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?
|
|
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)
|
|
|
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)

Explanation:
Detailed explanation-1: -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.
