computer processing unit

computer processing unit is a network computer that processes requests from a client server​.

The main element and "control center" of a computer is the Central Processing Unit (CPU). The CPU, sometimes known as the "central" or "main" processor, is a sophisticated collection of electronic circuitry that manages the device's software and operating system.

A central processing unit, sometimes known as a CPU, is a piece of electronic equipment that executes commands from software, enabling a computer or other device to carry out its functions.

Computers use a brain to process information, much like people do. The brain is the central processing unit for a computer (CPU). The CPU is the component that carries out all of the computer's instructions. It connects with all the other hardware parts of the computer while being on the motherboard.

Thus, computer processing unit.

Answer:

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

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.

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.

Explanation:Algorithms are aimed at optimizing everything. They can save lives, make things easier and conquer chaos. Still, experts worry they can also put too much control in the hands of corporations and governments, perpetuate bias, create filter bubbles, cut choices, creativity and serendipity, and could result in greater unemploymen

Answer: The algorithm must have an infinite number of steps because there are an infinite number of integers greater than one. It will run forever trying to count to infinity. Every algorithm must reach some operation that tells it to stop.

WooW We Have To All This Which Class can you Please tell

Answer:

The first step of learning about spreadsheets is understanding the terminology you will encounter as you work through this lesson. The glossary below lists terms that are specific to spreadsheet applications. Terminology that we learned when we looked at wordprocessing (such as copy, paste, clipboard, etc.) also apply to spreadsheet applications.

i. Number of parameters

ii. Type of parameters

When there are two or more constructors, definitely with the same name, in a given class, then the constructors are said to be overloaded. An overloaded constructor appears declared many times in a class but each time with different number of parameters and/or type of parameters.

For example, given a class Test, the following combination of constructors can exist;

i. public Test(int x){

 }

ii. public Test(String m){

  }

iii. public Test(int a, String b){

}

The following should be noted;

In the case of combination (i) and (ii), the constructors have the same number of parameters but different type of parameter. In other words, they both have 1 parameter but while the first one has a parameter type of int, the second has a parameter type of String.

In the case of combination (ii) and (iii), the constructors have different number of parameters and of course different type of parameters. In other words, the second constructor has 1 parameter of type String while the third constructor has 2 parameters of types int and String.

F = 13

Given:

x = false

y = 5

z = 1

F = (4%2)+2*Y +6/2 +(z&&x)

We solve this arithmetic using the order of precedence:

i. Solve the brackets first

=> (4 % 2)

This means 4 modulus 2. This is the result of the remainder when 4 is divided by 2. Since there is no remainder when 4 is divided by 2, then

4 % 2 = 0

=> (z && x)

This means (1 && false). This is the result of using the AND operator. Remember that && means AND operator. This will return false (or 0) if one or both operands are false. It will return true (or 1) if both operands are true.

In this case since the right operand is a false, the result will be 0. i.e

(z && x) = (1 && false) = 0

ii. Solve either the multiplication or division next whichever one comes first.

=> 2 * y

This means the product of 2 and y ( = 5). This will give;

2 * y = 2 * 5 = 10

=> 6 / 2

This means the quotient of 6 and 2. This will give;

6 / 2 = 3

iii. Now solve the addition by first substituting the values calculated earlier back into F.

F = (4%2)+2*Y +6/2 +(z&&x)

F = 0 + 10 + 3 + 0

F = 13

Therefore, the value of F is 13

Answer:

La electricidad es el conjunto de fenómenos físicos relacionados con la carga eléctrica y los campos eléctricos y también con el electromagnetismo. Dado que la energía eléctrica es una fuente importante de energía en la vida cotidiana, las palabras "electricidad" y "corriente" a menudo se usan indistintamente en el habla cotidiana. Sin embargo, la electricidad también incluye otros fenómenos fácilmente reconocibles como los rayos y la electricidad estática.

La electricidad tiene muchas aplicaciones técnicas. Por lo tanto, la ingeniería eléctrica se explora y se desarrolla más en la ingeniería eléctrica. A diferencia de muchos otros fenómenos físicos, muchos de los fenómenos asociados con la electricidad pueden medirse y calcularse previamente con gran precisión.

La electricidad es un fenómeno natural. La más conocida es la ocurrencia de rayos, que es causada por una diferencia de potencial en la atmósfera. Algunos peces, como la anguila eléctrica, también son capaces de generar electricidad. Además, los sistemas nerviosos animal y humano funcionan con señales eléctricas.

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();

 }
