Suppose P, Q and R are ISPs with respective CIDR address blocks (with bytes in decimal) 51.0.0.0/8, 52.0.0.0/8 and 53.0.0.0/8. P then has customers A and B, to which it assigns address blocks as follows:
A: 51.10.0.0/16
B: 51.23.0.0/16
C: 52.14.0.0/16
D: 52.15.0.0/16
Q has customers C and D and assigns them address blocks as follows:(a).♢ Give forwarding tables for P, Q and R assuming they connect to each other and to each of their own customers.
(b). Now suppose A switches from provider P to provider Q, and takes its address block with it. Give the changes to the forwarding tables for P, Q and R; the longest-match rule will be needed to resolve conflicts.

Address blocks as 52.14.0.0/16, IP addresses come in static and dynamic varieties .The words IPv4 and IPv6 refer to Internet Protocol versions 4 and 6, respectively.
To whom are IP address blocks assigned?The Internet Assigned Numbers Authority (IANA) and five regional Internet registries (RIRs) are in charge of managing the IP address space on a global scale and are in charge of assigning IP addresses to local Internet registries, such as Internet service providers (ISPs) and other end users, in their respective regions.IP addresses come in static and dynamic varieties.The words IPv4 and IPv6 refer to Internet Protocol versions 4 and 6, respectively. IPv6 is the newest version of Internet Protocol and is far more efficient and sophisticated than IPv4. Difference IPv4 and IPv6 are the two options.

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done, report to the user the position of the first 7 entered and the last 7 entered. By position we mean, for example, that if the first 7 is the 2nd number entered then its position would be 2.
Answers
Answer:
The program written in Python 3 is as follows;
The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program
num = int(input("Number of Inputs: "))
mylist = []
userinput = int(input("Enter a digit: "))
i = 1
while i < num:
mylist.append(userinput)
userinput = int(input("Enter a digit: "))
i += 1
try:
first7 = mylist.index(7)+1
print('The first position of 7 is ',first7)
last7 = num - 1 - mylist[::-1].index(7)
print('The last position of 7 is ',last7)
except:
print('7 is not on the list')
Explanation:
This line prompts user for the number of inputs
num = int(input("Number of Inputs: "))
This line declares an empty list
mylist = []
This line inputs the first number into the empty list
userinput = int(input("Enter a digit: "))
The italicized lines represent an iteration that allows user to input the numbers into the empty list.
i = 1
while i < num:
mylist.append(userinput)
userinput = int(input("Enter a digit: "))
i += 1
The try-except is used to check the presence of 7 in the list
try:
This checks the first occurrence of 7
first7 = mylist.index(7)+1
This prints the first occurrence of 7
print('The first position of 7 is ',first7)
This checks the last occurrence of 7
last7 = num - 1 - mylist[::-1].index(7)
This prints the last occurrence of 7
print('The last position of 7 is ',last7)
The following is executed if there's no occurrence of 7
except:
print('7 is not on the list')

And office now has a total of 35 employees 11 were added last year the year prior there was a 500% increase in staff how many staff members were in the office before the increase
Answers
There were 5 staff members in the office before the increase.
To find the number of staff members in the office before the increase, we can work backward from the given information.
Let's start with the current total of 35 employees. It is stated that 11 employees were added last year.
Therefore, if we subtract 11 from the current total, we can determine the number of employees before the addition: 35 - 11 = 24.
Moving on to the information about the year prior, it states that there was a 500% increase in staff.
To calculate this, we need to find the original number of employees and then determine what 500% of that number is.
Let's assume the original number of employees before the increase was x.
If we had a 500% increase, it means the number of employees multiplied by 5. So, we can write the equation:
5 * x = 24
Dividing both sides of the equation by 5, we find:
x = 24 / 5 = 4.8
However, the number of employees cannot be a fraction or a decimal, so we round it to the nearest whole number.
Thus, before the increase, there were 5 employees in the office.

You work at a print shop that produces marketing materials, and your manager asks you to install a new printer. The printer comes with two options for drivers. One uses PCL, and the other uses Postscript. Which driver is the best option and why
Answers
Since you work at a print shop that produces marketing materials, and your manager asks you to install a new printer. The drivers that is best is PCL, because it can be used in the office to print physical document while the Postcript can only be used for online document or pdf and since it is office job, PCL is the best.
What is PCL printer?PCL use depends on the device. This indicates that certain printed data, typically graphical data like fill areas, underlines, or fonts, is created by the drivers for this language by using the printer hardware. As a result, the print job can be processed by the computer fast and effectively. The production and processing of page data must then be finished by the printer.
Note that If you typically print from "Office" programs in general, use the PCL driver. If you wish to print PDFs more quickly or use professional DTP and graphics tools for the majority of your printing, pick the PostScript driver.

D. Creating a directory of which computers have certain files is an acceptable practice.
Answers
Answer:
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
Explanation:
CORRECT
Choice 'A' is very true. There have been many arguments and court cases over what content can and cannot be shared through a peer-to-peer network. Users of these networks often argue that free speech allows us to share whatever we want online. Content creators on the other hand frequently sue for copyright infringement.
INCORRECT
Choice 'B' is describing a centralized system, not a peer-to-peer network. In a peer-to-peer network, there is no central location of files. Files are transferred directly from one computer to another without a middleman.
Choice 'C' is also not true of peer-to-peer networks. These networks are actually much more efficient than centralized systems because there is no large server holding all the files. It takes less time to download files from a peer-to-peer network because there is no centralized source of information and files.
Choice 'D' is also false; this was decided in the court case about Napster, one of the first large peer-to-peer networks. Having a centralized directory of who has which files is not considered free speech.
The peer-to-peer network is said to have varying views that form the basis of what can and cannot be shared. Thus, option A is correct.
What is a peer-to-peer network?A peer-to-peer network is given as the connection of the computers that are linked with the following same responsibilities and permissions.
