Answer:
Network infrastructure for internet.
Roshan Mandal
Designing an infrastructure for a network that is connected to the internet involves several components and steps. The first step is to establish an internet connection through an Internet Service Provider (ISP). The ISP will provide a modem or router that connects to the internet and translates the data between the local network and the internet.
The local network should consist of several components, including computers, printers, and servers. These devices can be connected through wired or wireless connections, depending on the infrastructure of the local network.
To provide access for users, the network must have user authentication and authorization mechanisms. These mechanisms ensure that only authorized users can access the network and its resources. This can be achieved through the use of usernames and passwords, access control lists, or biometric authentication.
When a photo, text, or email is sent from one device to another device on the internet, it goes through several stages. The sender's device first sends the data to the local network's router or gateway. The router then forwards the data to the ISP's network, which then sends the data to the recipient's ISP.
The recipient's ISP then sends the data to the recipient's router or gateway, which then sends the data to the recipient's device. The entire process of transmitting data from one device to another device on the internet occurs within a few seconds and involves several network components and infrastructure.
In conclusion, designing an infrastructure for a network that is connected to the internet involves several components and steps. Providing access for users and ensuring the security of the network are critical components of the infrastructure. When data is transmitted from one device to another device on the internet, it goes through several stages and involves multiple network components.

explain the structure of c program with example
Answer:
A C program typically consists of a number of components, including preprocessor directives, function prototypes, global variables, functions, and a main function.
Explanation:
Here's an explanation of each component, followed by an example C program that demonstrates their usage:
Preprocessor Directives: Preprocessor directives are instructions to the C preprocessor, which processes the source code before compilation. They usually start with a '#' symbol. Some common directives are #include for including header files and #define for defining constants.
Function Prototypes: Function prototypes provide a declaration of functions that will be used in the program. They specify the function's name, return type, and the types of its parameters.
Global Variables: Global variables are variables that can be accessed by any function in the program. They are usually defined outside of any function.
Functions: Functions are blocks of code that can be called by name to perform specific tasks. They can accept input parameters and return a value. Functions are generally declared before the main function.
Main Function: The main function is the entry point of the program. It's where the execution starts and ends. It has a return type of int and typically takes command-line arguments via two parameters: argc (argument count) and argv (argument vector).
Here's an example C program that demonstrates the structure:
// Preprocessor directives
#include <stdio.h>
// Function prototypes
void print_hello_world(void);
// Global variable
int global_var = 10;
// Functions
void print_hello_world(void) {
printf("Hello, World!\n");
}
// Main function
int main(int argc, char *argv[]) {
// Local variable
int local_var = 20;
printf("Global variable value: %d\n", global_var);
printf("Local variable value: %d\n", local_var);
print_hello_world();
return 0;
}
This simple C program demonstrates the use of preprocessor directives, a function prototype, a global variable, a function, and the main function. When run, it prints the values of a global and a local variable, followed by "Hello, World!".

Write a program that takes an integer list as input and sorts the list into descending order using selection sort. The program should use nested loops and output the list after each iteration of the outer loop, thus outputting the list N-1 times (where N is the size of the list).
Important Coding Guidelines:
Use comments, and whitespaces around operators and assignments.
Use line breaks and indent your code.
Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code.
Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable.
Ex: If the input is:
20 10 30 40
the output is:
[40, 10, 30, 20]
[40, 30, 10, 20]
[40, 30, 20, 10]
Ex: If the input is:

[8, 7, 3]
Note: Use print(numbers) to output the list numbers and achieve the format shown in the example.
Answer:
Here's a program that implements the requested selection sort in descending order with the specified guidelines:
def selection_sort_descending(numbers):
# Iterate through the list
for i in range(len(numbers) - 1):
max_index = i
# Find the index of the maximum element in the remaining unsorted part of the list
for j in range(i + 1, len(numbers)):
if numbers[j] > numbers[max_index]:
max_index = j
# Swap the maximum element with the current element
numbers[i], numbers[max_index] = numbers[max_index], numbers[i]
# Print the list after each iteration
print(numbers)
# Example usage
input_list = [20, 10, 30, 40]
selection_sort_descending(input_list)
# Another example usage
input_list2 = [7, 8, 3]
selection_sort_descending(input_list2)
Explanation:
This program takes a list of integers and sorts it in descending order using the selection sort algorithm. It also outputs the list after each iteration of the outer loop, as requested.
