DOMAIN I: IT FUNDAMENTALS & SYSTEMS THINKING (Q1-40)
1. Assembly and machine language are examples of which type of
programming language?
A) High-level programming languages
B) Low-level programming languages
C) Scripting languages
D) Markup languages
**Answer: B**
Rationale: Assembly and machine language are classified as low-level
programming languages because they are closely tied to the computer's
hardware architecture and provide little abstraction from the
machine's instruction set.

,2. JavaScript, Python, PHP, and JSP are examples of what type of
programming language?
A) Low-level programming languages
B) Compiled programming languages
C) Scripting languages
D) Machine languages
**Answer: C**
Rationale: JavaScript, Python, PHP, and JSP are scripting languages.
They are typically interpreted at runtime rather than compiled
ahead of time, and they are often used to automate tasks or
generate dynamic web content.
3. BASIC, C, C++, FORTRAN, and LISP are examples of which kind of
programming language?
A) Low-level programming languages
B) Assembly languages
C) High-level programming languages
D) Scripting languages
**Answer: C**
Rationale: BASIC, C, C++, FORTRAN, and LISP are high-level
programming languages. They use human-readable syntax and provide
significant abstraction from machine architecture, making them
easier to write and understand than assembly or machine code.
4. A system comprised of different parts working together to accomplish
a goal is known as what?
A) Information Technology
2
, B) Computer Science
C) Software Engineering
D) Data Communications
**Answer: A**
Rationale: This is the foundational definition of Information
Technology (IT). IT encompasses the use of hardware, software,
networks, and data systems that work cohesively to achieve a
specific objective or solve a problem.
5. Which of the following best describes the "Input-Process-Output" model
in an IT context?
A) A system that only stores data without transforming it.
B) A cyclical model where data is entered, manipulated, and results
are produced.
C) A model specifically for networking protocols.
D) A security framework for encryption.
**Answer: B**
Rationale: The IPO model is fundamental to understanding how IT
systems function: raw data enters (Input), is processed (CPU/
Software), and meaningful information is produced (Output).
6. An organization uses a cloud-based inventory system that updates
automatically when a sale is made. This integration of hardware,
software, and data to support business operations is an example of:
A) A standalone desktop application.
B) A manual ledger system.
C) An Information System.
3
, D) A data silo.
**Answer: C**
Rationale: An Information System is a combination of hardware,
software, data, people, and processes that work together to support
business functions.
7. Which of the following is a primary characteristic of "systems
thinking" in IT?
A) Focusing solely on individual components without regard to
interactions.
B) Understanding the interrelationships between components and how
they affect the overall system.
C) Prioritizing hardware costs over software efficiency.
D) Eliminating all feedback loops.
**Answer: B**
Rationale: Systems thinking involves viewing the "big picture" by
understanding how each component interacts and affects the entire
ecosystem.
8. What is the primary purpose of an IT infrastructure?
A) To provide a physical and virtual framework to deliver IT services.
B) To strictly manage financial transactions.
C) To replace all human workers.
D) To design user interfaces.
**Answer: A**
Rationale: IT infrastructure encompasses all hardware, software,
networks, and facilities required to develop, test, deliver, monitor,
