Computer Science Fundamentals

What is the purpose of programming concepts?

• Programming concepts serve no practical or physical purpose .

• Programming concepts are designed to confuse users.

• Programming concepts are used for entertainment purposes only.

• Programming concepts provide a systematic way to understand and solve problems using code.

Explain the difference between front-end and back-end development.

• Front-end development is focused on security, while back-end development is focused on design.

• Front-end development deals with databases, while back-end development deals with user interfaces.

• Front-end development focuses on hardware, while back-end development focuses on software.

• Front-end development focuses on the client-side, while back-end development focuses on the server-side.

What is inheritance in object-oriented programming?

• Inheritance is a mechanism where a class inherits properties from an abstract class.

• Inheritance in object-oriented programming allows a new class to inherit properties and behavior from an existing class.

• Inheritance is a mechanism where a class inherits properties from an interface.

• Inheritance is a mechanism where a class inherits properties from a subclass.

What is the significance of variables in programming?

• Variables are insignificant in programming as they do not store any data

• Variables are unnecessary in programming as all data can be hardcoded

• Variables are only used for decoration in programming

• Variables are significant in programming as they store and manipulate data, enabling reuse and flexibility.

Describe the concept of polymorphism in object-oriented programming.

• Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.

• Polymorphism is a feature that allows objects to inherit properties from multiple classes.

• Polymorphism refers to the process of converting objects into primitive data types.

• Polymorphism is the ability of a function to only work with one specific object type.

What are the basic building blocks of a web page?

• Ruby

• Python

• PHP

• HTML, CSS, JavaScript

How does encapsulation contribute to the principles of object-oriented programming?

• Encapsulation makes it harder to maintain code in object-oriented programming

• Encapsulation does not allow for code reusability in object-oriented programming

• Encapsulation in object-oriented programming promotes data hiding, abstraction, security, modularity, and maintainability.

• Encapsulation leads to slower performance in object-oriented programming

What is the role of functions in programming?

• Functions are used for decorative purposes in programming

• Functions in programming are reusable code blocks that perform specific tasks, aiding in organization, reducing redundancy, improving readability, and enabling modularity and abstraction.

• Functions are not necessary and should be avoided in programming

• Functions are only used in advanced programming languages

Explain the importance of classes in object-oriented programming.

• Classes are important in OOP as they define the properties and behaviors of objects, enabling efficient and scalable software development.

• Classes only add complexity to software development

• Classes are used to define the properties of objects but have no impact on behaviors

• Classes are unnecessary in OOP and can be omitted

What are the key components of a programming language?

• vocabulary

• execution

• grammar

• syntax, semantics, pragmatics
