Answer:
Scheduling.
Explanation:
A scheduling computer system refers to an ability of the computer that typically allows one process to use the central processing unit (CPU) while another process is waiting for input-output (I/O), thus making a complete usage of any lost central processing unit (CPU) cycles in order to prevent redundancy.
Hence, the task of handling how active processes are making efficient use of the central processing unit (CPU) processing cycles is called scheduling.
In terms of the scheduling metrics of a central processing unit (CPU), the time at which a job completes or is executed minus the time at which the job arrived in the system is known as turnaround time.
Generally, it is one of the scheduling metrics to select for optimum performance of the central processing unit (CPU).

if there was no technological advancement what would be our society like
Answer:
WHAT SOCIETY?!
Every night we'd still be squatting in caves, hunched around campfires, waiting for the leopards to pick us off....
It's hard to have a society when your means of communication are nearly zero and therefore can't sustain the dialogue necessary to develop the shared values needed to form a society.
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
}
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).
Using a for loop, write a function lastfirst() that takes a list of strings as a parameter. Each string in the list has the format 'Last, First' where Last is a last name and First is a first name. You should assume that there are no spaces between the last name and the comma and that there are an arbitrary number of spaces between the comma and the first name. The function lastfirst() returns a list containing two sub lists. The first sub list is a list of all the first names and the second sub list is a list of all the last names. The following shows how the function would be called on two example parameters:>>> lastfirst(['Lulis, Evelyn', 'Jones, Tom', 'Presley, Elvis', 'Sumner, Gordon'])[['Evelyn', 'Tom', 'Elvis', 'Gordon'], ['Lulis', 'Jones', 'Presley', 'Sumner']]>>> lastfirst(['Ford, Harrison', 'Hepburn, Katharine', 'Tracy, Spencer'])[['Harrison', 'Katharine', 'Spencer'], ['Ford', 'Hepburn', 'Tracy']]
def lastfirst(lst):
newlst = []
newlst1=[]
for x in lst:
w = x.split(",")
newlst.append(w[1].strip())
newlst1.append(w[0].strip())
newlst2 = [newlst], [newlst1]
return newlst2
lst1 = (['Lulis, Evelyn', 'Jones, Tom', 'Presley, Elvis', 'Sumner, Gordon'])
print(lastfirst(lst1))

In the rapid application development (RAD) model, the _____ phase focuses on program and application development tasks similar to the SDLC.A) requirements planningB) user designC) constructionD) cutover
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.
Write a method named printGPA that takes in as a parameter a Scanner to read in user input, and calculates a student's grade point average.

Here are two example dialogues: Enter a student name: Maria Enter the number of courses: 5 Course 1 Grade: 72 Course 2 Grade: 91 Course 3 Grade: 84 Course 4 Grade: 89 Course 5 Grade: 78 Maria's grade is 82.8 Enter a student name: Jordan Enter the number of courses: 4 Course 1 Grade: 86 Course 2 Grade: 71 Course 3 Grade: 62 Course 4 Grade: 90 Jordan's grade is 77.25
import java.util.Scanner;
public class JavaApplication40 {
public static void printGPA(Scanner scan){
System.out.println("Enter a student name:");

Super Scores
I am sure all of you know about SAT Superscore. Superscoring is the process by which colleges consider the highest section scores across all the dates a student took the SAT. Rather than confining the scores to one particular date, this approach will take the student's highest section scores, forming the highest possible composite score. Let us solve a generic problem here. Let us start with a sample input and output 2 3
700 800 775 775 800 700 800 800 1600
First line of input specifies 2 sections and 3 takes for this student. So, we need to find the best score for each section across all the test takes & output the best section scores and the corresponding total - next 3 lines show the scores for each section for each take - For this sample input/output, student got 800 in both sections, so the final total is 1600 Your program should be generic to handle any # of sections and any # of takes 2591421130838 5 int main() 6 int nursections, nuntakes, naxScores; cin >> nun sections >> nuntakes; 9 maxScores - new int [numSections); //dynamic memory allocation of arnay! 10 11 // initialize the array 12 for(int 1-e; Icnum Sections; i++) 13 maxScores[1] - ; 14 15 //CODE HERE 16 17 1/output the max score for each section and compute & output total too. 18 int total -e; 19 for(int 1-e; Icnum Sections; 1.) { 20 cout << maxScores[1] << **; 21 total + maxScores[i]; 22 ) 23 cout << total; 24 ) I
Answer:
Replace:
//CODE HERE
//output the max score for each section and compute & output total too.
with the following lines of codes:
int num;
for(int i=0; i<numtakes; i++) {
for(int j=0; j<numsections; j++) {
cin>>num;
if(num>maxScores[j]){
maxScores[j] = num; }
} }
Explanation:
Your program is poorly formatted. (See attachment for correct presentation of question)
What's required of the us is to complete the source program.
The codes has been completed in the Answer section above, however, the line by line explanation is as follows:
This line declares num that gets user for input for each entry
int num;
This line iterates through the number of takes
for(int i=0; i<numtakes; i++) {
This line iterates through the number of sections
for(int j=0; j<numsections; j++) {
This gets user input for each entry
cin>>num;
The following if condition determines the greatest entry in each section
if(num>maxScores[j]){
maxScores[j] = num; }
} }
For further explanation, I've added the complete source file as an attachment where I used comments to explain each line.

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.

Crowdsourcing is not only used for relatively simple tasks such as designing a Web site or designing a case for a smartphone. Today, it is increasingly being used in more complex designs as well. Precyse Technologies provides supply-chain products and solutions that assist organizations in tracking their inventories using RFID technology. It was having difficulty improving the performance and battery life of a particular RFID device; there were not adequate internal resources to tackle the problem. So, Precyse asked InnoCentive, a crowdsourcing provider, for assistance, believing that crowdsourcing would provide quick access to a worldwide talent pool and a higher return on investment (ROI). Ultimately, the company received more than 300 ideas from global experts for solving its problem. It narrowed the pool down to three finalists, from which a winner was chosen. The whole process took approximately four months, and Precyse estimated that it saved the company $250,000. 1. What are some typical applications of crowdsourcing? 2. What are some advantages of crowdsourcing? 3. How could crowdsourcing reduce the systems design cost and are there certain problems you would not want to use crowdsourcing to solve?
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.
This helps to gather or seeks money to aid individuals, charities, or for one to start a business. The advantages of crowdsourcing are cost savings, speed, etc.Crowdsourcing is known to help man to remove the various costs due to functioning as a pay-per-task model.
A well managed crowdsourcing can be used to pay workforce.

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

An important communication principle states ""prepare before you communicate."" How should this preparation manifest itself in the early work that you do? What work products might result as a consequence of early preparation?
Answer:
Planning is very important before communicating a product to others.
Explanation:
We should always prepare well about what we are going to communicate to others. We should know the topic properly or know about the product before we speak about it in front of others. We should understand the concept of the product before we communicate it to others.
Planning is also an important before going to speak or communicate.
Before communicating a product to others, we should prepare :
1. We should very well understand the concept of the product also its scope. The scope will provide product team with the destinations.
2. We should keep in mind to involve the valuable customers in our plannings.They defines the priorities of the product.
3. We should recognize that the planning is highly iterative.
4. We should do a market research or study or the business domain that the product will address.
5. We should understand the different stakeholders and their requirements and be open to negotiations.
It is vital to prepare in every communication as your success depends on it. One can prepare by researching on the area we want to talk about and practicing one's speech.
Why do we need to prepare in communication?The success one has in communicating is said to be a skill that is often used in a lot of field of work.

Assume that you want two C# or C++ programs to share some data. You can write the first program so that it writes it's output to a file, and then write the second program so that it reads the data from this file. However this process can be difficult and time consuming, especially if you don't know how to program in C# or C++. What feature of the UNIX/Linux shell can you use to simplify the process of sharing data between programs?
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.

Given six memory partitions of 300 KB, 600 KB, 350 KB, 200 KB, 750 KB, and 125 KB (in order). The memory allocation algorithm that is used to place processes of size 115 KB, 500 KB, 358 KB, 200 KB, and 375 KB in the following order is the _______________.
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.

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