What is the purpose of a compiler in computer programming?

  1. To convert high-level programming language code into machine code

  2. To execute programs written in high-level programming languages

  3. To debug and fix errors in programs

  4. To manage memory allocation and deallocation


Correct Option: A
Explanation:

A compiler translates high-level programming language code into machine code, which can be directly executed by the computer's processor.

Which data structure is commonly used to store and organize data in a hierarchical manner?

  1. Array

  2. Linked List

  3. Stack

  4. Tree


Correct Option: D
Explanation:

A tree is a data structure that organizes data in a hierarchical manner, with nodes connected by edges. It is commonly used to represent hierarchical relationships, such as file systems or organizational structures.

What is the primary function of an operating system in a computer?

  1. To manage hardware resources

  2. To provide a user interface

  3. To run application programs

  4. To store data


Correct Option: A
Explanation:

An operating system's primary function is to manage hardware resources, such as memory, storage, and input/output devices, and to provide a platform for running application programs.

Which programming paradigm emphasizes the use of objects and classes to represent real-world entities?

  1. Procedural Programming

  2. Object-Oriented Programming

  3. Functional Programming

  4. Logic Programming


Correct Option: B
Explanation:

Object-Oriented Programming (OOP) emphasizes the use of objects and classes to represent real-world entities, allowing for modularity, encapsulation, and code reusability.

What is the process of breaking down a problem into smaller, more manageable subproblems called?

  1. Recursion

  2. Decomposition

  3. Iteration

  4. Abstraction


Correct Option: B
Explanation:

Decomposition is the process of breaking down a problem into smaller, more manageable subproblems, which can then be solved independently.

Which algorithm is commonly used for searching a sorted array?

  1. Linear Search

  2. Binary Search

  3. Breadth-First Search

  4. Depth-First Search


Correct Option: B
Explanation:

Binary Search is an efficient algorithm for searching a sorted array, as it repeatedly divides the search space in half until the target element is found.

What is the purpose of a loop in programming?

  1. To execute a block of code repeatedly

  2. To store data in memory

  3. To compare values and make decisions

  4. To input and output data


Correct Option: A
Explanation:

A loop in programming allows a block of code to be executed repeatedly until a certain condition is met.

Which data structure is commonly used to store and retrieve data in a first-in-first-out (FIFO) manner?

  1. Array

  2. Linked List

  3. Stack

  4. Queue


Correct Option: D
Explanation:

A queue is a data structure that follows the first-in-first-out (FIFO) principle, where the first element added is the first element to be removed.

What is the term for the process of converting a high-level programming language statement into machine code?

  1. Compilation

  2. Interpretation

  3. Execution

  4. Debugging


Correct Option: A
Explanation:

Compilation is the process of converting a high-level programming language statement into machine code, which can be directly executed by the computer's processor.

Which programming paradigm emphasizes the use of mathematical functions and expressions to solve problems?

  1. Procedural Programming

  2. Object-Oriented Programming

  3. Functional Programming

  4. Logic Programming


Correct Option: C
Explanation:

Functional Programming emphasizes the use of mathematical functions and expressions to solve problems, focusing on the evaluation of expressions rather than the execution of statements.

What is the purpose of a variable in programming?

  1. To store data temporarily

  2. To perform calculations

  3. To control the flow of a program

  4. To input and output data


Correct Option: A
Explanation:

A variable in programming is used to store data temporarily, allowing it to be accessed and modified throughout the program.

Which algorithm is commonly used for sorting an array of elements?

  1. Linear Search

  2. Binary Search

  3. Bubble Sort

  4. Merge Sort


Correct Option: D
Explanation:

Merge Sort is a divide-and-conquer sorting algorithm that repeatedly divides the array into smaller subarrays, sorts them, and then merges them back together to obtain the sorted array.

What is the process of identifying and fixing errors in a program called?

  1. Compilation

  2. Interpretation

  3. Execution

  4. Debugging


Correct Option: D
Explanation:

Debugging is the process of identifying and fixing errors in a program, typically involving testing the program, identifying the source of errors, and making necessary corrections.

Which data structure is commonly used to represent a collection of unique elements?

  1. Array

  2. Linked List

  3. Stack

  4. Set


Correct Option: D
Explanation:

A set is a data structure that stores a collection of unique elements, allowing for efficient membership testing and removal of elements.

What is the term for the process of translating a high-level programming language statement into an intermediate representation?

  1. Compilation

  2. Interpretation

  3. Execution

  4. Debugging


Correct Option: B
Explanation:

Interpretation is the process of translating a high-level programming language statement into an intermediate representation, which is then executed directly by the interpreter.
