A student is curious about how a Web site appears on his computer screen. There is a communication between the client and the server in the Application Layer.

Explanation:

When we choose to open a webpage (in any browser) the seventh layer of the OSI model - called Application layer will help to do that.
What happens after we write the webpage address in address bar is that the Application layer protocol (also called HTTP) formats and sends the request from the client's browser (Internet Explorer, Mozilla Firefox , Opera, Safari etc.) to the server.
It also formats and sends the server's respond back to client's browser. This process happens very fast and all the OSI model layers are processing in it (not only the Application layer).
All the layers are working together and each of them is responsible for some particular job, but all together they work as one. The layers communicate with each other and in case of error they will retry and fix the error or if they are unable to do it, the responsible layer will inform the user about the source of the problem.
What happens when page is requested and received? If we will remove the graphical and visual image and look at the process that computer does. We will see a set of commands, mathematical algorithms, symbols, letters and not understandable codes and processes.
When data is sent from "A" to "B", a transport layer is responsible to send and deliver it correctly and exactly the same, what was requested.
If the request, processed by "A" (sender) is too long, the transport layer will divide it in segments (called segmentation process) to understand well and not make a mistake while sending the data to "B" (recipient). After this process data is travelling through the network to the "B" (recipient), if the sent data is segmented or divided, the transport layer is responsible for reassemble it again and "B" (recipient) receives its requested data (It can be web page or other data).
If the transport layer will not do the segmentation process, then the next - network layer - will check the data and if the requested message is too long it will fragment it (called fragmentation process) and will provide the same as transport layer had to do.
All the layers processes are connected to each other and work cooperatively.

Define a function calc_pyramid_volume with parameters base_length, base_width, and pyramid_height, that returns the volume of a

Sever21 [200]

The missing segment of the code illustrates the use of functions.

Functions are also referred to as procedures or methods; they are set of instructions that act as one.

The code segment that complete the code in the question is as follows:

def calc_pyramid_volume(length, width, height):

baseArea = length * width

Volume = baseArea * height * 1/3

return Volume

The first line of the code segment declares the function itself

def calc_pyramid_volume(length, width, height):

Then, the base area of the pyramid is calculated

baseArea = length * width

Then, the volume of the pyramid is calculated

Volume = baseArea * height * 1/3

Lastly, the volume is returned to the main method

return Volume

So, the complete code (without comments) is:

def calc_pyramid_volume(length, width, height):

baseArea = length * width

Volume = baseArea * height * 1/3

return Volume

length = float(input())

width = float(input())

height = float(input())

print('Volume for', length, width, height, "is:", calc_pyramid_volume(length, width, height))
