"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:

brand community

Explanation:

Many company websites are now designed to do more than just sell a product. These websites, known as brand community websites, attempt to build closer customer relationships and generate engagement with and between the brand and its customers. These online communities bring together consumers who have shared interests in a brand or product. One advantage of online brand communities is that they reduce customer support costs as the business has more engagement with their customers.This also helps the business to retain customers through brand improvement centered around the customer's actual needs.

Explain how you would assess the operating system requirements for virtualization if the organization wanted to virtualize 25% o

insens350 [35]

Answer:

The requirement of the virtualization in the operating system:

• The virtualization of the resources from single systems input can be partitioned into a small virtual environment in multiple system data processes.

• Virtualization can collect the physical system's hardware and software data, they can transfer the virtualization process and also verify that the working system is running properly.

• Virtualization has to determine the specific components such as workload, file location, network traffic and console administration process. The requirement for moving into the virtual environment must be selected based on windows for the operating system(32-bit), windows host operating system(4-bit) and Linux operating system.
