If you want to add a new row in Microsoft Excel, you need to use the Insert Row function. However, if you want your row to be placed between two existing rows, the option you should choose is (C) Right-click row 21's row number, and then click Insert. If you right-click on row 20 instead, the new row would appear between row 19 and 20.

What additive keeps engines clean by preventing contaminates and deposits from collecting on surfaces? a. Friction modifiers b.

White raven [17]

Answer is: Dispersants

Explanation:

Dispersants keep contaminants (e.g. soot) suspended in the oil to prevent them from coagulating. Anti-foam agents inhibit the production of air bubbles and foam in the oil which can cause a loss of lubrication, pitting, and corrosion where entrained air and combustion gases contact metal surfaces.

So that's why the answer is: Dispersants

"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.

The project manager of a software development team needs to hire someone to review every part of the software to make sure it wo

Zielflug [23.3K]

Answer:

code reviewer

Explanation:

In this scenario, the project manager should advertise for a code reviewer. Usually a development team has at least 2 code reviewers that are very familiar with the code that is being written for the project. Once sections of code have been completed it is usually the case that both the project lead and a code reviewer both review the entire software to look for bugs and note improvements that can be made to make the code more efficient.
