who invented pascaline and when?​

Answer:

The SQL queries are as follows:

1. select * from customer

select * from sale

select * from product

2. select name, sex from customer

3. select * from customer where sex = 'male'

4. select name, age from customer where sex = 'male'

5. select name, price, color from product

Explanation:

Given

Tables: customer, sale, product

Required

Answer question 1 to 5

(1) All data in the given tables

To do this, we make use of the select clause to retrieve data from each of the table and * to select all data.

So, we have:

select * from customer --> This lists all data from customer table

select * from sale --> This lists all data from sale table

select * from product --> This lists all data from product table

(2) Selected details from customer table

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, sex from customer

(3) Male customers

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve male customers, we introduce the where clause

So, we have:

select * from customer where sex = 'male'

(4) Name and age of male customers

In (3), we have:

select * from customer where sex = 'male'

To retrieve the name and age, we replace * with name and age. So, we have:

select name, age from customer where sex = 'male'

(5) Name, price and color of products

In (1), we have:

select * from product --> This lists all data from product table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, price, color from product

Answer:

The base case

Explanation:

Required

The part that determines the termination of a recursion

This part of a recursion is referred to as the base case.

Take for instance, the following:

factorial(int n) {

   if (n < = 1) {         return 1; }

   else {             return n*factorial(n-1);    }  }

The base case of the above is     if (n < = 1) {         return 1; }

Because the recursion will continue to be executed until the condition is true i.e. n less than or equals 1

Explanation:

If the HDD is spinning, this means that the power cable is correctly connected and that the drive is receiving power and powering on. However, this does not mean that the HDD is functioning correctly and reading the information. Therefore, the next logical step would be to check the SATA cable that connects the drive to the motherboard. The cable may be broken or maybe the SATA slot on the motherboard. Switch out the cables and plug it into another slot. If this does not work, then it may be that the HDD is broken. Multiple Beeps can also mean that the RAM or CPU is not plugged in correctly or broken.

Las computadoras que existian en el inicio de la informatica y las que existen ahora tenian los mismos componentes. Estos eran CPU, Placa Madre, RAM, HDD, y tarjeta grafica. Lo que si cambio fueron el velocidad y capacidad. Por ejemplo, en el inicio las Tarjetas de RAM venian como DDR a una velocidad maxima de 133 Mhz con una capacidad de entre 4mb y 8mb. Hoy en dia tenes RAM de DDR5 con una velocidad de 4400 Mhz y de 8gb. Mientras que avanzaba el tiempo los componentes de las computadoras aumentaban en velocidad y capacidad aunque el tamaño bajaba o aumentaba dependiendo del gusto del usario.

Answer:

The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:

Sign (1 bit) = 0 (a positive number)

Exponent (8 bits) = 0111 1100

Mantissa (23 bits) = 000 0000 0000 0000 0000 0000

Explanation:

1. First, convert to the binary (base 2) the integer part: 0.

Divide the number repeatedly by 2.

Keep track of each remainder.

We stop when we get a quotient that is equal to zero.

division = quotient + remainder;

0 ÷ 2 = 0 + 0;

2. Construct the base 2 representation of the integer part of the number.

Take all the remainders starting from the bottom of the list constructed above.

0(10) = 0(2)

3. Convert to the binary (base 2) the fractional part: 0.125.

Multiply it repeatedly by 2.

Keep track of each integer part of the results.

Stop when we get a fractional part that is equal to zero.

#) multiplying = integer + fractional part;

1) 0.125 × 2 = 0 + 0.25;

2) 0.25 × 2 = 0 + 0.5;

3) 0.5 × 2 = 1 + 0;

4. Construct the base 2 representation of the fractional part of the number.

Take all the integer parts of the multiplying operations, starting from the top of the constructed list above:

0.125(10) =

0.001(2)

5. Positive number before normalization:

0.125(10) =

0.001(2)

6. Normalize the binary representation of the number.

Shift the decimal mark 3 positions to the right so that only one non zero digit remains to the left of it:

0.125(10) =

0.001(2) =

0.001(2) × 20 =

1(2) × 2-3

7. Up to this moment, there are the following elements that would feed into the 32 bit single precision IEEE 754 binary floating point representation:

Sign: 0 (a positive number)

Exponent (unadjusted): -3

Mantissa (not normalized):  1

8. Adjust the exponent.

Use the 8 bit excess/bias notation:

Exponent (adjusted) =

Exponent (unadjusted) + 2(8-1) - 1 =

-3 + 2(8-1) - 1 =

(-3 + 127)(10) =

124(10)

9. Convert the adjusted exponent from the decimal (base 10) to 8 bit binary.

Use the same technique of repeatedly dividing by 2:

division = quotient + remainder;

124 ÷ 2 = 62 + 0;

62 ÷ 2 = 31 + 0;

31 ÷ 2 = 15 + 1;

15 ÷ 2 = 7 + 1;

7 ÷ 2 = 3 + 1;

3 ÷ 2 = 1 + 1;

1 ÷ 2 = 0 + 1;

10. Construct the base 2 representation of the adjusted exponent.

Take all the remainders starting from the bottom of the list constructed above:

Exponent (adjusted) =

124(10) =

0111 1100(2)

11. Normalize the mantissa.

a) Remove the leading (the leftmost) bit, since it's allways 1, and the decimal point, if the case.

b) Adjust its length to 23 bits, by adding the necessary number of zeros to the right.

Mantissa (normalized) =

1 000 0000 0000 0000 0000 0000 =

000 0000 0000 0000 0000 0000

12. The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:

Sign (1 bit) = 0 (a positive number)

Exponent (8 bits) = 0111 1100

Mantissa (23 bits) = 000 0000 0000 0000 0000 0000

Answer:

Pseudocode; flowchart.

Explanation:

Pseudocode uses English-like statements to outline the logic of a computer program. A pseudocode gives a summary of the steps adopted during a software development process using simple (concise) words and symbols.

A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.

Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).

Answer:

Following are the code to the given question:

#include<iostream>//header file

#include<math.h>//header file

using namespace std;

int main()//main method

{

   long long x, x1, y, y1;//defining long variable

   int count=0,i,j;//defining integer variable

   cout<<"Enter a range for x coordinates: "<<endl;//print message        

   cin>>x>>x1;//input x and x1 value                          

   cout<<"Enter a range for y coordinates: "<<endl;//print message

   cin>>y>>y1; //input y and y1 value  

   for(i = x; i <= -x1; i++)//use nested loop that tests each coordinates                                        

   {

       for(j = y; j <= y1; j++)//use nested loop that tests each coordinates

       {

           if(((2*pow(i,2)) + abs(2*i*j) + pow(j,2)) == 10000)//use if that checks condition as per the given question

           {

               cout<<"There is a planet at "<<i<<", "<<j<<endl;//  print coordinates

               count++;//incrementing count variable value                                                    

           }

       }

   }

   cout<<"Total number of planets detected are: "<<count<<endl;//print count value

   return 0;

}

Explanation:

In this code, inside the main method long "x, x1, y, and y1" and integer "count, i, and j" type variable is declared that uses a long variable to input value from the user-end.

In the next step, two nested loops have defined that test each coordinate and define if block that checks condition as per the given question and use i, j, and count variable to print value with the message.

Answer:

respond differently.

Explanation:

NIST is acronym for National Institute of Standards and Technology and it's under the U.S. Department of Commerce. The NIST cybersecurity framework (CSF) is a powerful tool that provide guidelines for both the external and internal stakeholders of organization on how they can effectively and efficiently organize, manage, and improve their cybersecurity programs, so as to mitigate the risks associated with cybersecurity.

The NIST SP 800 30 is a risk mitigation framework that provide guidance for conducting or allows scope for research, assessment and acknowledgement for risk mitigation of federal information systems and organizations.

Typically, NIST SP 800 30 is used for translating cyber risk so that it can easily be understood by the chief executive officer (CEO) and board of both a public and private organization.

An organization is expected to most likely respond differently to an internal user such as one of its employees that attempt to escalate his or privilege than to an external hacker.

This is usually so because the organization trust its internal users to an extent than it does with external users or an attacker such as an external hacker.

Answer:

Flex direction

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

Generally, all HTML documents are divided into two (2) main parts; body and head.

The head (header) contains information such as version of HTML, title of a page, metadata, link to custom favicons and cascaded style sheet (CSS) etc.

On the other hand, the body of a HTML document contains the contents or informations that a web page displays.

Generally, the part of a HTML document where the cascaded style sheet (CSS) file is linked is the header.

A style sheet can be linked to an HTML document by three (3) main methods and these are;

I. External style.

II. Inline style.

III. Embedded (internal) style.

Flex direction is a CSS property that's used to determine whether flex items are displayed horizontally or vertically.

Answer:

Screen resolution

Explanation:

The brightness of the words and pictures displayed on computer screen is referred to as screen resolution. Items seem crisper at larger resolutions, such as 1600 x 1200 pixels. They also seem smaller, allowing for more objects to be displayed on the screen. The greater the resolution supported by a display, the larger it is.

Phased-In-Phased-Out Conversion

Answer:

["apple", "banana", "cherry"]

Explanation:

In programming lists are defined by using square brackets. Curly brackets are used to define sets or dictionaries. Dictionaries are similar to lists but are not really considered lists since they use a key: value system unlike lists. Parenthesis in programming are used to define tuples or in some languages object literals with curly brackets inside. A list uses only square brackets, and depending on the language can either contain elements of the same type of different types. Therefore, the only correct example of a LIST in this question would be

["apple", "banana", "cherry"]

Answer:

The correct answer is "Consistency".

Answer: forwarding: move packets from router's input to appropriate router output

routing: determine route taken by packets from source to destination

Explanation:

The network layer refers to where connections take place in the internet communication process by sending packets of data between different networks.

The distinction between the forwarding function and the routing function performed in the network layer is that the forwarding function move packets from the input of the router to the appropriate router output while the routing function:m helps in knowing the routee taken by packets from the source to destination.

Answer:

The program in Java is as follows:

import java.util.*;

import java.lang.Math;

public class Rooter{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 int start;

 System.out.print("Start: ");

 start = input.nextInt();

 while(start<=0){

     System.out.print("Number must be positive\nStart: ");

     start = input.nextInt();  }

 while(start>=0){

     System.out.println(Math.sqrt(start));

     start--;  }

}

}

Explanation:

This declares start as integer

 int start;

This prompts the user for input

 System.out.print("Start: ");

This gets input for start

 start = input.nextInt();

The following is repeated until the user input is valid i.e. positive

 while(start<=0){

     System.out.print("Number must be positive\nStart: ");

     start = input.nextInt();  }

The following while loop prints the square root of each number till 0

 while(start>=0){

     System.out.println(Math.sqrt(start));

     start--;  }
