Answer:
Database
Explanation:
A website or web application is a page or a collection of pages addressing the same information on the internet. Web pages and the whole web application is made by a web developer using tools like HTML, CSS, Javascript, Flask, react.js, etc.
All websites or applications require a fast, flexible but secure source of storage to hold information. This storage is called a database. Examples of databases are relational and non-relational databases.
Write an if-else statement for the following:
If user_tickets is less than 5, assign 1 to num_tickets. Else, assign user_tickets to num_tickets.
In python 3.8:
if user_tickets < 5:
num_tickets = 1
else:
num_tickets = user_tickets
For this code to work properly, you'll have to first declare user_tickets before the if-else statements.
What is the most vulnerable information that should be protected to prevent unauthorized access to your online files and records?
Answer:
Your user ID and password.
Explanation:
The user Id and password must be protected because when it is exposed to a third party then they can get access to information, data, to things they are not supposed to.
The user Id and password is provided as an authentication measure for one to be able to gain access to a computer system, network or files. It is what grants access to online files and record as it is the case here. It has to be protected for the sake of privacy.

salvado has a flash disk of 1.5GB and wants to store more music files of 950KBs each . How many files will he be able to store on his flash disk?
Answer:
Convert 1.5GB to KBs = 1500000kb
1500000kb/950kb ≈ 1579
Explanation:
A flash disk is a storage device. It has enough memory to store large files. In the given question, the flash disk has a memory of 1.5GB and can store 1578.94 music files of 950KBs each.
What is flash disk?A flash disk is a data storage device that uses flash memory specifically : a small rectangular device which is designed to be plugged directly into a USB port on a computer. It is often used for transferring files from one computer to another computer system.
Flash disks have no mechanical platters or access arms. It is termed "disk" because of the data which are accessed as if they were on a hard drive. The disk storage structure is emulated.
In the given question, the flash disk contains 1.5GB memory and has to store music files of 950KBs each. For determining the number of music files which can be stored in the flash disks, we have to first convert the unit of flash disk from GB to KB:
1GB = 1,000,000 KB
1.5 GB = 1,500,000 KB
size of music file = 950 KB
Number of music files that can be stored = storage in the flash disk ÷ size of the music file
Number of music files = 1500000KB ÷ 950KB
Number of music files = 1578.94

What is an example of an absolute cell reference? 52% D2 $B$5 !90!
Answer:
$B$5 is an example of absolute cell reference
Explanation:
There are two types of referencing in MS Excel.
1. Relative
2. Absolute
Relative cell referencing changes according to the corresponding new cells when it is copied in other cells. MS Excel uses relative cell referencing by default.
Absolute cell referencing uses dollar sign with the row number and column name. When any formula with absolute referencing is copied, the cell addresses used remain the same.
From the given choices in question,
$B$5 is an example of absolute cell reference
An example of an absolute cell reference is "$B$5".
Thus, option (C) is correct.
Cell references can be either relative or absolute.
A relative cell reference changes when it is copied to another cell.
For example, if you have a formula in cell C2 that references cell A2 as "=A2+1", and you copy this formula to cell C3, it will automatically adjust to "=A3+1".
An absolute cell reference remains constant, regardless of where it is copied. When a cell reference is made absolute, the dollar sign ($) is used to indicate this.
For example, if you have a formula in cell C2 that references cell B5 as "=B$5+1", and you copy this formula to cell D3, it will still refer to cell B5 as "=B$5+1". The row and column references remain fixed.
Therefore, "$B$5" is an absolute cell reference.
Thus, option (C) is correct.

Write a JavaScript script that has subprograms nested three deep and in which each nested subprogram references variables defined in all of its enclosing subprograms.
Answer and Explanation:
Subprograms are nested three deep hence we would have three subprograms/functions under one program(function)
We call the program/function MotherFunction( using camel case variable naming rules)
function MotherFunction() {
var mother= 8;
console.log(mother);
function subDaughter1() {
var subDaughter1X = mother + 12;
console.log(subDaughter1X);
function subDaughter2() {
var subDaughter2X= mother + 5;
console.log(subDaughter2X);
function subDaughter3() {
var subDaughter3X= mother + 3;
console.log(subDaughter3X);
alert("sum="+subDaughter1X+subDaughter2X+subDaughter3X);
}
}
}
}
MotherFunction();
We created the first function and nested subfunctions under it, adding up the variable from the parent function(mother function) to its subfunctions and then alerting the total value of all the subfunction variables summed in the last/third subfunction. We then called the function after defining it.

If after a call to fork, we want any updates to memory by the parent process to be visible to the child process, and vice-versa, what flag should be included in the fourth argument of mmap?
Answer:
MAP_SHARED
Explanation:
The MAP_SHARED should be included in the 4th argument of map. When we have a MAP_SHARED set, then we have it that it is preserved across a fork2 system call.
It is visible immediately in every parent, siblings or child processes. This is to say that any change that is made to this mapping is immediately seen by readers.
Based on the data definition classes identified below, assume you wish to create a Dictionary class that inherits from the Book class. In addition to title and cost, the Dictionary class must also store the number of words present in the dictionary. Write the code that will create a constructor in the dictionary class that passes in and sets the dictionary's title, cost, and number of words.
public class Book {
private String title;
private double cost;
public Book(String title) {
this(title, 0.00);
}
public Book(String title, double cost) {
this.title = title;
this.cost = cost;
}
public String getTitle() { return this.title; }
public double getCost() { return this.cost; }
}
public class Dictionary extends Book {
private double numWords;
// Create Contructor
}
//==============================
// Book class
//==============================
public class Book {
private String title;
private double cost;
public Book(String title) {
this(title, 0.00);
}
public Book(String title, double cost) {
this.title = title;
this.cost = cost;
}
public String getTitle() {
return this.title;
}
public double getCost() {
return this.cost;
}
}
//==============================
// Dictionary class
//==============================
public class Dictionary extends Book {
private double numWords;
// Create Contructor
public Dictionary(String title, double cost, double numWords){
super(title, cost);
this.numWords = numWords;
}
}
Explanation:The actual response to this question is shown in bold face in the above.
Line 1:
public Dictionary(String title, double cost, double numWords){
Here the header for the constructor for the Dictionary class is written which takes in three parameters - title, cost and numWords. These parameters will be used to set the values of the instance variables of the Dictionary class.
Remember that the Dictionary class extends from the Book class. Therefore, in addition to its numWords attribute, the Dictionary class also has the title and cost attributes.
Line 2:
super(title, cost)
Here, since the Dictionary class inherits from the Book class, it can also call the constructor of Book class to initialize two of its three variables which are title and cost. Hence the need for the super() method keyword. In other words, the super() in the Dictionary class is the constructor from the parent class and it is used here to set the dictionary's title and cost attributes.
Line 3:
this.numWords = numWords;
Here, the only attribute left to be set is the numWords. Therefore, the 3rd line sets this attribute to the parameter passed into the constructor in line 1.
Line 4:
}
Here, the block containing the Dictionary class constructor is being closed.

Assume a file containing a series of integers is named numbers.txt and exists on the computer’s disk. Write a program that calculates the average of all the numbers stored in the file.
Answer:
Explanation:
The following code is written in Java. It assumes that the numbers.txt file is in the same folder as the Java file and the numbers are separated one on each line. It reads the file, adds all the numbers to an array, then adds the numbers into a single variable and finally divides by the total amount of numbers in order to get the average.
public static void main(String[] args) {
ArrayList<Integer> numbers = new ArrayList();
try {
File myObj = new File("numbers.txt");
Scanner myReader = new Scanner(myObj);
while (myReader.hasNextLine()) {
String data = myReader.nextLine();
numbers.add(Integer.parseInt(data));
}
myReader.close();
} catch (FileNotFoundException e) {
System.out.println("An error occurred.");
e.printStackTrace();
}
int average = 0;
for (int x:numbers) {
average += x;
}
average = average / numbers.size();
System.out.println(average);

When the body of a function is implemented temporarily with just a printf call that displays a message reporting that the function was entered, the programmer is using __________.
Answer:
The answer is "a stub".
Explanation:
A stub seems to be the feature only with expected signatures, that is a name and agreed arguments, however, the execution is incomplete. This function is used as a set, which allows the code to be evaluated before another method call is fully written. This method used in the development of software is a type of hardware, which is used to support certain programming functions.

Answer:
A mechanical computer uses moving parts to do it’s calculations. Think old style adding machines.Electronic computers use electronic oscillators to generate a clock. The oscillator might include a mechanical element such as a crystal, but the majority of the clock signal is processed in the electrical domain.
Explanation:
An example of a mechanical computer clock is a Swiss watch movement, which needs no electronics. Movement is based upon springs coupled to other mechanical pieces. Swiss watches are high precision mechanical computers that do counting. There are other types of more sophisticated mechanical computers. Research the works of Konrad Zuse and his Z1 mechanical computer.

Write a program that reads one or more strings from the standard input and outputs the count of vowels, consonants, and digit characters found in the stream.
Answer:
endinput = "no"
mylist = []
vowel = ['a', 'e', 'i', 'o', 'u']
vowelcount = 0
consonantcount = 0
digitcount = 0
string = " "
number = [ str(i) for i in range(0, 10)]
while endinput == "no":
inputs = input("Enter string value: ")
mylist.append(inputs)
endinput = input("Do you want to end input? ( enter no to continue: ")
for item in mylist:
txt = item
print(txt)
for i in txt:
if i == string:
continue
elif i in vowel:
vowelcount +=1
elif i in number:
digitcount += 1
else:
consonantcount += 1
print("Vowels: ", vowelcount)
print("Digits: ", digitcount)
print("Consonant: ", consonantcount)
Explanation:
The python program receives one or more strings from the standard input and appends it to a list. The algorithm iterates through the list of string values and counts the number of vowels, consonants, and digits.
How long will it take to transfer 1GB data on USB 2.0, on USB 3.0
Answer:
Have a great day, Here is the answer to your question:
It will take around 18 seconds
Explanation:
So in principle 1GB of data to be uploaded running at peak speed is suggested to take around 18 seconds but in fact, DCD test results show USB 2.0 takes 3 minutes 18 seconds to complete a 1GB switch. Whereas USB 3.0 can accommodate up to 5gbps of data transferred-more than 10 times faster than its predecessor.
Let g(x) = cos(x/2) - 3x. Let f(x) = 2x + 5. What is g(f(x))?
Answer:
f = 2
Explanation:
g(x) = cos(x/2) - 3x=w where w=-3.5 or -1 or -38.5
13– (13/2)-3*13=-3.5 (1st d value of g(x))
-1-(-1/2)-3*(-1)=-1 (the 2nd possible value)
g(x) = cos(x/2) - 3x=-1 where the first x=13 and the 2nd one=-1
where the first x=-1 and the 2nd one=-38.5 (the 3rd value)
g(x) = cos(x/2) - 3x)=0 where cos(x/2=-3.5
g(f(x)) = cos(f(x)/2) - 3 aka 0.5 f(x) = cos(2x+5 aka 7x) (x/2 - 3 =aka -1 );
(2x+5) = 7x by definition but the equation has to be set to 7 to find x)
(7x/2 -6x=0) -7 on both sides
x/2–6x=-7
x/2= 13
26/2=x
x=13 (these values are set up for 2x+5=7.
13-(-7)=-7
13-6+-1=-7
the 2nd x=-1
gfx=cos*2*x i.e cos*2*13 or cos*2*-1
cos*2*13=26
cos*2*(-1)=-1
cos=1
(cos*2*13)=the 1st gfx value=26 basically.
( cos*2*(-13)=-26 (the 2nd gfx value)
cos*2*(-1)=-`1 (the 3rd gfx value)
f=2
hope this helped!
