Explanation:

Compiler – The compiler is the language processor, which reads the whole of your source software, and translates it into an equivalent program in the machine language.

Ex: C, C++, C#, Java.

When free of errors, the source code of a compiler is successfully transposed into the object code. At the end of the build, when the source code has errors, the compiler indicates the errors. Before the compiler can successfully recompile source code, errors must be removed.

Answer:

SSH, HTTPS and SMTP

Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Hence, SSH, HTTPS and SMTP are considered as secure network protocols.

HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).

SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Answer and Explanation:

Using MATLAB code:

Function Lkm = Lkm-mpgToLpkm (mpg)

Lkm= mpg*1.60934/3.78541;

Lkm= Lkm^(-1);

Lkm= Lkm*100;

%the code above defines a function Lkm and takes argument/input to its parameter mpg(miles per gallon) and then returns/output Lkm which is the litres per kilometers conversion from miles per gallon input.

end

To call the function written above with argument 30 mpg, we write:

Lkm= Lkm-mpgToLpkm (30)

Answer:

Acronis True Image is the one I would recommend out of these mentioned online backup services.

Explanation:

The evaluations and reviews of each of the online backup services are as follows:

a. iDrive

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 88% - very good

Features = 95% - excellent

Pricing = 85% - Very good

Because of its various features, pricing, and usability, IDrive reviews suggest that it is a very efficient online backup solution. However, there have been complaints concerning its speed and the fact that there are no monthly plans available.

b. Carbonite

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 87% - very good

Pricing = 85% - very good

File backup and restoration = 75% - good

Carbonite reviews reveal that it is simple to use and provides limitless backup for one device. The main drawback is that it has extremely poor backup speeds.

c. Acronis True Image

This is fast, simple and intuitive

It has complete control over the backup updates, including how and when they occur.

It is not expensive.

Acrnonis True image is a powerful backup storage service. It enables data and file backup and restoration from USB drives.

Many reviewers of Acrnonis True image have stated that they have had no issues with its service, that it is worth purchasing, and that there are no concerns.

d. Backblaze

Privacy = 70% - decent

Pricing = 100% - excellent

Support = 95% - excellent

Features = 65% - decent

File back-up and restoration = 70% - decent

Backblaze is one of the most popular internet backup services. This storage service, however, does not allow for ustomization.

Recommendation

Acronis True Image is the one I would recommend out of these mentioned online backup services. This is due to the fact that it delivers a large amount of accurate and high-quality data storage. It is quick, simple and intuitive, which is what most people care about. Furthermore, reviewers have stated that this service is quite effective and that there have been very few issues with it. The other services demonstrate that their services have flaws, such as lack of customization and slowness.

You can use thermal paste, active heat sink, liquid pipes, and even a fan. These are just some that I've heard.

Explanation:

All of these are cooling and will stop the Central Processing Unit from overheating.

Hope this helps :)

When rebuilding your computer, the cooling systems which would most efficiently remove heat from the Central processing unit (CPU) are: cooling fan and thermal compounds.

A computer refers to an intelligent electronic device that is designed and developed to receive raw data as an input and then processes these data into an information (output) that is usable by an end user.

Basically, the main part of a computer are broadly divided into the following;

A cooling device can be defined as a device that is designed and developed to efficiently remove or dissipate heat from the inside of a computer. The cooing system used in a computer are grouped into two

(2) main categories and these are:

I. Active cooling device: an example is a cooling fan.

II. Passive cooling device: an example is a heat sink.

In conclusion, the cooling systems which would most efficiently remove heat from the Central processing unit (CPU) are cooling fan and thermal compounds.

C15H24O

Explanation:

n(C) = 4.497 g/44g/mol = 0.1022

Mass of C = 0.1022 × 12 = 1.226 g

n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles

Mass of H = 0.0823 × 2 ×1 = 0.165g

Mass of O= 1.501 -(1.226 + 0.165)

Mass of O= 0.11 g

Number of moles of O = 0.11g/16g/mol = 0.0069 moles

Dividing through by the lowest ratio;

0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069

Answer:

The java program is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 Random r = new Random();

 int x, y;

 x = input.nextInt();  

 y = input.nextInt();

 int[][] Array2D = new int[x][y];

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          Array2D[i][j] = r.nextInt(9) + 1;      }

 }

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

 for(int i = 0; i < x ; i++){

     for(int j = 1; j < y; j+=2){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

}

}

Explanation:

This creates a random object

 Random r = new Random();

This declares x and y as integers

 int x, y;

This gets input for x

 x = input.nextInt();  

This gets input for y

 y = input.nextInt();

This declares the 2D array

 int[][] Array2D = new int[x][y];

The following iteration populates the array with integers 1 to 9

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          Array2D[i][j] = r.nextInt(9) + 1;      }

 }

The following iteration prints all elements of the array

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

The following iteration prints all elements on the even column

 for(int i = 0; i < x ; i++){

     for(int j = 1; j < y; j+=2){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

price = widget * 9.9

tax = price * 0.55

ship = price * 0.40

totalprice = price + tax + ship

print("Total Price: $",totalprice)

Explanation:

The question is incomplete, as what is required is not stated.

However, I will write convert the pseudocode to a programming language (in Python)

Get the number of widgets

widget = int(input("Widgets: "))

Calculate price

price = widget * 9.9

Calculate the tax

tax = price * 0.55

Calculate the shipping price

ship = price * 0.40

Calculate the total price

totalprice = price + tax + ship

Print the calculated total price

print("Total Price: $",totalprice)

Answer:

Select SUM(HOURS), SUM(CHARGES) from employees

Explanation:

The table structure is not given. So, I will assume that the table name is "employees", the columns to retrieve are "hours" and "charges"

Having said that, the function to retrieve the total of column is the sum() function.

So, the query is as follows:

Select ----> This means that the query is to retrieve from the table

SUM(HOURS), SUM(CHARGES) --- This represent the records to retrieve

from employees ---- This represents the table to retrieve from.
