Explanation:
Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 2 ms, Job B = 12 ms, Job C = 15 ms, Job D = 7 ms, and Job E = 3 ms.
Using FCFS, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for each of these five jobs?
This is an example with solution:
Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 12, Job B = 2, Job C = 15, Job D = 7, and Job E = 3 ms.
a. Using FCFS, and assuming the difference in arrival time is negligible, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?
Answer: The order of processing for the given jobs = A->B->C->D->E.
Total time needed to process all the jobs = 12+2+15+7+3 = 39 ms.
Turn around time for job A = 12 ms.
Turn around time for job B = 15 ms.
Turn around time for job C = 30 ms.
Turn around time for job D = 37 ms.
Turn around time for job E = 40 ms.
Answer : Therefore, the average turnaround time = (12+15+30+37+40)/5 = 26.8 ms.
Order of processing is A, B, C, D, E and Total time to process and Average turnaround time is 39 ms and 24 ms
Turnover time and order of processing:Order of processing = A, B, C, D, E
Total time to process all five jobs = Job A + Job B + Job C + Job D + Job E
Total time to process all five jobs = 2 + 12 + 15 + 7 + 3
Total time to process all five jobs = 39 ms
Average turnaround time = [(2-0) + (2+12-0) + (2+12+15-0) + (2+12+15+7-0) + (2+12+15+7+3-0)] / 5
Average turnaround time = (2+14+29+36+39) / 5
Average turnaround time = 24 ms

What is primary difference between the header section of a document and the body
Answer:
A HTML file has headers and a "body" (payload) — just like a HTTP request. The <body> encapsulates the contents of the document, while the <head> part contains meta elements, i.e., information about the contents. This is (typically) title, encoding, author, styling etc.

Problem: For multi access control, there are two approaches, those based on channel partitioning, and those based on random access. In packet switching, there are two rather similar approaches as well, namely, circuit switching and package switching. Discuss the similarities and differences in these two problem domains and the corresponding approaches g
The similarity between the two systems is the ability to connect many different communication devices and transfer data between a sender and a receiver. The main difference is the need for a connection for both to work.
We can arrive at this answer because:
Circuit and package quotation is very important for the connections of different communication devices.Furthermore, these two systems are used efficiently when a data transfer is required.However, even being used for the same purposes, they have many differences between them.The biggest difference is the need for a connection, as package switching is done without the need for a connection, while circuit switching needs a connection to act.In addition, circuit switching is more widely used because of its ability to transfer data from one point to another via message transfer, while package switching is used when circuit switching is not available as it does the sending data more slowly across one drive.

Turtle graphics windows do not automatically expand in size. What do you suppose happens when a Turtle object attempts to move beyond a window boundary
When a turtle object attempts to move beyond a window boundary, the turtle object stops because it cannot move outside the window boundary.
The turtle graphics window is simply a graphics window that is used as a playground when drawing turtles.
A turtle object is always in the turtle graphics window.
This in other words mean that, the turtle object cannot exceed the boundaries of the turtle graphics window
An attempt to move the turtle object outside its window will stop the turtle object;

What is the difference between (IF instructions & WHILE instructions )

Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.
Just a quick question, how do you set something == to char and int in an if statement (java)
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
Your program must define the method:
public String checkCharacter(String word, int index)
this is what i got to but im stuck on how to find out if its a char or int
public class TollCalculation {
public double calcToll(int hour, boolean isMorning, boolean isWeekend) {
Scanner scnr = new Scanner(System.in);
int timeHour; // Time of travel hour (24 hour format)
int timeMinute; // Time of travel minute
int inputColon; // Used to read time format
String userInput; // User specified time
double tollAmount;
}
public static void main(String[] args) {
TollCalculation tollObj = new TollCalculation();
// Test the three samples from the specification.
System.out.println(tollObj.calcToll(7, true, false));
System.out.println(tollObj.calcToll(1, false, false));
System.out.println(tollObj.calcToll(3, true, true));
}
}
This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.
