Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
Answer:
method for user authentication to the network
Provide detailed information about a user
Explanation:
An in AD, a user account consists of all the information that includes user names, passwords, and groups. All these information defines a domain user in which a user account has membership access to. With the advanced features of Kerbos, mutual authentication in user accounts to a service is achieved.
Answer:
I. hatching
II. filter
Explanation:
Sarah is creating an image. She wants to achieve tonal effects with parallel lines by varying their densities and distribution patterns. She will use <u>hatching</u> to do this. She also wants to add special effects on the image. Therefore, she will use <u>filters</u>.
Hatching refers to an art technique in which parallel lines are used to shade by drawing them closely together.
Stippling is an art technique used in the making of patterns by using small dots.
Filters is a technique of changing image characteristics. It is used to change the picture characteristics & to add special effects to an image such as the shade, contrast, tone, brightness etc.
We therefore see that, <u>hatching</u> and <u>filter</u> are the correct answers respectively
Answer:
import java.util.Arrays;
public class swap{
public static void main(String []args){
int [] arr = {2,4};
swapValues(arr);
}
public static void swapValues(int[] values){
int temp;
System.out.println(Arrays.toString(values));
temp=values[0];
values[0]=values[1];
values[1] =temp;
System.out.println(Arrays.toString(values));
}
}
Explanation:
In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.
Answer:
See explaination
Explanation:
void showSeatingChart(string seatingChart[20][40], const int ROWS, const int COLS){
for(int i = 0;i<ROWS;i++){
for(int j = 0;j<COLS;j++){
cout<<seatingChart[i][j]<<" ";
}
cout<<endl;
}
}
