The page-replacement policy means that pages are not placed to make more space. A. True B. False

Answers

Answer 1

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.

Answer 2

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.

you are packing a mobile phone containing a lithium ion battery and you get a prompt on the screen to put a lithium ion label on the box. You have run out of such labels and have only lithium metal labels left. what should you do?

Answers

Answer:

Do not use such labels because they may be misleading and are unethical.

Explanation:

Note, there is a big difference in design between the two terms or labels. Lithium metal batteries are non-rechargeable batteries. In other words, they cannot be recharged after they run down. For example, most watches, calculators, or car keys are made of lithium metal batteries.

While Lithium-ion batteries (or Li-ion batteries) are rechargeable batteries , and they are commonly used by mobile phones, laptops, and other gadgets.

Therefore, with such differences in mind, it may be very misleading when someone in possession of the mobile phone sees the lithium metal labels; then thinks the battery is non-rechargeable.

There are different instructions that comes with labeling, lithium metal label  is quite different from Lithium-ion labels and as such one cannot use one for the order.

What one should you do is to never use the lithium metal labels in place of  Lithium-ion labels. It is better to go and get the required label. If not found, the mobile phone should not be packaged for transport.

One has to comply with the regulations regarding batteries and the packaging of lithium batteries.

Lithium Metal Batteries  are known as primary battery. That is, they are non-rechargeable. They are said to have lithium metal or lithium compounds in them.

They have high energy density than other lithium batteries.   They can be found in Watches , Calculators etc.

Lithium-ion batteries are known to be  secondary battery. That is, they are said to be rechargeable in nature. They can be found  in Mobile phones, Laptops etc.

When shipped, any packages that has lithium-ion batteries must be labeled with  UN3480  or UN3481.

When shipped, any packages that has lithium metal batteries must be labeled  with UN3090  or UN3091.

The string expression strVar.____________________ starts at index pos, replaces the next n characters of strVar with all the characters of str.

Answers

Answer:

strVar.replace(pos, n, str);

Explanation:

The strVar.replace() is a javascript function of searching and replacing a string for a defined value, whereby it finds and returns a new string where the defined values are replaced.

For example: to return a string where "Trump" is replaced with "Biden":

We have

var str = "Welcome Trump!";

Your personal opinion about what a "successful" console in the future will need to include to sell well. How have the changes in technology, gaming culture, and overall society affected the market?

Answers

Answer:

The answer is below

Explanation:

In my personal opinion what a "successful" console in the future will need to include to sell well is "a big library of games." This feature will help a console supports many games that will appeal to all categories of gamers.

The changes in technology, gaming culture, and overall society has affected the game market in many ways such as:

1. In terms of technology: it has made the game manufacturers both the console and third-party game developers to improve their gaming features. For example, the advancement in gaming pads becoming wireless. The gaming console having internet or online features, where gamers can play with each other around the world from their rooms. Also, the gaming character design looking more and more like the real-life personality it represents.

2. In terms of gaming culture: modern games are no longer for teenagers alone. It is now appealing to adults as well. This is evident in football players and coaches playing the games and talking about it. Even some players tend to influence their ratings in the game by mentioning how good they are in the press in comparison to the rating game developers are giving them.

3. Overall society has now seen gaming consoles as part of everyday life. The parents, researchers, and even feminist groups are now well aware of the gaming industry. And each of the stakeholders involved is influenced by how the game consoles manufacturers market their games through media, sports personalities, celebrities, etc.

Explanation:

I took the test

If an app asks for a user's age, it may be because the app requires a user to be over a certain age to use some of the services it provides. Write a function called checkAge that takes one parameter of type String. The function should try to convert this parameter into an Int value and then check if the user is over 18 years old. If he/she is old enough, print "Welcome!", otherwise print "Sorry, but you aren't old enough to use our app." If the String parameter cannot be converted into an Int value, print "Sorry, something went wrong. Can you please re-enter your age?" Call the function and pass in userInputAge below as the single parameter. Then call the function and pass in a string that can be converted to an integer.
Go back and update your function to return the age as an integer. Will your function always return a value? Make sure your return type accurately reflects this. Call the function and print the return value.
func checkage(age: String)->Int?
{
if let age_type = Int(age)
{
if age_type > 18 {
return "Welcome!"
}
else if age_type < 18 {
return"Sorry, but you aren't old enough to use our app."
}
}
else {
return "Sorry, something went wrong. Can you please re-enter your age?"
}
return age_type
}

Answers

Answer and Explanation:

Here the programming language swift is being used. There is a slight error in the program shown above:

var userInputAge=9

func checkage(age: String)->int?

{

if let age_type = Int(age)

{

if age_type > 18 {

return "Welcome!"

}

else if age_type < 18 {

return"Sorry, but you aren't old enough to use our app."

}

}

else {

return "Sorry, something went wrong. Can you please re-enter your age?"

}

return age_type

}

The program should be revised :

func checkage(age: int?)->String

{

if let age_type = Int(age)

{

if age_type > 18 {

return "Welcome!"

}

else if age_type < 18 {

return"Sorry, but you aren't old enough to use our app."

}

}

else {

return "Sorry, something went wrong. Can you please re-enter your age?"

}

return age_type

}

We call the functions :

checkage(userInputAge)

checkage("15")

Note: we revised the program for errors in the first line of the code where the int optional parameter(int?) was supposed to be used instead of the String parameter in the function. We then called the function using the userInputAge variable defined as the parameter and then we now also used a String as the parameter for calling the function the second time.

Answer:

def checkage(age: "String")->int:

   if age >= 18:

       return "Welcome!"

   return "Sorry, but you aren't old enough to use our app."

   

for _ in iter(list,0):

   myage = int(input("Please enter your age: "))

   if myage is int(myage):

       result = checkage(myage)

       print(result)

       break

   print("Sorry, something went wrong. Enter integer value as age.")

   

Explanation:

The python code above lets the user input the age value for continuous comparison. If the age is an integer, it checks to know if the age is greater than 18 or not. If yes, it returns "Welcome!" else "Sorry, but you aren't old enough to use our app". But if the age is not an integer, it displays the message "Sorry, something went wrong. Can you please re-enter your age?" then prompts the user again for the age.

Note: the ': "String" ' and "->int" is for documentation purposes. They are used to describe the type of parameters (for later) and return value (the former).

Internet routing:_________. A. precomputes the most efficient route and uses it to ensure rapid packet delivery. B. broadcasts all packets to all hosts so the recipient will be sure to see its traffic. C. makes routing decisions one at a time as a packet crosses individual networks. D. uses port numbers to optimize the transmission of streaming media.

Answers

Answer:

A. precomputes the most efficient route and uses it to ensure rapid packet delivery.

Explanation:

In simple words, what Internet routing means is a process where a router decides which path data packets should follow that are more efficient in delivering the packets across computers.

For example, we can liken the process to the duties of a tour guide in a museum or large building in directing visiting guests who came to explore the museum.

Consider sending a packet from a source host to a destination host over a fixed route. List the delay components in the end-to-end delay. Which of these delays are constant and which are variable? Draw a picture to illustrate your network and where each type of delay occurs.

Answers

List the delay components in the end-to-end delay:
Processing delay
Transmission delay
Propagation delay
Queuing delay.
The processing delay, transmission delay, and propagation delay are constant. Reason is that, time taken to transmit data bits.
The queuing delay is variable.Reason is that, Only single packet transfer in queue process and waiting time depends on packet size.

The delay components in the end-to-end delay are processing delay, Transmission delay, Propagation delay, and Queuing delay.

What is an end-to-end Delay?

End-to-end delay, also known as one-way delay, is the length of time it takes for a packet to go from its source to its destination across a network. It is a word frequently used in the monitoring of IP networks, and it varies from round-trip time in that only the path from source to destination is measured.

Now according to the question, the propagation, transmission, and processing delays are all constant. The time required to send data bits is the cause.

Variable queuing delays exist.

The waiting time is dependent on packet size, and only one packet can be transferred at a time in the queue process.

Which role will grant a delegate read-only access to a particular workspace within a user’s Outlook mailbox?
Author
Editor
Contributor
Reviewer

Answers

The role that will grant a delegate read-only access to a particular workspace within a user's Outlook mailbox is the "Reviewer" role.

In Outlook, delegates are individuals who are granted permission to access and manage another user's mailbox on their behalf. When assigning delegate permissions, different roles can be assigned to control the level of access the delegate has.

The "Reviewer" role specifically provides read-only access to the specified workspace within the user's mailbox. Delegates with this role can view the content, including emails, calendar events, and other items, but they cannot make any changes or modifications.

On the other hand, the "Author" role grants read and write access, allowing delegates to create, modify, and delete items within the designated workspace. The "Editor" role also provides read and write access but includes additional privileges such as creating subfolders and managing permissions.

The "Contributor" role allows delegates to create items within the workspace, but they cannot view items created by others. It provides a limited level of access compared to the "Reviewer" role.

Therefore, if a delegate needs read-only access to a particular workspace within a user's Outlook mailbox, the "Reviewer" role should be assigned.
