Compared to compiled languages like C, Perl emphasizes flexibility and scripting convenience.
                                          Therefore, the correct classification for Perl in this context is interpreted language.


                                          NEW QUESTION # 15
                                          Which category of software allows other types of software to interface with the computer hardware?

                                          Answer: B

                                          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.
