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.
Explanation:
The ndarray (NumPy Array) is a multidimensional array used to store values of same datatype. These arrays are indexed just like Sequences, starts with zero.
Answer:
B.
Explanation:
Based on the sampling methods provided in regards to the question it can be said that the method being used is called Simple Random. This refers to dividing the population into different group which are then chosen at random, giving each group an equal chance of getting chosen. Which is exactly what is going on in this scenario, as the day is divided into three parts and her mood is measured randomly during each part of the day.
Answer:
contractor management outsourcing
Explanation:
For any recruiter, two things are important. They want to ensure more time, and hence more money. By the time I mean, they want to avoid investing time in something that does not generate revenues. And unfortunately, there exists a bundle of such irrelevant, and yet must-do activities which we need to perform. However, if we opt for contractor management outsourcing to a better management employment relationship, we save a lot of time and earn more as a recruiter. However, we then spend more time creating a contract, as even a single faulty clause can be hard for you to engulf in the future. And that is why it requires more time. However, the good part is, we as a recruiter are happy by the end of the day, as we earn more profit. And it's due to better resource and time management.
