Answer:
B. False
Explanation:
A page-replacement policy can be defined as a set of algorithm that instructs the operating systems on what memory page is to be swapped, paged out or written to disk in order to allocate more memory as they're required by various active processes during virtual memory management.
Some of the algorithms or techniques used by the operating system for page-replacement policy are;
1. Last In First Out (LIFO).
2. First In First Out (FIFO).
3. Least Recently Used (LRU).
4. Least Frequently Used (LFU).
5. Optimal (OPT or MIN).
Hence, the page-replacement policy means that pages are placed to make more space and to minimize the total number of page that would be missing.
The answer to this question is false.
This is due to the fact that the page-replacement policy helps to decide the pages of memory that needs to be paged out or swapped out.
This becomes necessary at a time when it is necessary for the allocation of a memory page.
It helps the operating system to know the memory space that can be moved out in order to know what space can be made available for the current page.

Python rephactor
1. Write code that swaps the first and last elements in a list called my_list. Assume that the list has already been created and contains at least one element.
2.Write code that creates a Python set containing each unique character in a string named my_string. For example, if the string is 'hello', the set would be {'h', 'e', 'l', 'o'} (in any order). Assign the set to a variable named my_set. Assume that my_string has already been initialized.
1.
my_list = ([1,2,3,4,5])
h = my_list[-1]
my_list[-1] = my_list[0]
my_list[0] = h
print(my_list)
2.
my_string = "hello"
my_set = set(my_string)
print(my_set)
The list has already been created and contains one element. The python set of my string has been already initiated.
What is python set?Python set is defined as a data type for unordered collections that is iterable, changeable, and lacks duplication of elements. There are essentially two sorts of sets in Python. the frozenset and the set. Whether the frozenset is changeable or not depends on the set type. On a set, we can use add(), remove(), and other operations of this nature; however, frozenset does not support these actions.
The program is
your list = ([1,2,3,4,5])
my list[-1] = h
MyList[-1] equals MyList[0]
h print(my list, "my list");
"hello" is my string
set(my string) my set
print(my set)
Thus, the list has already been created and contains one element. The python set of my string has been already initiated.

Write the function which takes an arbitrary real number p , and returns true if the numeber is equals to some power of 2, i.e. p=2n for some n . Your task is to implement a recursive function power_of_2 withount using loops and library functions.
def power_of_2(p):
if p == 2:
return True
elif p < 2:
return False
return power_of_2(p/2)
print(power_of_2(32))
The function keeps dividing the number by 2 until it is equal to 2 or the number ends up being less than 2. If at some point the number is equal to 2, it is a power of 2 otherwise it's not a power of 2.

A server process in Host B has a welcoming socket at port 977. What will trigger the server process to create a connection socket?
Answer:
Explanation:
This connection socket will be created when Host B receives a TCP SYN segment that contains the destination port number 977. This means that there is data that is trying to enter through that port number, as a welcoming socket this destination is available and when data requests access through it the OS creates a connection socket using Host B in order to allow access to the TCP SYN segment.
We wish to produce a graphic that is pleasing and easily readable. Suppose we
make the background color pink. What color text font should we use to make
the text most readable? Justify your answer.Assume that the color Pink is obtained by mixing equal amounts of Red and White. Use the RGB color model and assume that the amount of each primary color in the model is described in the interval [0 255]. Describe the color of the text font you would choose using these conventions.
Answer:
light color
Explanation:
When we will mix equal amounts or equal quantities of the color red and the color white, we will get the color reddish pink. It is popularly called as the SOFT RED and the color code of this color is RGB (255, 128, 128).
Since, red color + white color = 0.5 RGB(255, 0, 0) + 0.5RGB(255, 255, 255)
= RGB (255, 128, 128)
According to me, the color white will best suit as the text color that can be used for a background having RGB(255, 128, 128). Because the color looks more red and not that pink, so it wise to use a light tone color for the natural reading purpose. Hence, it will not give strain to the eyes.
Some of the arguments are valid, whereas others exhibit the converse or the inverse error. Use symbols to write the logical form of each argument. If the argument is valid, identify the rule of inference that guarantees its validity. Otherwise, state whether the converse or the inverse error is made. If this computer program is correct, then it produces the correct output when run with the test data my teacher gave me. This computer program produces the correct output when run with the test data my teacher gave me.
∴
This computer program is correct.
Let p = "this computer program is correct," and let q = "this computer program produces the correct output when run with the test data my teacher gave me." Is the argument valid or invalid? Select the answer that shows the symbolic form of the argument and justifies your conclusion.
Hi, you've asked an incomplete/unclear question. I inferred you want a symbolic representation and validity of the argument mentioned.
Answer:
argument is valid
Explanation:
Let's break down the arguments into parts:
Let,
p = "if this computer program is correct,"
q = "this computer program produces the correct output when run with the test data my teacher gave me."
c = "This computer program is correct."
Meaning, p ⇒ q (p results in q), then we can conclude that,
(p ⇒ q ) ∴ ⇒ c
However, the correct converse of the statement is:
If this computer program produces the correct output when run with the test data my teacher gave me, then the computer program is correct,"
q ⇒ p (If q then p)
While the correct inverse of the statement is:
If this computer program is not correct, then this computer program does not produce the correct output when run with the test data my teacher gave me."

Consider a distributed denial of service (DDOS) attack, Assume the attacker has compromised a number of broadband connected computers to use as zombie systems. If the ISP provides a maximum uplink data rate of 512 Kbps in ADSL, what is the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second? How many such zombie systems would the attacker need to flood a target server in an organization that has
a. A Fast Ethernet.
b. A Gigabit Ethernet.
Answer:
A ) 200 Zombie systems
B ) 200 Zombie systems
Explanation:
maximum uplink data rate : 512 kbps = 512 * 1000 * 8 = 4096000 bits/sec
Determine the number of 512 byte ICMP echo packets = 512 * 8 = 4096 bits
hence the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second = 400 packets/sec
i.e. for 512kbps = 400 packets/sec
Determine the number of Zombie systems that the attacker will need to flood a target server
A) For a fast ethernet
A fast ethernet = 100 mbps
The number of Zombie systems needed = 1 zombie system * 200
and 1 zombie system = 512 kbps
therefore for a Fast ethernet the number of zombies systems needed = 200
B) For A Gigabit Ethernet
same as a fast ethernet system i.e. = 200

If process P0 is switched to process P1, state for P0 will be saved into ____, and state from ___ will be reloaded.
Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.

A new version of your operating system is released with several changes made to the transport layer protocols. Specifically, TCP has been removed completely but UDP was not changed. What specific changes must be made to your application to accomodate these changes?
Answer:
Throughout the description section down, the overview and per the instance.
Explanation:
Throughout terms of communicating and maintaining a link between the application as well as the network, TCP protocols were essential. The program would not be linked or activated if the TCP has indeed been fully disabled. The essential TCP protocol that enables the application to be linked from over network become HTTP as well as HTTPS. Almost all of the significant protocols needed to operate some programs are based primarily on TCP protocols. Besides, as SSH would not operate as a TCP protocol, the OS would not be remotely linked.Therefore, that would also make it impossible for all the administrators to operate upon this system.

Write in Java:
Given a long integer representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212.
Ex: If the input is:
8005551212
the output is:
(800) 555-1212
Hint: Use % to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which is 72.
Hint: Use / to shift right by the desired amount. Ex: Shifting 572 right by 2 digits is done by 572 / 100, which yields 5. (Recall integer division discards the fraction).
For simplicity, assume any part starts with a non-zero digit. So 0119998888 is not allowed.

A user creates a GPO. What do you need to do for that user to manage his or her GPO that he or she created?
Answer: Nothing should be done.
Explanation:
Group Policy helps in the provision of a centralized management of operating systems, and applications. It should be noted that a group policy object (GPO) is simply referred to as the configurations involving the group policy.
Nothing should be done to manage the GPO created. When the permission to create a GPO has been given to someone, it means that they can also manage the GPO therefore, nothing needs to be done anymore.

The four smallest numbers (40 points) Write an ANNA assembly program (smallest_four.ac) that finds the four smallest numbers entered by the user. Initially, the program continually asks the user to enter numbers. As soon as a negative value is entered, compute which numbers are the top four (smallest) numbers. For instance, if the user entered 2, 6, 7, 6, 5, 7, 6, 17, 15 -1; the program should print 2, 5, 6, 6 (the four smallest numbers in the sequence). If the user enters a negative number at the beginning, print 0. If the user enters four or fewer numbers, print all the numbers as output.
Notes:
• The goal of this problem is to exercise storing, retrieving, and scanning the numbers stored in memory. Therefore, a solution where you keep track of the smallest four numbers in registers as the numbers are entered is not acceptable. Such a solution will receive a maximum of 15 points for this problem.
• Do not keep track of everything in the input loop. You will need to store all numbers entered by the user in memory.
• Store all numbers entered into a growing array. • Note that The array should be the last item in your data section so it can grow as large as necessary.
• You may assume there is enough memory to hold all numbers entered by the user.
