CHAPTER 1: INTRODUCTION TO COMPUTER SCIENCE
1. Which of the following best defines computer science?
A. The study of computers and computational systems
B. The study of human interaction with computers
C. The design and development of computer hardware
D. The understanding of how to use a computer for everyday
tasks
Correct Answer: A
Rationale: Computer science is the study of computers and
computational systems, focusing on software and algorithms,
not just hardware or human interaction.
2. What is an algorithm?
A. A set of instructions for solving a problem
B. A type of software
, C. A mathematical equation
D. A programming language
Correct Answer: A
Rationale: An algorithm is a step-by-step set of instructions
designed to perform a task or solve a problem. It is foundational
to computer science and software development.
3. Which of the following is an example of an abstraction in
computer science?
A. A specific algorithm for sorting data
B. A hardware circuit
C. A computer programming language
D. The operating system interface
Correct Answer: D
Rationale: An abstraction simplifies complex systems by
providing a high-level interface. An operating system interface
hides the complexity of hardware management from users.
4. Which of the following best describes a programming language?
A. A method for solving a specific type of problem
B. A system that provides hardware support for computations
