Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bill needs to send a document across a network to Ben. Write an algorithm to show how packets are used to send the document, starting from when Bill clicks send (sending), and finishing when Ben reads the document (receiving).Which algorithm best represents sending a packet?
A
Bill’s computer splits data into equal sizes packets (1)Each packet is given the address of Ben’s computer (1)Each packet is given a number (1)Each packet is given error checking data (1)The packets are sent across the network (1)
B
Ben’s computer checks if all packets have been received? (1)If No____Check again (1)____Increment timer (1)____If timer > max wait (1)____Send timeout to Bill’s computer (1)If Yes____Reorder packets based on their number (1)____Display the document (1)____Send receipt confirmation (1)____Each packet is checked for errors(1)____ if corrupt a message is sent back to sender (1)
C
Bill’s computer splits data into different sizes packets (1)Each packet is given the address of Ben’s computer (1)Each packet is given a with a zero (1)Each packet is given erroneous data data (1)The packets are sent across the network (1)
D
Ben’s computer checks if all packets have been received? (1)If Yes____Check again (1)____Increment timer (1)____If timer > max wait (1)____Send timeout to Bill’s computer (1)If No____Reorder packets based on their number (1)____Display the document (1)____Send receipt confirmation (1)____Each packet is checked for errors(1)____ if corrupt a message is sent back to sender (1)
Explanation: 

Detailed explanation-1: -The webserver is the device that stores the webpage data. The client is the computer that requested the web page. When clicking a hyperlink, the client sends a request to the webserver. The webserver processes the request and prepares the webpage.

Detailed explanation-2: -An analogue-to-digital converter will capture a sound wave at regular time intervals. This recording is known as a sample . This data is then stored in a file for later use.

Detailed explanation-3: -A fragmented disk takes longer to read from and write to, making a computer run slower. Defragmentation software takes the fragmented files and rearranges the segments so that they run contiguously. This decreases read/write time, thereby speeding up computer performance.
