Which of the following is considered an input device?

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.

Answer:

True

Explanation:

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.

Answer:

C) construction

Explanation:

Rapid application development abbreviated RAD is an agile software development strategy that reduces time spent on planning so that prototype development takes priority and project turnaround time is greatly reduced consequently. There are four phases in rapid application development :

requirements planning, user design, construction, cutover

The construction phase is the third stage in rapid application development. This stage builds on the progress of the previous stages- the requirements planning stage and user design stage- to go ahead to finalize the application development which has been agreed on through iterations and communication between developer and client in the user design stage. In other words, this stage basically takes the ideas, prototypes and beta products from the previous stages and makes it into a real final product. The rationale or perks behind this is that other problems such as what product would do or look like or any changes or modifications have been worked out in previous stages thereby speeding up development in this stage.

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.

1) SOME APPLICATIONS OF CROWD SOURCING ARE;

- MARKETING STRATEGY; There is finalizing of marketing strategies by firms and this is based on the crowd sourcing ideas.

- THOUGHT LEADERSHIP; There has been catering to crowdsourcing for high level thought leadership by many firms and this is done in various fields such as Human resources.

- DESIGNING; Designing is very common for crowdsourcing and this is seen where a bunch of talent pool is being used for the purpose of designing websites,applications and as well as other prototypes.

SOME OF THE ADVANTAGES OF CROWDSOURCING ARE;

- An individual can actually save lots of costs,this is because they don't need to hire a permanent resource and this resource can be quite expensive.

- Another advantage of crowdsourcing is that one can actually get services and idea from pool of professionals that are far talented across the world.

- It also play a role in obtaining of ideas from a group of people and this can go a way in shortening the resolution process, therefore saving time.

CROWDSOURCING HELPS IN GETTING IDEAS AND SERVICES FROM A WIDER POOL OF PROFESSIONALS THAT ARE TALENTED,So;

Lots of time are being saved when there is actually a large talent pool.

This then translates into shorter span in the system design process and it also results in the saving of costs.

However,a firm don't necessarily need to hire permanent resources for critical inputs I'm the design process and this also results in saving of costs s well.

People are known to be using Crowdsourcing. The applications of crowdsourcing is often done so as to gather information or work product.

Crowdsourcing is known to help man to remove the various costs due to  functioning as a pay-per-task model.

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!";

var res = str.replace("Trump", "Biden", str);

Hence, in this case, the correct answer is strVar.replace(pos, n, str);

Answer:

The memory allocation algorithm that is used to place the processes given is the First Fit Algorithm

Explanation:

The First Fit Management Algorithm works by ensuring that the pointer keeps track of all the free spaces in the memory and accepts and executes all instructions to allocate a memory block to the coming process as long as it is big enough to hold the size of the process.

For example, the First Fit algorithm will allocate the processes in the first block that fits (that is, if it can fit the memory bock in the queue, then the process will be store)

It will work as follows (recall that the memory partitions are in order and must remain so):

A) 115 KB is stored in 300KB block, leaving the following free spaces (185KB, 600KB, 350KB, 200KB, 750KB, 125KB), next

B) 500 KB is store in a 600KB block leaving the following free spaces (185 KB, 100  KB, 350 KB, 200 KB, 750 KB, 125 KB), next  

C) 358 KB is stored in 750KB block, leaving the following free spaces (185KB, 100KB, 350KB, 200KB, 392KB, 125KB)  next

D) 200 KB is stored in 350KB block, leaving the following free spaces (185 KB, 100 KB, 150KB, 200KB, 392KB, 125KB)  next

E) 375KB is stored in 392KB block leaving (185KB, 100KB, 150KB,  200KB, 17KB, 125KB)

One of the demerits of this Algorithm is that, as shown above, memory is not maximized. It however is one of the easiest algorithms amongst all the other memory allocation processes.

Answer:

C

Explanation:

ed 2021

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).

Certain ways exist to simplify the process of data sharing between programs.some of these ways are;

A) When there are two programs that are not running at the same time,then the pipes or the sockets won't be able to work as their buffers would not be able to hold large files because they are small.

Looking at this scenerio,shared memory can be used.

The Sysv IPC shared memory API, POSIX shared the memory API or rather files on a tmpfs system of files can actually be used for shared memory operations.

B) Another possible solution can be named file. Instead of using an unnamed and shell pipeline,a name pipeline them uses the file system.

However,it can be treated with the use of mkfifo() or mknod() commands and then two separate programs or also processes can as well access the pipe by making use of the name of the pipe.

But one process(program) can actually open the pipe but as a reader for reading purposes and the other for writing purposes as a writer.
