Common Plus Two Computer Application Practical Viva Questions and Answers for Hsslive Students
Below are ten frequently asked questions during Plus Two Computer Application Practical Viva examinations along with their appropriate answers:
Q: What is the difference between procedural and object-oriented programming?
A: Procedural programming focuses on procedures or functions that operate on data, while object-oriented programming organizes code around objects that contain both data and methods. OOP emphasizes concepts like encapsulation, inheritance, and polymorphism, making it more suitable for complex applications with reusable components, whereas procedural programming follows a top-down approach with a clear separation between data and functions.
Q: Explain the concept of normalization in database management.
A: Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves dividing larger tables into smaller ones and defining relationships between them. The main forms of normalization are First Normal Form (1NF), which eliminates repeating groups; Second Normal Form (2NF), which removes partial dependencies; Third Normal Form (3NF), which removes transitive dependencies; and so on. The goal is to minimize data duplication while ensuring data dependencies make logical sense.
Q: What is the difference between GET and POST methods in HTML forms?
A: The GET method appends form data to the URL, making it visible in the browser’s address bar and limiting the amount of data that can be sent. It’s suitable for non-sensitive data and is bookmarkable. The POST method sends form data in the HTTP request body, making it invisible in the URL and allowing for sending larger amounts of data. POST is more secure for sensitive information and is used when modifying data on the server.
Q: How does a web server communicate with a database in PHP?
A: In PHP, communication with a database typically involves several steps: First, establishing a connection to the database server using functions like mysqli_connect() or PDO constructors; second, selecting the database; third, preparing SQL queries; fourth, executing those queries; fifth, processing the results; and finally, closing the connection. PHP provides several APIs for database connectivity, including MySQLi and PDO, which help manage these interactions securely and efficiently.
Q: What is the importance of indentation in Python programming?
A: Indentation in Python is not just for readability but is syntactically significant. It defines code blocks in control structures like loops, conditionals, and function definitions. Proper indentation ensures that the interpreter correctly understands the scope and hierarchy of code blocks. Inconsistent indentation leads to IndentationError or unexpected behavior. Python’s use of indentation instead of braces or keywords to indicate blocks forces clean, readable code and reduces the possibility of syntax errors related to missing closing delimiters.
Q: Explain the concept of inheritance in object-oriented programming.
A: Inheritance is a fundamental principle in object-oriented programming where a class (called a subclass or derived class) can inherit attributes and methods from another class (called a superclass or base class). This promotes code reusability and establishes an “is-a” relationship between classes. For example, if we have a Vehicle class, classes like Car, Motorcycle, and Truck can inherit its common properties and methods while adding their specific characteristics. Inheritance enables hierarchical classification, polymorphism, and method overriding, making code more organized and maintainable.
Q: What are the different types of joins in SQL?
A: SQL supports several types of joins: INNER JOIN returns rows when there is a match in both tables; LEFT JOIN returns all rows from the left table and matched rows from the right table; RIGHT JOIN returns all rows from the right table and matched rows from the left table; FULL JOIN returns rows when there is a match in either table; and CROSS JOIN returns the Cartesian product of both tables. Each join type serves different purposes for combining data from multiple tables based on related columns.
Q: How would you handle exceptions in Python?
A: In Python, exceptions are handled using try-except blocks. The code that might raise an exception is placed in the try block, and the code that handles exceptions is placed in the except block. You can catch specific exceptions by naming them in the except statement or use a general except to catch any exception. Additionally, you can include finally blocks that run regardless of whether an exception occurred, and else blocks that run only if no exceptions occurred. This structure allows for graceful error handling and prevents program crashes.
Q: What is the difference between client-side and server-side scripting?
A: Client-side scripting executes in the user’s web browser (like JavaScript, HTML, CSS), providing interactive features without connecting to the server for every action. It enhances user experience but can be viewed and modified by users. Server-side scripting (like PHP, Python, Java) executes on the web server before sending content to the browser, handling tasks like database operations, user authentication, and session management. It’s more secure for sensitive operations since the code isn’t visible to users, but requires server processing for each operation.
Q: Explain the concept of CSS Box Model.
A: The CSS Box Model is a fundamental concept that describes how elements are rendered in web pages. It consists of content (the actual text or images), padding (clear space around the content), border (a line around the padding), and margin (clear space around the border). Each component can be sized individually using properties like width, height, padding, border-width, and margin. Understanding the box model is essential for controlling layout and spacing in web design. By default, the width and height properties only affect the content area, but this behavior can be modified using the box-sizing property.
