질문 # 117
What do IT professional organizations publish to offer morals by which individuals and companies abide?

정답:A

설명:
IT professional organizations publish codes of ethics to provide moral guidance for individuals and organizations working in the technology field. In Information Technology, a code of ethics outlines principles and standards of conduct related to responsibilities such as protecting privacy, ensuring security, avoiding harm, maintaining professional competence, being honest about system capabilities, and respecting intellectual property. These ethical standards help professionals make responsible decisions, especially when technical choices can affect users, society, or critical infrastructure. Regulations are legal requirements issued by governments and enforced through law. Policies are internal rules set by organizations to guide behavior within a specific company or institution. Bylaws are governance rules that define how an organization operates, such as membership, elections, and leadership structure, but they do not primarily serve as moral guidance for the broader profession. Professional ethics documents, on the other hand, are meant to guide behavior across the industry and promote trust and accountability. Therefore, the correct answer is ethics.


질문 # 118
Which component is part of the system unit?

정답:C

설명:
The system unit refers to the main computer case and the internal components housed inside it. In Information Technology hardware terminology, the system unit contains the core electronic parts required for processing and storage, including the motherboard, CPU, RAM, storage drives, power supply, and expansion cards. The motherboard is a central internal component of the system unit because it is the main circuit board that holds and connects major hardware parts through sockets, slots, and buses. By contrast, a keyboard is an external input peripheral, a monitor is an external output display device, and a printer is an external output peripheral used for hard-copy printing. While these peripherals are essential for user interaction, they are not considered part of the system unit itself. Understanding this distinction is important for tasks such as hardware troubleshooting, upgrades, and system assembly, where internal components are serviced within the system unit enclosure. Therefore, the component that is part of the system unit is the motherboard.


질문 # 119
A programmer needs to create a variable that holds the plus sign + for the addition operation. What is the name of the data type that should be used?

정답:A

설명:
A plus sign is a single symbol, so the correct data type is character. In Information Technology and programming fundamentals, a character data type is used to store exactly one character, such as a letter, digit, punctuation mark, or operator symbol. Examples include A, 7, #, and +. This differs from a character string, which stores multiple characters together, such as words, phrases, or product names. Integer and floating- point types are numeric and intended for arithmetic values, not symbolic operators. In many programming languages and database systems, characters are stored using an encoding standard such as ASCII or Unicode, allowing symbols like + to be represented consistently. Selecting the correct data type is important for validation and storage: a character field can be constrained to length 1, ensuring the variable cannot accidentally store multiple symbols or text. Because the requirement is to store a single plus sign symbol, the appropriate data type is character.


질문 # 120
How does application software differ from operating systems?
Choose 2 answers

정답:B,C

설명:
Application software and operating systems serve different purposes within a computer system. The primary distinction lies in their functionality and interaction with the computer's hardware and the user.
*Operating Systems (OS):
oAn OS is system software that acts as an intermediary between the user and the computer hardware.
oIt manages and coordinates the hardware components of a computer system, including the CPU, memory, storage devices, and peripheral devices.
oThe OS provides a platform for application software to run and facilitates user interaction with the system through a user interface.
oExamples include Microsoft Windows, Linux, and macOS.
*Application Software:
oApplication software consists of programs designed to perform specific tasks for the user.
oThese tasks can range from productivity applications like word processors and spreadsheets (Answer A) to communication tools like email clients (Answer B).
oUnlike the OS, application software does not manage hardware resources directly. Instead, it relies on the OS to provide these services.
oExamples include Microsoft Word, Excel, and Mozilla Firefox.
*Key Differences:
oApplication software is run by the end-user to perform specific tasks, while the OS runs in the background, managing the overall operation of the computer system.
oThe OS directly supports and manages the computer hardware system, which is not the case for application software.
References: The information provided here is verified through reliable sources that detail the differences between application software and operating systems12.


질문 # 121
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?

정답:C

설명:
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.
