What resistance R3 in parallel with resistances R1=10K Ω and R2=20K Ω gives an
equivalent resistance of Req=50 Ω

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.

Here are the "superpowers" we gain through advancing media and information:

• Access to vast amounts of knowledge. We have the world's information at our fingertips through the internet. This allows us to continually learn and expand our minds.

• Ability to spread ideas quickly. Media allows us to share knowledge, opinions, concepts, and more with a wide audience instantly. This can help spread innovations, raise awareness for important causes, and shape public discourse rapidly.

• Connecting across distances. We can connect with people all over the globe through services like video calling, social media, messaging, and more. This allows us to build relationships and collaborate with a diverse range of people.

• Aggregating and summarizing information. Media helps filter through massive amounts of information and condense it into more consumable content like news highlights, documentaries, courses, tutorials, best-of lists, etc. This helps us stay informed efficiently.

• Providing alternative perspectives. Exposure to a diversity of media exposes us to different perspectives and opinions. This helps promote openness, combat filter bubbles, and make us more well-rounded and empathetic individuals.

• Enabling productivity and convenience. Technologies like smart assistants, cloud services, streaming media, mobile apps, and more help simplify our lives and optimize our time. We can accomplish more while having greater convenience and flexibility.

• Connecting interests and communities. Platforms are built to bring together people with common interests, hobbies, locations, identities, experiences and more. This allows niche communities to form, collaborate, and strengthen bonds.

• Distributing and promoting creative works. It is easier than ever for individuals to create and share their creative works with a wide audience. This democratization of media allows more voices to be heard and more stories to be told.

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!".

In a balanced budget, the Income amount is same as the expense amount.

A balanced budget is one in which the revenues match the expenditures. As a result, neither a fiscal deficit nor a fiscal surplus exist. In general, it is a budget that does not have a budget deficit but may have a budget surplus.

Planning a balanced budget assists governments in avoiding excessive spending and focuses cash on regions and services that are most in need.

Hence the above statement is correct.
