Question 1: What is cyber security? (1 mark) Answer: Cyber security refers to the practice of protecting computer systems, networks, and data from digital attacks, unauthorized access, and information theft.

Question 2: Differentiate between compiler and interpreter. (2 marks) Answer:

1. Compiler translates the entire source code into machine code at once before execution, while interpreter translates and executes the source code line by line.
2. Compiled programs run faster as translation happens only once, while interpreted programs run slower as translation occurs during execution.
3. Compilers generate an intermediate object code file, whereas interpreters don’t produce any intermediate code.
4. Compilers show all errors after compilation, but interpreters stop execution when they encounter an error.
5. Examples of compiled languages: C, C++; Examples of interpreted languages: Python, JavaScript.

Question 3: Explain switching techniques used in computer networks with suitable diagrams. (5 marks) Answer: Switching techniques in computer networks:

1. Circuit Switching:
   • Dedicated communication path established between sender and receiver
   • Path remains reserved until communication ends
   • Three phases: circuit establishment, data transfer, circuit disconnect
   • Example: Traditional telephone networks
   • Advantages: Guaranteed bandwidth, no delay during transfer
   • Disadvantages: Inefficient resource utilization, setup delay
2. Packet Switching:
   • Data divided into packets, each routed independently
   • Two approaches: Virtual Circuit and Datagram
   • Virtual Circuit Packet Switching:
     • Fixed path established for all packets
     • Packets arrive in order
     • Example: Frame Relay
   • Datagram Packet Switching:
     • Each packet routed independently
     • Packets may take different paths
     • May arrive out of order
     • Example: IP networks
   • Advantages: Efficient resource utilization, resilient to failures
   • Disadvantages: Variable delay, potential packet loss
3. Message Switching:
   • Entire message forwarded from node to node
   • Store-and-forward technique
   • No dedicated path established
   • Example: Email systems
   • Advantages: No connection establishment, efficient for non-real-time data
   • Disadvantages: Requires large storage at intermediate nodes, higher delay

The diagrams would show:

• Circuit switching with dedicated path
• Packet switching with packets taking different routes
• Message switching with store-and-forward technique

   • Advantages: More readable than 1GL, still efficient
   • Disadvantages: Still machine-dependent, requires knowledge of hardware
3. Third Generation Language (3GL):
   • High-level procedural languages
   • Machine-independent but problem-oriented
   • Easier to understand and use
   • Examples: C, FORTRAN, COBOL, Pascal
   • Advantages: Portable across platforms, easier programming
   • Disadvantages: Requires compilation/interpretation, less efficient than 2GL
4. Fourth Generation Language (4GL):

Question 1: What is a search engine? (1 mark) Answer: A search engine is a software system designed to search for information on the World Wide Web, indexing websites and providing users with results related to their search queries.

Question 2: Explain the concept of object-oriented programming. (3 marks) Answer: Object-Oriented Programming (OOP) is a programming paradigm based on the concept of “objects” that contain data and code. The key concepts of OOP are:

1. Classes and Objects:
   • Class: A blueprint or template that defines attributes and behaviors
   • Object: An instance of a class with specific values for attributes
2. Encapsulation:
   • Binding data and methods that operate on that data into a single unit
   • Hiding implementation details (data hiding)
   • Access modifiers (private, protected, public) control access to data
3. Inheritance:
   • Mechanism by which a class inherits attributes and behaviors from parent class
   • Promotes code reusability
   • Types: Single, Multiple, Multilevel, Hierarchical
4. Polymorphism:
   • Ability to present the same interface for different underlying forms
   • Method overloading: Same method name with different parameters
   • Method overriding: Redefining methods in derived classes
5. Abstraction:
   • Hiding complex implementation details and showing only essential features
   • Abstract classes and interfaces implement abstraction

Advantages of OOP:

• Modular development
• Code reusability
• Easier maintenance and modification
• Better organization of code

Question 3: Write the algorithm and draw a flowchart to find whether a given number is prime or not. (5 marks) Answer: Algorithm to check if a number is prime:

Step 1: Start
Step 2: Declare variables num, i, flag
Step 3: Read value of num
Step 4: Initialize flag = 0
Step 5: If num <= 1, then
           Set flag = 1
        End If
Step 6: For i = 2 to sqrt(num), do
Step 7:     If num % i == 0, then
                Set flag = 1
                Exit loop
            End If
Step 8: End For
Step 9: If flag == 0, then
            Display "Prime number"
        Else
            Display "Not a prime number"
        End If
Step 10: Stop

Flowchart would show:

• Start symbol
• Input of num
• Decision for num ≤ 1
• Loop for i from 2 to sqrt(num)
• Decision for num % i == 0
• Decision based on flag value
• Output “Prime number” or “Not a prime number”
• Stop symbol

Question 3: Design an algorithm and write a C++ program to check whether a given string is palindrome or not. (5 marks) Answer: Algorithm to check if a string is palindrome:

Step 1: Start
Step 2: Declare variables str, flag
Step 3: Read string str
Step 4: Initialize flag = 0
Step 5: For i = 0 to length(str)/2, do
Step 6:     If str[i] != str[length(str)-i-1], then
                Set flag = 1
                Exit loop
            End If
Step 7: End For
Step 8: If flag == 0, then
            Display "Palindrome"
        Else
            Display "Not a palindrome"
        End If
Step 9: Stop

C++ Program:

#include <iostream>
#include <string>
using namespace std;

int main() {
    string str;
    bool isPalindrome = true;
    
    // Input string from user
    cout << "Enter a string: ";
    getline(cin, str);
    
    // Check if string is palindrome
    int len = str.length();
    for (int i = 0; i < len/2; i++) {
        if (str[i] != str[len-i-1]) {
            isPalindrome = false;
            break;
        }
    }
    
    // Display result
    if (isPalindrome)
        cout << "The string is a palindrome." << endl;
    else
        cout << "The string is not a palindrome." << endl;
    
    return 0;
}
