Q1. What is an algorithm?
a) A step-by-step procedure to solve a problem
b) A diagrammatic representation of a process
c) A programming language
d) A type of computer hardware
Show Answer
Correct Answer: a) A step-by-step procedure to solve a problem
Explanation: An algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. It is a plan for solving a problem.
Q2. Which symbol represents the decision in a flowchart?
a) Circle
b) Rectangle
c) Diamond
d) Parallelogram
Show Answer
Correct Answer: c) Diamond
Explanation: In a flowchart, the diamond symbol is used to represent a decision point, where a choice must be made between two or more paths.
Q3. What is the primary purpose of a flowchart?
a) To write computer programs
b) To provide a visual representation of an algorithm
c) To create graphical designs
d) To manage computer hardware
Show Answer
Correct Answer: b) To provide a visual representation of an algorithm
Explanation: A flowchart is a diagrammatic representation of an algorithm, which helps in understanding the flow of the process and the steps involved in solving a problem.
Q4. What is pseudocode?
a) A type of computer hardware
b) A high-level representation of an algorithm
c) A low-level programming language
d) A type of flowchart
Show Answer
Correct Answer: b) A high-level representation of an algorithm
Explanation: Pseudocode is a high-level, informal representation of an algorithm that uses a combination of natural language and programming constructs. It is used to describe the algorithm’s logic without the need for a specific programming language.
Q5. Which of the following is a low-level programming language?
a) Python
b) Java
c) Assembly language
d) JavaScript
Show Answer
Correct Answer: c) Assembly language
Explanation: Assembly language is a low-level programming language that uses mnemonics to represent machine code instructions. It is specific to a particular computer architecture and is used to write programs that interact directly with the hardware.
Q6. What is the primary difference between a compiler and an interpreter?
a) A compiler translates the entire program before execution, while an interpreter translates and executes one line at a time
b) A compiler is a type of programming language, while an interpreter is a type of computer hardware
c) A compiler is used for high-level languages, while an interpreter is used for low-level languages
d) A compiler is used for object-oriented languages, while an interpreter is used for procedural languages
Show Answer
Correct Answer: a) A compiler translates the entire program before execution, while an interpreter translates and executes one line at a time
Explanation: A compiler translates the entire source code of a program into machine code before execution, while an interpreter translates and executes the source code one line at a time during runtime.
Q7. What is the main advantage of a high-level programming language over a low-level programming language?
a) High-level languages are faster
b) High-level languages are easier to learn and use
c) High-level languages are more secure
d) High-level languages have better graphics capabilities
Show Answer
Correct Answer: b) High-level languages are easier to learn and use
Explanation: High-level programming languages are designed to be more user-friendly and easier to learn and use than low-level languages. They are closer to human language and provide higher levels of abstraction, which makes them more convenient for programmers.
Q8. What is an object-oriented programming language?
a) A language that focuses on objects and their interactions
b) A language that uses a procedural approach to programming
c) A language that is based on mathematical logic
d) A language that is designed for system programming
Show Answer
Correct Answer: a) A language that focuses on objects and their interactions
Explanation: An object-oriented programming language is a type of high-level language that focuses on objects and their interactions. It uses the concepts of classes, objects, inheritance, polymorphism, and encapsulation to model real-world entities and their relationships.
Q9. What is the role of a linker in the compilation process?
a) To translate high-level code into machine code
b) To execute the compiled code
c) To combine object files and resolve references between them
d) To check the syntax of the source code
Show Answer
Correct Answer: c) To combine object files and resolve references between them
Explanation: A linker is a program that combines object files generated by a compiler and resolves references between them to create an executable file. It ensures that all the required libraries and functions are linked correctly to the final executable.
Q10. Which of the following is an example of a high-level programming language?
a) Machine language
b) Assembly language
c) C++
d) Binary code
Show Answer
Correct Answer: c) C++
Explanation: C++ is a high-level programming language that provides a higher level of abstraction and is easier to learn and use than low-level languages like machine language or assembly language.
