Answer:

Computer hardware is any physical device used in or with your machine, whereas software is a collection of code installed onto your computer's hard drive. For example, the computer monitor you are using to read this text and the mouse you are using to navigate this web page are computer hardware.

All software utilizes at least one hardware device to operate. For example, a video game, which is software, uses the computer processor (CPU), memory (RAM), hard drive, and video card to run. Word processing software uses the computer processor, memory, and hard drive to create and save documents.

(c) [tex]\left \{\epsilon \right \}[/tex]

(d) [tex]\left \{\right \}=\phi[/tex]

Explanation:

The formal description of the given sets are as follows :-

a) The set containing the numbers 5, 9, and 27.

[tex]=\left \{ 5,\,9,\,27 \right \}[/tex]

(b) The set that contains all the natural numbers less than 2.

[tex]\left \{ x\ : X\varepsilon\mathbb{N} \right \text{and}\ x<2\}= \left \{1 \right \}[/tex]

(c) The set containing the empty string.

We know that in formal description, the empty string is denoted with [tex]\epsilon[/tex].

Thus, the required set : [tex]\left \{\epsilon \right \}[/tex]

(d) The set containing nothing at all.

[tex]\left \{ \right \}=\phi[/tex]

Answer:

Class A network 100.0.0.0/8, we need to divide it so that it can use 11 department, therefore 2^{4} = 16 maximum subnet. The subnet mask 255.240.0.0/12. The hosts per subnet are 2^20 = 1048574. The first 5 subnet range is attached with this question.

Explanation:

The IP address is 32 bits, The default subnet of class A is 255.0.0.0/8, but in this case we take 4 bits from host and add it to network bits so 8+4 = 12, that's why mask bit is 12.

8 bits   + 8 bits  +  8 bits  + 8 bits

100       .    0       .     0       .      0

we take 4 bits from 2nd octet so that it can use in 11 departments, so the remaining  4 bits + 8 bits + 8 bits = 20 bits

2^{20} = 1048574 hosts in each subnet

2^ {4} = 16 subnet ( 0 to 15 range)

when we subtract 255-15 = 240 so that the subnet mask is 255.240.0.0 / 12

Both Java servlets and CGI are utilized for generating dynamic web statements that admit a user application, process it on the server side and deliver answers to the user.

Servlets maintain various abilities that are challenging or difficult to achieve with conventional CGI. These abilities incorporate speaking directly to the network server,  sending data within various servlets, assembly tracking and maintaining of premature calculations.

Since servlets are composed in the Java programming dialect and develop a conventional API, so a servlet can be transferred from among web server. On the other hand, CGI programs may be principles subordinate, need to be recompiled or web server dependent.

#include<iostream>

using namespace std;

int main(){

   int x1,x2,x3;

   int y1,y2,y3;

   cout<<"Enter the value of first point(x1,y1): ";

   cin>>x1>>y1;

   cout<<"\nEnter the value of second point(x2,y2): ";

   cin>>x2>>y2;

   cout<<"\nEnter the value of third point(x3,y3): ";

   cin>>x3>>y3;

}

Explanation:

first include the library iostream for use the input/output commands

then, write the main function. within the main function declare the variable which store the value of points.

after that, use the 'cout' for output. It has the function which print the value or message on the screen.

and 'cin' is used to store the value in the variable.

So, in the above code cout ask for enter the value of point and after enter value by user, cin store in the variables.

Note: you have to enter two value with space or by enter.

The correct answer is option (d), which states that the percentile rank indicates what percentage of individuals in the sample scored below the target individual.

The percentile rank is a statistical measure that indicates the value below which a given percentage of observations in a group of observations falls. For example, to find the 90th percentile, you would identify the score k where 90 percent of the scores are the same as or below k, and 10 percent are above it. This means if you are at the 90th percentile in test scores, you scored better than 90 percent of the other test takers.

Interpreting percentiles is essential as it gives us information about the relative standing of an individual within a distribution. It is not a reflection of the actual score but instead a comparison with others' scores. Choice (d) is the correct answer to the question because the percentile rank tells us what percentage of individuals in the sample scored below the target individual.

Therefore the inverse function of  [tex]f(x)=1+\sqrt{1+2x}[/tex] is [tex]\frac{x^2-2x}{2}[/tex]

Explanation:

We need to find the inverse of function [tex]f(x)=1+\sqrt{1+2x}[/tex]

Function Inverse definition :

[tex]\mathrm{If\:a\:function\:f\left(x\right)\:is\:mapping\:x\:to\:y,\:then\:the\:inverse\:functionof\:f\left(x\right)\:maps\:y\:back\:to\:x.}[/tex]

[tex]y=1+\sqrt{1+2x}[/tex][tex]\mathrm{Interchange\:the\:variables}\:x\:\mathrm{and}\:y[/tex]

[tex]x=1+\sqrt{1+2y}[/tex]

[tex]\mathrm{Solve}\:x=1+\sqrt{1+2y}\:\mathrm{for}\:y[/tex]

[tex]\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}[/tex]

[tex]1+\sqrt{1+2y}-1=x-1[/tex]

Simplify

[tex]\sqrt{1+2y}=x-1[/tex]

[tex]\mathrm{Square\:both\:sides}[/tex]

[tex]\left(\sqrt{1+2y}\right)^2=\left(x-1\right)^2[/tex]

[tex]\mathrm{Expand\:}\left(\sqrt{1+2y}\right)^2:\quad 1+2y[/tex]

[tex]\mathrm{Expand\:}\left(x-1\right)^2:\quad x^2-2x+1[/tex]

[tex]1+2y=x^2-2x+1[/tex]

[tex]\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}[/tex]

[tex]1+2y-1=x^2-2x+1-1[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]2y=x^2-2x[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]

[tex]\frac{2y}{2}=\frac{x^2}{2}-\frac{2x}{2}[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]y=\frac{x^2-2x}{2}[/tex]

Therefore the inverse function of [tex]f(x)=1+\sqrt{1+2x}[/tex] is [tex]\frac{x^2-2x}{2}[/tex]

The answer is the second option "false." ISDN does not stand for Internet Services Dynamic Network it stands for Integrated Services Digital Network. ISDN is the international communication center for sending data, video, and voice over telephone wires.

Hope this helps.

Final answer:

ISDN stands for Integrated Services Digital Network. It is a set of communication standards that enables the transmission of voice, data, video, and other digital communication services over traditional telephone lines.

Explanation:

ISDN stands for Integrated Services Digital Network. It is a set of communication standards that enables the transmission of voice, data, video, and other digital communication services over traditional telephone lines. ISDN provides faster and more reliable internet connections compared to dial-up or analog connections.

ISDN utilizes digital signals and can carry multiple channels of data simultaneously. It offers a variety of services such as voice calls, video conferences, and data transfers. In contrast, dynamic networks are networks that can adapt and change their configuration dynamically based on various factors such as network traffic or device availability. The term 'Internet Services Dynamic Network' does not accurately represent the acronym 'ISDN.'

Answer:

By having personal health records available on a computer, more doctors have access to an individual's information. This allows doctors to view all prescriptions that a person is on, which can help protect patients from conflicting medications to be taken at once, and can save time if a patient doesn't have to redo tests and procedures because the doctor doesn't have the records.

Answer:

toString is right Answer

Explanation:

If you want to represent any object as a string, toString() method comes into existence.  

The toString() method returns the string representation of the object.

If you print any object, java compiler internally invokes the toString() method on the object. So overriding the toString() method, returns the desired output, it can be the state of an object etc. depends on your implementation.

Final answer:

The encryption tool that enables right-click encryption of files and folders is the Encrypting File System (EFS). It integrates with the Windows file system to protect sensitive data through encryption.

Explanation:

The encryption tool that allows users to encrypt files and folders by simply right-clicking a given object and setting a few options is the Encrypting File System (EFS). When you use EFS, which is a feature available in some versions of the Windows operating system, you can easily encrypt your files and folders to protect sensitive data.

EFS integrates with the file system to provide this seamless encryption process. Other options like BitLocker are used to encrypt entire drives, and PowerShell is a task automation framework, not specifically an encryption tool.

TPM is a hardware-based security feature to store cryptographic keys and does not directly allow users to encrypt files and folders by right-clicking.

The program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient is corresponds to the ingredients mentioned above.

Python is a general-purpose programming language. We want to write a python program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient.

48 cookies = 1.5 cups of sugar + 1 cup of butter + 2.75 cups of flour, so:

def main():

   cookies = float(input("How many cookies would you like to make?\n>"))

   sugar = (1.5 * cookies) / 48.0

   butter = cookies / 48

   flour = (2.75 * cookies) / 48

   print("To make ", cookies, " cookies, you will need:\n", \

         format(sugar, '.2f'), " cups of sugar\n", \

         format(butter, '.2f'), " cups of butter\n", \

         format(flour, '.2f'), " cups of flour", sep='')

   redoQuery()  

def redoQuery():

   yn = input("Would you like to check another batch size? (y/n)\n>")

   if yn == 'y':

       main()

   elif yn =='n':

       exit()

   else:

       print("Please enter only a lowercase \'y\' or lowercase \'n\'," \

             "then press enter")

       redoQuery()

main()

Explanation:

Offshore outsourcing occurs in companies when these transfer or delegate certain roles or responsibilities to other companies abroad. This business strategy is closely related to the use of information and communication technologies or telecommunication systems as it is through these, the main company can conduct its operations in a different region or country.

Due to the development of telecommunications, during the last years outsourcing has become quite popular as nowadays the multiple technologies allow companies to communicate with people all around the world, send documents and papers, create meetings, and other functions that are necessary for companies. Therefore, the statement that is true about offshore outsourcing is "Improved telecommunication systems have increased its attractiveness".

First of all, we will need a function that checks if a number is prime or not:

boolean isPrime(int n){

 for(int i=2; i<=math.sqrt(n); i++){

   if(n % i == 0) return false;

 }

 return true;

}

Then, in the main program, we will call this function with all the desired inputs, and we will print the prime numbers:

for(int n=100; n<= 1000; n++){

 if(isPrime(n)) print(n);

}
