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.

in america we are free to say most of whatever we want in media becuase we have free speech here. in other countries, they don't have freedom of speech,and sometimes it also has to do with the political situation. like say in china, where teenagers arent allowed to use the internet for more than a certain amount of time,and arent allowed to talk to each other. thats becuase of the fact that that country is a communist country and the government wants much more control than in other countries.
Answer:
Costs will cover a need for more customer data. The further explanation is given below.
Explanation:
- It's the greatest problem for almost every company to provide the data with security.
- This is possible for highly trained practitioners and the technical staff to take charge of it.
- Complicated technologies would have been going to run together again to withstand these types of jobs.
- Such problems play a major part in the decision-making process affecting the law enforcement authorities to locate the suspects to strengthen the organization.
- To do something like this, there seem to be a lot of other good initiatives out there doing it.
There have been some cases in which major corporations have chosen not to include law enforcement:
- There are many more electronic corruption going on, including money robbery, asset fraud, as well as machine assaults.
- In such a bigger case, numerous institutions, such as large-scale ones, have gone through these circumstances to evaluate law enforcement to come to terms with cybersecurity.
