How does a hard drive work

Computers and Technology
1 answer:
svetlana [45]3 years ago

A small hard drive typically has only one platter, but each side of it has a magnetic coating. Bigger drives have a series of platters stacked on a central spindle, with a small gap in between them. The platters rotate at up to 10,000 revolutions per minute so the read-write heads can access any part of them.

4vir4ik [10]
A. Resize

By dragging the border of a field or record, you are either enlarging it or compressing it. Choices "b" and "d" are only half correct, as there is always the possibility of making it smaller. Hope this helps!

Blababa [14]
The answer is B) Template. 

Various templates are available in most all desktop publishing programs, from resume templates in Word to Income Statement templates in Excel. Templates are useful for skipping the general "setup" process of making a document, and allow you to focus more on filling the document with the relevant data and polishing it to your specific needs once most of the legwork is done.

Write the half function. A function call and the functionprototype
EastWind [94]

Answer:

C code for half()

#include<stdio.h>

void half(float *pv);

int main()

{

float value=5.0;  //value is initialized  

printf ("Value before half: %4.1f\n", value); // Prints 5.0

half(&value);  // the function call takes the address of the variable.

printf("Value after half: %4.1f\n", value); // Prints 2.5

}

void half(float *pv) //In function definition pointer pv will hold the address of variable passed.

{

*pv=*pv/2;  //pointer value is accessed through * operator.

}

  • This method is called call-by-reference method.
  • Here when we call a function, we pass the address of the variable instead of passing the value of the variable.
  • The address of “value” is passed from the “half” function within main(), then in called “half” function we store the address in float pointer ‘pv.’ Now inside the half(),  we can manipulate the value pointed by pointer ‘pv’. That will reflect in the main().
  • Inside half() we write *pv=*pv/2, which means the value of variable pointed by ‘pv’ will be the half of its value, so after returning from half function value of variable “value” inside main will be 2.5.

Output:

Output is given as image.
