How do headphones work? (From pc)
____ [38]
<span>Large headphones are essentially just two loudspeakers mounted on a strap that clamps firmly over your head. Earbuds work the same way but, as you would expect, everything inside them (the magnet, the coil of wire, and the diaphragm cone that makes sound) is shrunk down to a much smaller size.</span>

Consider an error-free 64 kbps satellite channel used to send 512 byte data frames in one direction, with very short acknowledge
Vladimir [108]

Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes  

Propagation Time (t​​​​​​p ) =270 ms

Change Bandwidth  kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 =  4096 bits

Frame length = 4096 bits

Formula

Transmission time (T​​​​​​t) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (T​​​​​​t) = 4096 / 65536

Transmission time (T​​​​​​t)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

Kitty [74]

Answer:

Here the code is given as follows,

#include <stdio.h>

#include <stdlib.h>

union floatingPoint {

float floatNum;

double doubleNum;

long double longDoubleNum;

};

int main() {

union floatingPoint f;

printf("Enter data for type float: ");

scanf("%f", &f.floatNum);

printf("\nfloat %f ", f.floatNum);

printf("\ndouble %f ", f.doubleNum);

printf("\nlong double %Lf ", f.longDoubleNum);

printf("\n\nBreakdown in Hex");

printf("\nfloat in hex %x ", f.floatNum);

printf("\ndouble in hex %x ", f.doubleNum);

printf("\nlong double in hex %Lx ", f.longDoubleNum);

printf("\n\nEnter data for type double: ");

scanf("%lf", &f.doubleNum);

printf("float %f ", f.floatNum);

printf("\ndouble %f ", f.doubleNum);

printf("\nlong double %Lf ", f.longDoubleNum);

printf("\n\nBreakdown in Hex");

printf("\nfloat in hex %x ", f.floatNum);

printf("\ndouble in hex %x ", f.doubleNum);

printf("\nlong double in hex %Lx ", f.longDoubleNum);

printf("\n\nEnter data for type long double: ");

scanf("%Lf", &f.longDoubleNum);

printf("float %f ", f.floatNum);

printf("\ndouble %f ", f.doubleNum);

printf("\nlong double %Lf ", f.longDoubleNum);

printf("\n\nBreakdown in Hex");

printf("\nfloat in hex %x ", f.floatNum);

printf("\ndouble in hex %x ", f.doubleNum);

printf("\nlong double in hex %Lx ", f.longDoubleNum);

return 0;

}
