The available options are:
Emails
Financial spreadsheets
User downloads
Databases
Answer:
User downloads
Explanation:
The correct answer is User downloads, this is because, the downloaded files are in cloud or another website memory or database, which serves as an alternative backup already. Thus, those downloaded files can still be recovered at later time when one needs to get the files back.
However, Emails, Financial spreadsheets and Databases, do not have any other place to retrieve them, because they are originally created and are yet to be uploaded to cloud or another website memory space to serves as alternative back up.
Assuming storage limitations, which of these is LEAST important to back up is; User downloads
The missing options are;
Emails
Financial spreadsheets
User downloads
Databases
The correct option is User downloads. The reason for that is because files under user downloads can still be located on the website from which it was downloaded or if it was stored in cloud storage or some other online platform. This means that it is already a backup even if you delete it as you can always re-download. However, the other options were created by you and not downloaded and as such if deleted could never be recovered again.Thus, user downloads is the LEAST important to back up.

Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output with input 2:1: Lather and rinse.2: Lather and rinse.Done. Hint: Declare and use a loop variable.#include /* Your solution goes here */int main(void) {int userCycles;scanf("%d", &userCycles);PrintShampooInstructions(userCycles);return 0;}
Answer:
Function 1:#include <stdio.h> //for using input output functions
// start of the function PrintPopcornTime body having integer variable //bagOunces as parameter
void PrintPopcornTime(int bagOunces){
if (bagOunces < 3){ //if value of bagOunces is less than 3

/*the following else part will execute when the above If and else if conditions evaluate to false and the value of bagOunces is neither less than 3 nor greater than 10 */
else {
/* The following three commented statements can be used to store the value of bagOunces * 6 into result variable and then print statement to print the value of result. The other option is to use one print statement printf("%d",bagOunces * 6) instead */
//int result;
//result = bagOunces * 6;
//printf("%d",result);
printf("%d",bagOunces * 6); /multiplies value of bagOunces to 6
printf(" seconds");
// seconds is followed with the value of bagOunces * 6
printf("\n"); }} //prints a new line
int main(){ //start of main() function body
int userOunces; //declares integer variable userOunces
scanf("%d", &userOunces); //reads input value of userOunces
PrintPopcornTime(userOunces);
//calls PrintPopcornTime function passing the value in userOunces
return 0; }
Explanation:
Function 2:#include <stdio.h> //header file to use input output functions
// start of the function PrintShampooInstructions body having integer variable numCycles as parameter
void PrintShampooInstructions(int numCycles){
if(numCycles < 1){
//if conditions checks value of numCycles is less than 1 or not
printf("Too few."); //prints Too few in output if the above condition is true
printf("\n"); } //prints a new line
//else if part is executed when the if condition is false and else if checks //value of numCycles is greater than 4 or not
else if(numCycles > 4){
//prints Too many in output if the above condition is true
printf("Too many.");
printf("\n"); } //prints a new line
//else part is executed when the if and else if conditions are false
else{
//prints "N: Lather and rinse." numCycles times, where N is the cycle //number, followed by Done
for(int N = 1; N <= numCycles; N++){
printf("%d",N);
printf(": Lather and rinse. \n");}
printf("Done.");
printf("\n");} }
int main() //start of the main() function body
{ int userCycles; //declares integer variable userCycles
scanf("%d", &userCycles); //reads the input value into userCycles
PrintShampooInstructions(userCycles);
//calls PrintShampooInstructions function passing the value in userCycles
return 0;}
I will explain the for loop used in PrintShampooInstructions() function. The loop has a variableN which is initialized to 1. The loop checks if the value of N is less than or equal to the value of numCycles. Lets say the value of numCycles = 2. So the condition evaluates to true as N<numCycles which means 1<2. So the program control enters the body of loop. The loop body has following statements. printf("%d",N); prints the value of N followed by
printf(": Lather and rinse. \n"); which is followed by printf("Done.");
So at first iteration:
printf("%d",N); prints 1 as the value of N is 1
printf(": Lather and rinse. \n"); prints : Lather and rinse and prints a new line \n.
As a whole this line is printed on the screen:
1: Lather and rinse.
Then the value of N is incremented by 1. So N becomes 2 i.e. N = 2.
Now at second iteration:
The loop checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to true as N<numCycles which means 2=2. So the program control enters the body of loop.
printf("Done."); prints Done after the above two lines.
printf("%d",N); prints 2 as the value of N is 2
printf(": Lather and rinse. \n"); prints : Lather and rinse and prints a new line \n.
As a whole this line is printed on the screen:
2: Lather and rinse.
Then the value of N is incremented by 1. So N becomes 2 i.e. N = 3.
The loop again checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to false as N<numCycles which means 3>2. So the loop breaks.
Now the next statement is:
printf("Done."); which prints Done on the screen.
So as a whole the following output is displayed on the screen:
1: Lather and rinse.
2: Lather and rinse.
Done.
The programs along with their outputs are attached.

Because Java byte code is the same on all computers, compiled Java programs Group of answer choices Cannot run on Linux systems Must be re-compiled for each different machine it is run on Are highly portable Are non-existent
Answer:
Are highly portable.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.
Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.
Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.
Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.
Hence, the Java byte code is a write once, run anywhere software program.
The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).
Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.

The instruction format of a computer is given by one indirect bit, opcode bits, register address bits, immediate operand bits and memory address bits. It occupies one memory word of 64 bits.
a- How many memory addresses can be generated if the memory size is 1 Giga Bytes (Giga-2)? Number of addresbits Number of addresses
b- Complete the missing fields in the following instruction format, given that the number of opcodes is 128, the immediate operand field occupies 24 bits and the instruction occupies one memory word Opcode Register address Immediate operand Memory address
c- If the immediate value is increased by combining it with the address field in the above instruction. Find the largest positive and smallest negative immediate values that can be stored on the address field, before and after combining it with the address field. Range before combining (+ Range after combining-+
Answer:
Following are the answer to this question:
Explanation:
A)
The memory size is 1 Giga Bytes which is equal to [tex]2^{30}[/tex]
[tex]\texttt{Number of address bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ Number of addresses}\\\\ \ \ \ \ 30 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2^{30}= 1073741824[/tex]
B) [tex]\texttt{I \ \ \ Opcode \ \ \ Register address \ \ \ Immediate operand \ \ \ Memory address}\\\\\\\textt{1 \ bit \ \ \ \ \ \ 128 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 24 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 30 \ bits}\\\\\\[/tex] [tex]= 2^7 \\\\ = 7 \ bits[/tex]
calculating the register Bits:
[tex]= 64-(1+7+24+30)\\\\=64 -62\ \ bits\\\\= 2\ \ bits\\[/tex]
C)
Immediate value size while merging the additional benefit with the address field:
[tex]= 2^{24} + 2^{30}\\\\= 2^{54}\\\\[/tex][tex]\texttt{Range before combining(-,+) 24 bits \ \ \ \ \ \ Range after combining( -,+)54bits}\\\\[/tex] [tex]\textt{-2^{12} from + (2^{12}-1) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -2^{27} from + (2^{27}- 1)}[/tex]
[tex]= \frac{24}{2} = 12\\\\= \frac{54}{2} = 27[/tex]
The range is accomplished by dividing the bits by 2 into the two sides of the o and the number is one short to 0.
Write a method named isPalindrome that accepts a string parameter and returns true if that string is a palindrome, or false if it is not a palindrome. For this problem, a palindrome is defined as a string that contains exactly the same sequence of characters forwards as backwards, case-insensitively. For example, "madam" or "racecar" are palindromes, so the call of isPalindrome("racecar") would return true. Spaces, punctuation, and any other characters should be treated the same as letters; so a multi-word string such as "dog god" could be a palindrome, as could a gibberish string such as "123 $$ 321". The empty string and all one-character strings are palindromes by our definition. Your code should ignore case, so a string like "Madam" or "RACEcar" would also count as palindromes.
Answer:
The programming language is not stated;
However, I'll answer this question using Java Programming Language;
The method is as follows;
public static void isPalindrome(String userinput)
{
String reverse = "";
int lent = userinput.length();
int j = lent - 1;
while(j >= 0)
{
reverse = reverse + userinput.charAt(j);
j--;
}
if(reverse.equalsIgnoreCase(userinput))
{
System.out.println("True");
}
else
{
System.out.println("False");
}
}
Explanation:
This line defines the method isPalindrome with a string parameter userinput
public static void isPalindrome(String userinput) {
This line initializes a string variable
String reverse = "";
This line gets the length of the userinput
int len = userinput.length();
The following while-loop gets the reverse of userinput and saved the reversed string in reverse
int j = lent - 1;
while(j >= 0)
{
reverse = reverse + userinput.charAt(j);
j--;
}
The following if statement checks if userinput and reverse are equal (cases are ignored)
if(reverse.equalsIgnoreCase(userinput))
{
System.out.println("True"); This line is executed if the if condition is true
}
else
{
System.out.println("False"); This line is executed if otherwise
}
} The method ends here
The score of a student in two subjects are inserted in the B2 and C2 cells and the passing score for each subject is 60. Which of these functions will you insert in the D2 cell so that it returns TRUE if at least one score is greater than or equal to 60, or else it returns FALSE
Answer:
=OR(B2>=60, C2>=60)
Explanation:
If you want to check if at least one of the scores is equal to or greater than 60, you should use the OR function. The OR function tests multiple conditions and returns TRUE if at least one is met. Therefore, the function in cell D2 would be:
= OR(B2>=60, C2>=60)
In other to obtain the boolean value True if one of two or more conditions are met, the OR operator is used. Hence, the appropriate function is =OR(B2>=60, C2>=60)
The OR opertor gives a True value if one of the two conditions is met., if the student scores 60 or above in one of the two subjects, the output will be True. Similarly, if the student score above 60 in both, the output will be true.Hence, the appropriate function is =OR(B2>=60, C2>=60).

Write down an encryption solution that best prevents a competitor from receiving confidential information and justify the recommendation.
Answer:
The Encryption solution that best prevents a competitor from receiving confidential information is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
Explanation:
Solution:
From my own perspective the encryption solution that i will use that prevents s a competitor from receiving confidential information and justify the recommendation is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
This is because in this case we have to share data confidentially (information need to be hidden from Unauthorized security access. also these provides the Transport Layer security that we needed in above example above.
The purpose of these protocol is to provide server and client authentication, Data confidentiality,and Data integrity (protected from unauthorized change). Application Layer client/server program such as HTTP that uses the service of TCP can encapsulate their data in SSL Packets.
SSL (Secure Socket Layer): is defined as the normal technology for protecting an internet connection secure and defend any sensitive data that is being sent between two systems, and not allowing criminals from reading and changing any information sent, including potential personal details.
TLS (Transport Layer security): It is a procedure that allows data integrity and privacy over Internet communications.
Letm1, m2,···mnbe distinct numbers on the number line, in the increasing order. Your goalis to color all of them blue. You have magical blue pens with the following property: Whenyou place the pen at co-ordinate x, all the points in the range [x - 5, x + 5] turn blue. Apen can be used only once. Give an algorithm to color all the points using as few pens aspossible. Prove the correctness of the algorithm and derive the runtime.
Answer:
Following are the algorithm to this question:
y = 0 // initialize variable y that assigns the value 0
p = 1 // initialize value 1 in the variable p which also known as starting position
init num = 1//define variable num that assign value 1
for j = 1 to n: //defining loop
y = m[j] - m[p]
if (y > 10) //defining if block
num++; //increment num variable
p=i; //holding loop value in p variable
y= 0//assign value 0 in y variable
Explanation:
Following are the runtime analysis of the above-given algorithm:
The above-provided algorithm is greedy, but if it doesn't exceed the scope, it operates by greedily choosing its next object. Therefore the algorithm selects the fewest number of pens.
Running time:
This algorithm merely iterates once over all the points. The run-time is therefore O(n).

a. A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2, 048 sectors and there are 131, 072 (2^17) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk?
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)
Answer:
Explanation:
Given that:
number of surfaces on a hard disk = 4
number of sectors = 2048 sectors
number of tracks per surface = 131, 072 (2^17)
a block holds 512 bytes.
Since, 'The disk is not "zoned.".....
then, Number of bytes / sector = 512
a) What is the total capacity of this disk?
The total capacity of the disk is:[tex]= 4 \ surfaces \times 131072 \dfrac{tracks}{surfaces} \times 2048 \dfrac{sector}{tracks} \times 512 \dfrac{bytes}{sector}[/tex]
[tex]= 5.49755814\times 10^{11} \ bytes[/tex]
= 549755814 KB ( kilobytes)
= 549755.814 MB (megabytes)
=549.755814 GB (gigabytes)
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (i.e what is the capacity of one cylinder?)
The capacity of one cylinder can be estimated by determining the capacity of one surface and the capacity of one track.
The capacity of one surface = [tex]131072\dfrac{tracks}{surface} \times 2048 \dfrac{sector}{tracks} \times 512\dfrac{bytes}{sector}[/tex]
The capacity of one surface = [tex]1.37438953 \times 10^{11[/tex] byte = 137.44 GB
Capacity of one track = 2048 sectors/track × 512 bytes/sector
Capacity of one track = 1048576 Bytes/track
Capacity of one track =1048 KB/track
Capacity of one track ≅ 1 MB/track
Since the hard disk contains four surfaces
∴
capacity of one cylinder = 1 MB/track × 4 track/cylinder
capacity of one cylinder = 4 MB
Modify short_names by deleting the first element and changing the last element to Joe. Sample output with input: 'Gertrude Sam Ann Joseph'
Answer:
I am writing a Python program:
For taking input from user:
user_input = input() # takes input from user
short_names = user_input.split() #splits user_input into list of strings
short_names.pop(0) # removes the first element of the list i.e. Gertrude
short_names[-1] = "Joe" #sets the last element to Joe
print(short_names) #prints modified list of Sam Ann Joe
If you do not want to take input from user:
short_names=['Gertrude', 'Sam', 'Ann', 'Joseph'] #list of 4 elements
short_names=short_names[1:] # removes the first element Gertrude
short_names.pop() # removes last element i.e. Joseph from list
short_names.append('Joe') #adds Joe to the end of the list
print(short_names) #prints modified list Sam Ann Joe
If you do not want to use pop() and append() methods:
short_names = ['Gertrude', 'Sam', 'Ann', 'Joseph'] #creates list of 4 values
short_names = short_names[1:] # removes first value i.e. Gertrude from list
short_names[-1] = "Joe" #set the last element to Joe
print(short_names) #prints modified list Sam Ann Joe
Explanation:
The first program takes the names from the user, splits them into list of strings, then pop(0) has given index value 0 which means 1st value in the list. So it removes and returns first value from the list. Next statement sets the last value of list to Joe.
The second program has a hard coded list ['Gertrude', 'Sam', 'Ann', 'Joseph']
short_names = short_names[1:] removes the first value of the short_names list i.e. Gertrude. Next pop() removes and returns last value in the list i.e. Joseph from list. Last statement append('Joe') adds Joe to the end of the list.
The third program has a list of 4 elements. short_names = short_names[1:] removes first value i.e. Gertrude from list and short_names[-1] = "Joe" sets the last element to Joe.
The function was implemented using the JavaScript language, the shift, pop and push function was used to get the desired output
Array and String OperationsThe function bellow is written in JavaScript
function shortName (short_names){
short_names.shift() // The first element "Gertrude" was removed
short_names.pop() //The last element "Joseph" was removes
short_names.push("joe") //"Joe" is added to the new list
return short_names //The new list is returned as output

(Displaying a Sentence with Its Words Reversed) Write an application that inputs a line of text, tokenizes the line with String method split and outputs the tokens in reverse order. Use space characters as delimiters.
Answer:
I am writing a JAVA and Python program. Let me know if you want the program in some other programming language.
import java.util.Scanner; // class for taking input from user
public class Reverse{ //class to reverse a sentence
public static void main(String[] args) { //start of main() function body
Scanner input = new Scanner(System.in); //create a Scanner class object
System.out.print("Enter a sentence: "); //prompts user to enter a sentence
String sentence = input.nextLine(); // scans and reads input sentence
String[] tokens = sentence.split(" "); // split the sentence into tokens using split() method and a space as delimiter
for (int i = tokens.length - 1; i >= 0; i--) { //loop that iterates through the tokens of the sentence in reverse order
System.out.println(tokens[i]); } } } // print the sentence tokens in reverse order
Explanation:
In JAVA program the user is asked to input a sentence. The sentence is then broken into tokens using split() method. split method returns an array of strings after splitting or breaking the sentence based on the delimiter. Here the delimiter used is space characters. So split() method splits the sentence into tokens based on the space as delimiter to separate the words in the sentence. Next the for loop is used to iterate through the tokens as following:
Suppose the input sentence is "How are you"
After split() method it becomes:
How
are
you
Next the loop has a variable i which initialized to the tokens.length-1. This loop will continue to execute till the value of i remains greater than or equals to 0.
for (int i = tokens.length - 1; i >= 0; i--)
The length of first token i.e you is 3 so the loop executes and prints the word you.
Then at next iteration the value of i is decremented by 1 and now it points at the token are and prints the word are
Next iteration the value of i is again decremented by i and it prints the word How.
This can be achieved in Python as:
def reverse(sentence):
rev_tokens = ' '.join(reversed(sentence.split(' ')))
return rev_tokens
line = input("enter a sentence: ")
print((reverse(line)))
The method reverse takes a sentence as parameter. Then rev_tokens = ' '.join(reversed(sentence.split(' '))) statement first splits the sentence into array of words/tokens using space as a delimiter. Next reversed() method returns the reversed sentence. Next the join() method join the reversed words of the sentence using a space separator ' '.join(). If you want to represent the reversed tokens each in a separate line then change the above statement as follows:
rev_tokens = '\n'.join(reversed(sentence.split(' ')))
Here the join method joins the reversed words separating them with a new line.
Simply input a line of text and call this reverse() method by passing the input line to it.
Write a program that asks the user to input a positive integer and then calculates and displays the factorial of the number. The program should call a function named getN
Answer:
The program is written in python and it doesn't make use of any comment;
(See explanation section for line by line explanation)
def getN(num):
fact = 1
for i in range(1, 1 + num):
fact = fact * i
print("Factorial: ",fact)
num = int(input("Number: "))
if num < 0:
print("Invalid")
else:
getN(num)
Explanation:
The function getNum is defined here
def getN(num):
Initialize the result of the factorial to 1
fact = 1
Get an iteration from 1 to the user input number
for i in range(1, 1 + num):
Multiply each number that makes the iteration
fact = fact * i
Print result
print("Factorial: ",fact)
Ths line prompts user to input number
num = int(input("Number: "))
This line checks if user input is less than 0; If yes, the program prints "Invalid"
if num < 0:
print("Invalid")
If otherwise, the program calls the getN function
else:
getN(num)
A network technician is designing a network for a small company. The network technician needs to implement an email server and web server that will be accessed by both internal employees and external customers. Which of the following would BEST secure the internal network and allow access to the needed servers?

A site-to-site configuration is something that a single Open VPN network links several more separate networks linked. Technologies through one network will access machines in all the other computer systems in that connection model, including conversely. Implementing this would be extremely straightforward, for as much further even though Access Server was indeed implicated.The much more challenging aspect happens when interacting regarding firewalls including privacy filtering methods, as well as modifying the forwarding table in internet gateways, as several of them from different manufacturers but instead prototypes which they may not be able to log many of these.This rather gateway device uses an Open VPN with a Linux VPN client, to create a connection between various channels. If someone's server hardware is also measured accurately then perhaps a site-to-site configuration could be accomplished which works straightforwardly throughout all systems in both cable systems.Other choices are not related to the given instance. So that Option A would be the right one.
A bank in your town updates its customers’ accounts at the end of each month. The bank offers two types of accounts: savings and checking. Every customer must maintain a minimum balance. If a customer’s balance falls below the minimum balance, there is a service charge of $10.00 for savings accounts and $25.00 for checking accounts. If the balance at the end of the month is at least the minimum balance, the account receives interest as follows:
a. Savings accounts receive 4% interest.
b. Checking accounts with balances of up to $5000 more than the minimum balance receive 3% interest; otherwise, the interest is 5%.
This Java program using Eclipse Indigo reads a customer’s account number ( int type ), account type ( char type; s or S for savings, c or C for checking), minimum balance that the account should maintain, and current balance. The program should then output the account number, account type, current balance, and new balance or an appropriate error message. Test program by running it five times, using the following data:
46728 S 1000 2700
87324 C 1500 7689
79873 S 1000 800
89832 C 2000 3000

Answer:
This is your corrected code and the output of each test example. I have also added comments with the provided code to make the code understandable. I have also changed itype variable to from int to String in order to print the account type (Savings or Checking) in output.
import java.util.*;

{int num,error=1; //declare variables
String itype=" "; //stores Checking or Savings account type
char type =0; //type variable which is one of savings S or checking C
double min,cur =0,balance =0,rate=0;
//declare variables for minimum balance, current balance, interest rate
Scanner in=new Scanner(System.in);
System.out.println("Enter account number: "); //prompts user to enter acc no
num=in.nextInt(); //reads input account number
while(error==1) {
//asks user to enter account type C or S
System.out.println("Enter account type(s-savings or c-checking):");
type=in.next().charAt(0); //reads the input character of account type
if(type=='c'||type=='C') //if user inputs c or C
{itype= "Checking"; //set itype to Checking when user input c or C
error=0; //set value of error to 0 means user entered valid type input
rate=3/100.; } // Savings accounts receives 3% interest
else if(type=='s'||type=='S') //if user enters S or s that shows Savings account
{itype= "Savings"; //set itype to Savings when user input s or S
error=0; //set error to 0 means there is no error
rate=4/100.; } //Savings accounts receives 4% interest
if(error==1) //in case of error in giving input
System.out.println("Invalid type-re enter"); } //asks user to input again
System.out.println("Enter minimum balance: "); //asks user to enter min bal
min=in.nextDouble(); //reads value of input minimum balance
System.out.println("Enter current balance: ");

/* as the program should output account number, account type, current balance, and new balance so i have commented out the extra print statements below */
//System.out.printf("After interest and fees your balance is = $%.2f\n",cur);
System.out.println("Account Number: " + num);

In the Programming Process which of the following is not involved in defining what the program is to do:_____________ Group of answer choices
a. Compile code
b. Purpose
c. Output
d. Input
e. Process
Answer:
a. Compile code
Explanation:
In programming process, the following are important in defining what a program is to do;
i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program. The purpose of a program should be defined in the program.
ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.
iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.
iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.
Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.
Select the option that is not true. 1. Timestamp and Validation schedulers are both optimistic schedulers. 2. Timestamp and Validation schedulers can be used to remove physically unrealizable behaviour. 3. Timestamp and Validation schedulers guarantee serializability. 4. Timestamp and Validation schedulers perform most effectively on transactions that perform writes.
Answer:
3. Timestamp and Validation schedulers guarantee serializability.
Explanation:
Timestamp is a sequence of information encoded when a certain event occurs at a given time that information is decoded and message is identified. Time schedulers is optimistic scheduler and it removes physically unrealizable behavior. Timestamp cannot guarantee serializability. It can detect unrealizable behavior.

It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program.
A. True
B. False
Answer:
True
Explanation:
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.
Hope this helps.
The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:
NoWhat is a Test Case?This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.
With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10)
#include
/* Your solution goes here
*/ int main(void) {
const int SORT_ARR_SIZE = 4;
int sortArray[SORT_ARR_SIZE];
int i;
int userNum;
for (i = 0; i < SORT_ARR_SIZE; ++i) {
scanf("%d", &sortArray[i]);
}
SwapArrayEnds(sortArray, SORT_ARR_SIZE);
for (i = 0; i < SORT_ARR_SIZE; ++i) {
printf("%d ", sortArray[i]);
}
Answer:
Here is the SwapArrayEnds()
//function with two parameters; the array and array size
void SwapArrayEnds(int sortArray[],int SORT_ARR_SIZE){
int temp; //temporary variable to hold the first element of sortArray
if(SORT_ARR_SIZE > 1){ //if sortArray size is greater than 1
temp = sortArray[0]; // set value of temp to the first element of sortArrray
sortArray[0] = sortArray[SORT_ARR_SIZE-1]; // set the value of first element of sortArray to the last element of sortArray
sortArray[SORT_ARR_SIZE-1] = temp; } } // set last element value to temp
Explanation:
Lets understand the working of the above function with the help of an example. Suppose the sortArray has the following elements: {10,20,30,40}. So the size of this array is 4.
if(SORT_ARR_SIZE > 1) has an if statement which checks if the array size is greater than 1. This condition evaluates to true as 4 > 1. So the body of if condition executes.
Next the statement temp = sortArray[0]; sets the value of temp variable to the value of first element of sortArray. As sortArray[0] means the element at 0-th index position of the sortArray. So using the above example the first element of the array is 10. So temp = 10.
Next the statement sortArray[0] = sortArray[SORT_ARR_SIZE-1]; sets the last element of the sortArray to the position of first element of the sortArray.
SORT_ARR_SIZE-1 is the position of last element of the array. As the size of sortArray is 4, so 4-1 = 3 which points to the last element. Now this element is moved to the first position of the array. This means that the value of first element of array becomes 40 as the element at 3-th index of the sortArray is 40.
Next the statement sortArray[SORT_ARR_SIZE-1] = temp moves the value in temp variable to the last position of the sortArray. As we know that the value of temp= 10. So this element 10 of the sortArray is positioned at SORT_ARR_SIZE-1 position of sortArray which is 4-1 = 3-th index of sortArray. This simply means that 10 is moved to the last position of sortArray.
So now the final sortArray becomes: 40,20,30,10 as the first and last element of the array are swapped using above function SwapArrayEnds().
The program along with the output is attached in screenshot.
Functions are collection of codes or instructions merged together to act as one.
The function, where comments are used to explain each line is as follows:
//This defines the function
void SwapArrayEnds(int sortArray[],int SORT_ARR_SIZE){
//This increments the array element at index 0
sortArray[0] += sortArray[SORT_ARR_SIZE-1];
//This replaces the last element with the first
sortArray[SORT_ARR_SIZE-1]= sortArray[0]- sortArray[SORT_ARR_SIZE-1];
//This replaces the first element with the last
sortArray[0]= sortArray[0]- sortArray[SORT_ARR_SIZE-1];
}
At the end of the function, the first and the last elements of the array are swapped.
