Answer: TRUE
Explanation: Networking technology is the term used to describe the entire processes through which computer or mobile systems are linked up either through optic fibers,wireless systems in order to enhance effective communication across networks or regions.
OSI (open system interconnection), the earliest models partitions into seven layers and the OSI is known as model that creates partitioning a communication system classing them into abstraction layers.
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.
Answer:
C. While loops run as long as a given boolean condition is true
Explanation:
A while loop will iterate for an indefinite number of times until the specified condition (there is only one) evaluates to false. At which point your loop will stop and execution flow will resume.
The while loop can be illustrated as shown below;
while (condition) { /* do something until condition is false */ }
The moment the condition is false the while loop will break automatically.
Answer:
b. an e-mail
Explanation:
Based on the scenario being described within the question it can be said that the best electronic communication tool in this scenario would be an e-mail. Using e-mails you would be able to send detailed communication messages to all of the individuals that need to read that message in one e-mail. Thus allowing for fast and clear communication between all relevant parties. Both podcasts and Wiki's are used for providing information to clients, or the target audience but not for sharing info within the company.
Answer:
Option B is the correct answer for the above question.
Explanation:
The array is a user-defined data type that is used to define the multiple variables of the same type which can store in the contiguous memory location. If a user wants to define the array then he can do this by the following syntax in c-programming language-- "int a[7];", where a is an array of 7 variables of the integer type which holds the integer data. The 7 is also called the size of the array 'a'. It states that the array named a can hold the 7 integer value. The above -question also asked about the term which defines how much variables an array can hold. The answer is the size of the array which is stated from the option B. Hence B is the correct answer while the other is not because--
- Option A states about the new operator which is not the correct option.
- Option C states about the data type of the array which is not the correct option.
- Option D states about the version of java which is not the correct option.
