Answer:

A. Is the page-replacement algorithm most often implemented.

Explanation:

This algorithm is used when a page that is not present in memory is called, leading to the Operating System to replace one of the existing pages with the needed one. There are different replacing algorithms in order to decide which page will be replaced.

This algorithm is implemented to reduce the number of failures and provide a better funcionality and speed the process by discarding pages that won't be used for a long period of time.

SOVA2 [1]

negatives = []

zeros = []

positives = []

while True:

   number = input("Enter a number: ")

   if number == "":

       break

   else:

       number = int(number)

       if number < 0:

           negatives.append(number)

       elif number == 0:

           zeros.append(number)

       else:

           positives.append(number)

for n in negatives:

   print(n)

for z in zeros:

   print(z)

for p in positives:

   print(p)

Explanation:

Initialize three lists to hold the numbers

Create a while loop that iterates until the user enters a blank line

Inside the loop:

If the number is smaller than 0, put it in the negatives list

If the number is 0, put it in the zeros list

Otherwise, put the number in the negatives list

When the while loop is done, create three for loops to print the numbers inside the lists

Which answer choice correctly distinguishes among the three pieces of data?
wolverine [178]

Answer:

a. 1 is a packet, 2 is data, 3 is a frame.

Explanation:

And what is not  mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer.

Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.

Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
