The time that is required to retrieve the object (including TCP connection establishment) when [tex]4S/R > S/R > RTT > 2S/R[/tex] is equal to [tex]\frac{14S}{R}+4RTT[/tex]
How to calculate the time needed to receive all objects.In this scenario, we would denote the round-trip time that exist between the web server and the client with [tex]RTT[/tex] and assume that it is constant.
The time that is required to retrieve the object when [tex]4S/R > S/R > RTT > 2S/R[/tex] would be calculated by adding the round trip of sender and reciever together as follows:
Round trip = RTT + RTT
Next, we would determine the delay in packet transmission:
Note: [tex]\frac{8S}{R}+\frac{4S}{R}=\frac{12S}{R}[/tex]
[tex]Time = (\frac{S}{R} +RTT)+(\frac{S}{R} +RTT)+(\frac{12S}{R}) +RTT+RTT\\\\Time = \frac{14S}{R}+4RTT[/tex]
When [tex]S/R +RTT > 4S/R[/tex], we have:
The time that is required to retrieve the object would be calculated by adding the round trip of sender and reciever together as follows:
[tex]Time = (\frac{S}{R} +RTT)+(\frac{S}{R} +RTT)+(\frac{8S}{R}) +RTT+RTT\\\\Time = \frac{11S}{R}+5RTT[/tex]
The time that is required to retrieve the object when [tex]S/R > RTT[/tex] would be calculated by adding the round trip of sender and reciever together as follows:
[tex]Time = (\frac{S}{R} +RTT)+(\frac{14S}{R}) +RTT\\\\Time = \frac{15S}{R}+3RTT[/tex]

A team of computer science researchers develop a program for searching trees that can be run in parallel. When they use distributed computing techniques to run the program on six computers in parallel, they find a speedup of 3. In this case, what does a speedup of 3 indicate?
Answer:
The program completed in a third of the time with six computers versus one computer.
Explanation:
The speedup of a parallel solution is measured in the time it took to complete the task sequentially divided by the time it took to complete the task when done in parallel (or put succinctly, speedup = sequential/parallel).A speedup of 3 means that the program took three times as long on one computer, which is the same thing as saying it took a third of the time with all six computers working in parallel.

First, write a printArray() function that prints out the array. Use a single parameter in the definition of the function, and pass the array you created above as the parameter. Call the function so it prints the original array.
Then write a flipHorizontal() function that flips the contents of the array horizontally and prints the result. This means that the values in each row should be reversed (look at the second array in the sample run of the program for clarity). Again, this function should pass the original array as the parameter. Within your flipHorizontal() function, call the printArray() function to print the new array that has been horizontally flipped.
Reset the array back to the original 5 x 5 array we started with.
Then write a flipVertical() function that flips the contents of the array vertically and prints the result. This means that the values in each column should be reversed (look at the third array in the sample run of the program for clarity). Again, this function should pass the original array as the parameter. Within your flipVertical() function, call the printArray() function to print the new array that has been vertically flipped.
The sample run below shows how your code should print the original array, followed by the horizontally-flipped array, followed by the vertically-flipped array. Notice that the output below includes blank lines between each of the three arrays - yours should do the same.

04. Suppose a computer program needs to sort a list of student records in ascending order
according to last name. The program language determines sort order by using the
individual ASCII number representations of the characters in each name.
If the initial list contains the following names. Which of the following lists represents
the name order after executing the sorting procedure?
["Tom Smith","Joe Schnook", "Kathy Bones","Jill Brewer"]
(A) ["Smith Tom", "Schnook Joe","Bones Kathy","Brewer Jill"]
(B) ["Joe Schnook","Tom Smith","Jill Brewer", "Kathy Bones"]
(C) ["Jill Brewer","Joe Schnook", "Kathy Bones", "Tom Smith")
(D) ["Kathy Bones","Jill Brewer","Joe Schnook","Tom Smith"]
Answer:
D) ["Kathy Bones", "Jill Brewer", "Joe Schnook", "Tom Smith"]
Explanation:
The context of the problem explains a computer program that sorts names in "ascending order" (A to Z) since the ASCII table has capital A start a lower number and it increases from there to capital Z.
Notice how the attached file, which is a portion of the ASCII table, shows that letters after A are also higher in decimal value than the previous letter.
With this in mind, we know that all this program does is sort by last name alphabetical order. From there, just sort the given names using that same criteria, last name alphabetical order, and the correct answer is determined.
Please put "Brainliest" on my answer if it helped you out!
If you want to learn more about this subject, you can search:
- ASCII Table
- Lists in Programming
- Sorting Procedures
The correct list that represents the name order after executing the sorting procedure is (D) ["Kathy Bones", "Jill Brewer", "Joe Schnook"," Tom Smith"]. Therefore, option D is correct.
What is a computer program?A computer program is a set of instructions that tells a computer what to do to perform a specific task or solve a problem.
Since the program sorts the names in ascending order according to last name, it will consider the last name first and then sort the names alphabetically based on the ASCII value of the characters in each last name.
So, in the initial list, "Bones" comes before "Brewer", which comes before "Schnook", which comes before "Smith". Therefore, after sorting, the correct order of the names would be: "Kathy Bones", "Jill Brewer", "Joe Schnook", and "Tom Smith". Thus, option D is correct.
