Answer:

a. modern disks do not disclose the physical location of logical blocks.

Explanation:

In modern disks, the disk scheduling algorithms are built in the disk drive. It is difficult for operating system to schedule for improved rotational latency. All scheduling algorithms are forced to behave the same because operating system may have constraints. Disks are usually accessed in physical blocks. Modern disks put more electronic controls on the disk.

Assume you have an integer pointer variable named intpoint2. It contains the address 1e6f24. You execute intpoint2++. What does
Serjik [45]

Answer:

c)1e6f28

Explanation:

The integer pointer intpoint2 points to the address 1e6f24.On increasing the inpoint.The intpoint will point to next location and since we know that the memory taken by integers is 4bytes.So the pointer will move to the next location 4 bytes ahead.

1e6f24+4=1e6f28.

Hence the answer is option c.

Which of the following statements comparing debit cards to credit cards is TRUE?
liq [111]
<span>The question has a few multiple choices one can choose from;

</span><span>A. Debit cards allow you to draw funds directly from your checking account. 
B. Debit cards typically offer greater fraud protection than credit cards.
C. Debit cards never require a signature to finalize a purchase like credit cards.
D. Debit cards charge higher interest rates on purchases than credit cards</span><span>

The Answer is (A) Debit cards allow you to draw funds directly from your checking account.

Checks were replaced by Debit cards as a way of paying for goods or drawing funds from your checking account. Since your debit card comes with your checking account, its simplicity will work nearly everywhere a credit card works. Adding a credit card to your checking account is just adding a layer of complications to your finances.
The fact that a debit card draws on money you already have, those who spend a lot would do well with debit cards and avoid the temptation of credit.</span>

Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to
jek_recluse [69]

Answer:

The solution code is written in C language.

  1.    srand(seedVal);
  2.    printf(" %d \n", rand() % 9);
  3.    printf(" %d \n", rand() % 9);

Explanation:

srand() is a C library function which seeds the random number generator. The srand() function will take one unsigned integer, <em>seedVal</em>, as input parameter (Line 1).

We can print random integer between (and including) 0 and 9 by calculating the random number modulus by 9 (Line 2-3). This will ensure the final random number will also be between 0 and 9.
