                                          WGU Introduction to IT Sample Questions (Q10-Q15):

                                          NEW QUESTION # 10
                                          What is the component of the data-information-knowledge-wisdom DIKW hierarchy that focuses on application?

                                          Answer: C

                                          Explanation:
                                          Knowledge is the DIKW component that focuses on application. In Information Technology, knowledge is often described as information that has been understood, combined with experience, rules, procedures, and context so that it can guide action. While information answers questions like who, what, where, and when, knowledge supports how to do something and how to solve a problem. For example, in infrastructure administration, information could be the list of server performance metrics, while knowledge includes understanding how to interpret those metrics and apply troubleshooting steps to restore normal operation.
                                          Data is raw and unprocessed, and information is processed data that has meaning in context. Wisdom is the highest level and involves judgment about what should be done, including ethical and strategic considerations.
                                          Knowledge sits between information and wisdom and is closely linked with practice, skills, and the ability to apply what is known to real tasks. Therefore, the DIKW level that focuses on application is knowledge.


                                          NEW QUESTION # 11
                                          What is one of the factors that determines the choice of an operating system?

                                          Answer: D

                                          Explanation:
                                          One major factor that determines the choice of an operating system is the device type. Operating systems are designed for specific categories of hardware and usage environments, such as desktop computers, servers, mobile phones, tablets, embedded devices, and network appliances. In Information Technology fundamentals, selecting an operating system begins with identifying the platform requirements, including processor architecture, memory limits, battery needs, and how the device will be used. For example, iOS and Android are designed for mobile devices, Windows and macOS are designed for desktops and laptops, and server operating systems are tuned for reliability, remote administration, and multi-user workloads. While driver compatibility is also an important consideration, many curricula treat it as a sub-factor related to hardware support within a chosen device category. Number of devices relates more to licensing and deployment planning, and coding language is not a direct determinant of which operating system must be used. Therefore, device type is a correct factor in choosing an operating system.


                                          NEW QUESTION # 12
                                          Which IT role is responsible for installing new hardware and troubleshooting existing hardware?

                                          Answer: A

                                          Explanation:
                                          *Explanation: System administrators manage the upgrade and installation of new hardware and software, perform troubleshooting to address any problems with computer systems, and assess viruses and potential threats to a company's network1.
                                          Therefore, the correct answer is D. System administrator.


                                          NEW QUESTION # 13
                                          What translates and executes source code into machine language one line at a time?

                                          Answer: A


                                          NEW QUESTION # 14
                                          Which software allows the user to easily access the hardware of a computer?

                                          Answer: D

                                          Explanation:
                                          *The software that allows the user to easily access the hardware of a computer is the operating system.
                                          *Explanation: The operating system serves as the interface between hardware, application software, and the user. It manages hardware resources, file systems, processes, and memory.
                                          *References: 12
                                          Therefore, the correct answer is C. Operating system.
