For an external usb hard drive attached to a computer, which is more suitable: a writethrough cache or a block cache
Charra [1.4K]

Disk access is way slower than memory access. Caching is a technique to improve the disk access time.  Block cache is a caching technique which reduces disk accesses time.  Here a portion of disk is bought to cache for reading and a modified blocks are first changed in cache but reflected in the disk at one go.  On the other hand with write through caching each modified block is written to cache and at the same time it is written to the disk.  Write- through caching requires more disk I/O so they can have a negative effect on the performance.

           result = scan.nextInt();

           if(result==n1*n2){

               System.out.println("Correct. Nice work!");

               correct++;

           }

           else{

               System.out.println("Incorrect. The product is "+(n1*n2));

           }

Which type of element is , and what is the meaning of that element?
IrinaK [193]

Answer:

1. Semantic

2. modifies

Explanation:

Semantic HTML is understood by the traditional browser, and semantic tags are the one that ensures not just presentation, but also adds the meaning to the webpage. And hence, img here is both semantic as well as presentational. Hence, the first option is semantic. And the IMG modifies the meaning of the web page. The description is done by the text. And hence the second option is modified.

What is the effect of this program?
Mrac [35]

Answer:

The answer is (C)

Let’s run the algorithm on a small input to see the working process.

Let say we have an array {3, 4, 1, 5, 2, 7, 6}. MAX = 7

  • Now for i=0,  i < 7/2, here we exchange the value at ith index with value at (MAX-i-1)th index.
  • So the array becomes {6, 4, 1,  5, 2, 7, 3}. //value at 0th index =3 and value at (7-0-1)th index is 6.
  • Then for i=1, i < 7/2, the value at index 1 and (7-1-1)=5 are swapped.
  • So the array becomes {6, 7, 1,  5, 2, 4, 3}.
  • Then for i=2, i < 7/2, the value at index 2 and (7-2-1)=4 are swapped.
  • So the array becomes {6, 7, 2,  5, 1, 4, 3}.
  • Then for i=3, i not < 7/2, so stop here.
  • Now the current array is {6, 7, 2,  5, 1, 4, 3} and the previous array was{3, 4, 1, 5, 2, 7, 6}.

Explanation:

So from the above execution, we got that the program reverses the numbers stored in the array.
