"Explain the functionality of the different layers found in the network protocol stack of an operating system such as Linux"

arsen [322]

Answer:

There are 7 layers in linux.

Explanation:

As networking is difficult and complex.

Imagine if every application had to know how to communicate on every step that would be more than just complex. So, rather than reinvent something which will help it to communicate let’s just make something that will automatically controls the communication and for that protocols came in to live.

As for the linux operating system, it is not exceptional from other operating systems.

There are 7 layers on network protocol stack use to communicate with other network protocol stack.

1. Application layer

2. System call interface

3. Protocol agnostic interface

4. Network protocol

5. Device agnostic interface

6. Device drivers

7. Physical hardware

All the layers vary in their functionality.

One more important thing to remember is that the network protocol stack layers is not one way its 2 way communication. First, when a client request to a network and second, when the request is full filled.

The top most layer is a part of user space, the next five layers comes in the kernel space and the final layer is the physical layer.

Application layer:

When a client or user request to a network the request initially comes to this layer.

On this layer we use tcp/ip protocol.

System call interface(SCI):

When application layer make a call to the kernel this layer handles that call. And take the request to the next layer.

Protocol agnostic interface:

This layer has two functions “talking” or “listening”. There is a thing called sockets which perform these functions and each socket has an id which is used specifically for an application.

Network protocol:

This layer is used for how the data is sent or received.

Device agnostic interface:

It is used to connect data from/to kernel user space and the network device drivers which allows the data to prepare itself for transmission over the medium from the network device.

Physical hardware :

This layer is responsible for the data packets transmission and received from the network medium being used whether cable or wireless.

Answer:

Brainliest

Explanation:

It’s hard to imagine banks without technology. In fact, computers have been in use in banking since the 1950s, when Bank of America introduced a computer designed specifically for processing checks. Each new decade has brought innovations that change the way banks manage daily operations and serve customers. Today, you may not even leave your house to do your banking. As much as technology has changed the use of the computer in the banking sector, banks continue to adjust the way they do things.

Lerok [7]

Answer:

See the code below and the algorithm explanation on the figure.

Explanation:

The explanation in order to get the answer is given on the figure below.

Solving this problem with C. The program is given below:

#include <stdio.h>

int main(void) {

int n, Even=0, Odd=0, Zeros=0;

for (;;) {

printf("\nEnter the value the value that you want to check(remember just integers): ");

//IF we input a non-numeric character the code end;

if (scanf("%d", &n) != 1) break;

if (n == 0) {

Zeros++;

}

else {

if (n % 2) {

Even++;

}

else {

Odd++;

}

printf("for this case we have %d even, %d odd, and %d zero values.", Even, Odd, Zeros);

return 0;

}
