Answer:
Update the mouse device driver
Explanation:
In a situation where the operating system cannot communicate with a mouse the solution will be to Update the mouse device driver reason been that Mouse Driver is often and always needed to help the motherboard to interact with the device and It is also a software that works between the Operating System and the Mouse because It can effectively and efficiently translates the signals to the motherboard in an appropriate manner or ways which is why Microsoft’s generic drivers are enough and efficient for proper interaction between the Mouse and the Operating System.
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.

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)
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.

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. Implementing a site-to-site VPN for server access.B. Implementing a DMZ segment for the server.C. Implementing NAT addressing for the servers.D. Implementing a sandbox to contain the servers.
Answer:
Option A (Implementing a site-to-site VPN for server access) seems to be the correct choice.
Explanation:
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.

Write a function PrintShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". 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
printf("Too small"); //displays Too small message in output
printf("\n"); } //prints a new line
//the following else if part will execute when the above IF condition evaluates to //false and the value of bagOunces is greater than 10
else if (bagOunces > 10){
printf("Too large"); //displays the message: Too large in output
printf("\n"); //prints a new line }
/*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.

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).
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.
Write a method called listSearch() that takes in a target string and a list of other strings. This method returns a (possibly shorter) list containing all of the strings from the original list that themselves contain the target string you are searching for. Check for the target string as a case-sensitive substring of every member of the list. You can either modify the provided list or create a new one.
Answer:
public static List<String> listSearch(String searchFor, List<String> list){
List<String> foundList = new ArrayList<String>();
for(String s:list){
if(s.contains(searchFor)){
foundList.add(s);
}
}
return foundList;
}
Explanation:
Create a method named listSearch that takes two parameters, a String named searchFor and a String list named list
Inside the method, initialize a new String list named foundList, this will be used to hold the strings that contains the target string. Create a for loop that iterates through the list. Check if a string in the list contains the searchFor using the contains method. If it does, add the string to the foundList. When the loop is done, return the foundList.

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
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:

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. Implementing a site-to-site VPN for server access.
B. Implementing a DMZ segment for the server
C. Implementing NAT addressing for the servers
D. Implementing a sandbox to contain the servers
Answer:
(B) Implementing a DMZ segment for the servers
Explanation:
DMZ is the short form for Demilitarized Zone. It is the temporary storage between an internal or private LAN and the public Internet. The main purpose of the DMZ is to give additional layer of security to a company's LAN (Local Area Network).
Once there are services to be provided to users on the public Internet, such services should be added to the DMZ. A few services that are worth implementing a DMZ segment for are;
i. Email servers
ii. Web servers
iii. Proxy servers
iv. FTP servers

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]);
}

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.

Shovels and Shingles is a small construction company consisting of 12 computers that have Internet access. The company's biggest concern is that a wily competitor will send e-mail messages pretending to be from Shovels and Shingles in order to get confidential information. 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.

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
When a higher-priority thread enters the ready state, the operating system generally preempts the currently running thread (an operation known as preemptive scheduling). Depending on the operating system, a steady influx of higher-priority threads could postponeâ possibly indefinitelyâ the execution of lower-priority threads. such indefinite postponement is sometimes referred to more colorfully as________.
Answer:
starvation
Explanation:
An indefinite postponement is sometimes make reference to as more colorfully as starvation when a stable influx of preferential or higher-priority threads could postponeâ possibly indefinitelyâ the execution of lower-priority threads though depending on operation system
Operating systems employ a technique called aging to curb against or avoid starvation, when a thread waits in the ready state, the operating system moderately grow the thread’s priority to ensure that the thread will eventually run.
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

What is the value of the totalsString variable after the following code is executed? var totals = [141.95, 212.95, 411, 10.95]; totals[2] = 312.95; var totalsString = ""; for (var i = 0; i < totals.length; i++) { totalsString += totals[i] + "|"; }
141.95|212.95|312.95|10.95|
Explanation:Reformatting the code snippet and giving it line numbers;
1. var totals = [141.95, 212.95, 411, 10.95];
2. totals[2] = 312.95;
3. var totalsString = "";
4. for (var i = 0; i < totals.length; i++) {
5. totalsString += totals[i] + "|";
6. }
Line 1 creates an array called totals with four elements.
First element = totals[0] =141.95
Second element = totals[1] = 212.95
Third element = totals[2] = 411
Fourth element = totals[3] = 10.95
Line 2 replaces the value of the third element totals[2] = 411 with 312.95.
Therefore the array totals = [141.95, 212.95, 312.95, 10.95]
Line 3 creates an empty string called totalsString
Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length
totals.length = 4 (which is the number of items in the array totals)
This means that the loop cycles from i=0 to i<4
During cycle 1 when i = 0, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[0] + "|" //substitute the values
totalsString = "" + 141.95 + "|"
totalsString = 141.95|
During cycle 2 when i = 1, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[1] + "|" //substitute the values
totalsString = "141.95|" + 212.95 + "|"
totalsString = 141.95|212.95|
During cycle 3 when i = 2, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[2] + "|" //substitute the values
totalsString = "141.95|212.95|" + 312.95 + "|"
totalsString = 141.95|212.95|312.95|
During cycle 4 when i = 3, the expression inside the for loop executes as follows;
totalsString = totalsString + totals[3] + "|" //substitute the values
totalsString = "141.95|212.95|312.95|" + 10.95 + "|"
totalsString = 141.95|212.95|312.95|10.95|
At the end of the execution, totalsString = 141.95|212.95|312.95|10.95|
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.
What happens if two functions are defined with the same name, even if they are in different arguments within the same .py files?
Answer:
Following are the code to this question:
def data(a):#defining method data that accepts parameter
print (a)#print parameter value
def data(b):#defining method data that accepts parameter
print (b)#print parameter value
x=input("enter value: ")#defining variable x that5 input value from user
print(data(x))#call method data
Output:
enter value: hello..
hello..
None
Explanation:
As the above code, it is clear defines that python doesn't support the method overloading because More than one method can't be specified in a python class with the same name and python method arguments have no type. The single argument method may be named using an integer, a series, or a double value, that's why we can say that it is not allowed.In the context of structured systems analysis and design (SSAD) models, a _____ is a tool that illustrates the logical steps in a process but does not show data elements and associations.
