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.
The statement above wil be completed.
For some people, alcohol can cause an uncontrollable vibration to the eyes, making good vision almost impossible. This vibration is called nystagmus or the eyes getting dizzy and shaky. This nystagmus occurs when a person drinks too much and reaches his limit in alcohol intake.
Answer:
O(n) which is a linear space complexity
Explanation:
Space complexity is the amount of memory space needed for a program code to be executed and return results. Space complexity depends on the input space and the auxiliary space used by the algorithm.
The list or array is an integer array of 'n' items, with the memory size 4*n, which is the memory size of an integer multiplied by the number of items in the list. The listSize, i, and arithmeticSum are all integers, the memory space is 4(3) = 12. The return statement passes the content of the arithmetic variable to another variable of space 4.
The total space complexity of the algorithm is "4n + 16" which is a linear space complexity.
