A square QR code contains 40×40 tiny squares (pixels) where each tiny square represents a 0 or a 1. Calculate how many bytes of data can be stored on the QR code​

Answers

Answer 1

Answer:

Explanation:

QR Codes are made of multiple rows and columns. The combination of these rows and columns makes a grid of modules (squares). There can be a maximum of 177 rows and 177 columns which means the maximum possible number of modules is 31,329. With the eye, these are just small squares and mean very little, but the exact arrangement of those modules allows the QR Code to encode its data. This means that, unlike traditional barcodes which are 1 dimensional and use 1 row of lines, QR Codes use 2 dimensions which allows them to store a lot more data in the same area of space.

Briefly explain purpose of input device​

Answers

Answer:

Mouse, Keyboard, Headphones, Mouse dongle.

Explanation:

Input Device Definition: A piece of equipment/hardware which helps us enter data into a computer is called an input device. For example keyboard, mouse, etc.

Answer:

Input devices are those devices connected to the computer which are used to enter the data. Input can be in the form of text, graphics and sound. There are different types of input devices for different types of inputs.

Explanation:Today, input devices are important because they are what allows you to interact with and add new information to a computer. For example, if a computer had no input devices, it could run by itself but there would be no way to change its settings, fix errors, or other various user interactions. Also, if you wanted to add new information to the computer (e.g., text, command, document, picture, etc.), you wouldn't be able to do so without an input device.

This program will output a right triangle based on user specified height triangleHeight and symbol triangleChar. It is strongly suggested to use the for loop for this solution.

(1) The given program outputs a fixed-height triangle using a * character. Modify the given program to output a right triangle that instead uses the user-specified triangleChar character.


(2) Modify the program to use a nested loop to output a right triangle of height triangleHeight. The first line will have one user-specified character, such as % or *. Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangleHeight. Output a space after each user-specified character, including after the line's last user-specified character.


Example output for triangleChar = % and triangleHeight = 5:


Enter a character:

%

Enter triangle height:

5


%

% %

% % %

% % % %

% % % % %


#include

< stdio.h >


int main(void) {

char triangleChar;

int triangleHeight;


printf("Enter a character:\n");

scanf("%c", &triangleChar);


printf("Enter triangle height:\n");

scanf("%d", &triangleHeight);

printf("\n");


printf("* \n");

printf("* * \n");

printf("* * * \n");


return 0;

}

Answers

The program illustrates the use of loops;

Loops are program statements that are used to perform repetition

The complete program

The modified program in C, is as follows:

#include<stdio.h>

int main(void) {

   char triangleChar; int triangleHeight;

   printf("Enter a character: ");    scanf("%c", &triangleChar);

   printf("Enter triangle height: ");    scanf("%d", &triangleHeight);

   for (int i = 0; i<triangleHeight; i++){

       printf("\n");

       for(int j = 0;j<=i;j++){

           printf("%c",triangleChar);

       }

   }

   return 0;

True or false, cases must use curly braces like other test condition statements
A. true
B. false

Answers

Answer:

False

Explanation:

You can use curly braces to scope everything that's inside of the case body, but they are not necessary.

There are cases where you will need explicit bodies for cases:

If you have two different cases that both contain a variable called 'x', you will need to scope one or both of the cases.

What is scoping?

Scoping in a language defines where variables can be accessed, or referenced.

int i = 0;

// First scope

{

int x = i + 10;

}

// Second scope

{

int j = x + 2;

}

Console.WriteLine(j);

There are a few errors in this code.

In the second scope, we try to use the variable 'x' which was defined in the first scope, but we can't find that variable because it is defined in a scope that cannot be reached by the second scope. The same goes with the Console.WriteLine(j); line, we try to access a variable that is not defined in the current scope, and is instead defined in a nested scope.

In most languages, scoping is essentially a stack, where the lower nested scopes can access variables defined in the previous scope, but not the other way around.

So now you know a little bit about scopes; when to use them in case bodies, and that you do not have to use a body for a case if it's not necessary.

Which loop structure always uses a semicolon after the test condition?

Explanation:

It could be B, but I'm going with A because of the fact that right after the condition, there is a semicolon, whereas for the do-while loop, the semicolon comes after the )

Syntax:

// For loop

for (int i = 0; i < 10; i++)

{

// Body

}

// Do-while

int i = 0;

do

{

i++;

// Other code

} while(i < 9); // We do i < 9, because by the time we get to the condition, i = 10, because the increment happens before the condition is checked

Answer:

do-while

Explanation:

syntax:

do {

} while(the condition is true);

In the other two types of loops, you can put a semicolon after the condition, but it signifies the end of the statement (e.g.  for loop, it will mean end of for statement and it's body will have no meaning)

a transmitter is operating at 150 MHz with a power of 3 W into a one-quarter wavelength vertical antenna. The receiver, which is 32.2 km away, has an antenna with a gain of 8 dB. What is the received power?

Answers

The received power will be 1.243 nW

We're given:

frequency [tex]f[/tex] = 150MHz

distance of the receiver [tex]d[/tex] = 32.2 km=32200m

Power of transmitter [tex]P_{t}[/tex] = 3W

Antenna gain = 8dB

To find :

Power received [tex]P_{r}[/tex]

[tex]P_{r}= \frac{P_{t} *G_{t}*G_{r}* \lambda^2 }{16*\pi^2*d^2}[/tex]

where [tex]G_{t[/tex] is transmit gain and [tex]G_{r[/tex] is receive gain as refrenced to isotropic source

⇒wavelength [tex]\lambda = \frac{c}{f}[/tex] where c is the speed of the light

⇒  [tex]\lambda = \frac{3*10^8}{150*10^6} =2m[/tex]

[tex]G_{t}= 1*1.64[/tex] ( value of [tex]dipole[/tex] = 1.64)

Now,

Antenna gain[tex]=8dB[/tex] ( in decibals)

⇒[tex]10log(x)=8[/tex]

⇒[tex]x=10^0^.^8=6.3095[/tex]

⇒ considering isotropic receiver

⇒[tex]G_{r}=6.3095*1.64=10.3477[/tex] ([tex]dipole[/tex] =1.64)

Now , using the formula

[tex]P_{r}= \frac{3 *1.64*10.3477 *2^2 }{16*\pi^2*32200^2}=1.2437*10^-^9[/tex]

Hence The received power will be 1.243 nW
