Consider a file system that uses inodes to represent files. Disk blocks are 2KB in size and a pointer to a disk block requires 4 bytes. Consider a file whose inode has 6 direct disk blocks, plus 1 single indirect, and 1 double indirect disk blocks. What is the maximum size of the file? If we use bitmap to manage the free space, how many disk blocks are required to hold the bitmap of 32 GB disk?



a.  Maximum size of file = 8.003 GB


a. Maximum size of file

= (6 * 2 KB) + (2048 * 2 KB) + (2048 * 2048 * 2 KB)

= 12kb + 4096 Kb +  8388608 kb

= 8392716 kb

8392716/1024 mb = 8196.01 MB

8196.01 /1024 GB= 8.003 GB

b. According to above calculation

For 8 GB 6 direct, 1 single and 1 double indirect block requires


for 32 GB

24 direct Block

4 single and 4 double indirect block requires


Which of the following protects against cave-ins? A. All answer choices protect against cave-ins B. Shielding C. Shoring D. Sloping


Answer: A) All answer choices protect against cave-ins

Sloping is the method in which prevents the sloping back of elements of site while experiencing high pressure. Shielding is the form of covering that is obtained by using trench boxes or other element for the support to act as shield .

Shoring is the technique in which prevention of cave-in is done through hiring aluminum hydraulic and related supporting components so that cave-ins can be stopped. Thus, all the options are correct.

Write a program to check if an input is a valid hashtag (starts with #, contains only letters, numbers, and underscore, no space or special characters). (1) Name your program hashtag.c.

(3) Library function isalpha(), isdigit(), and isalnum() are not allowed in this program.
(4) Use getchar() to read in the input.



C code is given below



int main()



  int ch;

  int valid=1; // it is set as 1 initially if anything is wrong it is changed to 0


  if(ch!='#') // it checks if it starts with #




while((ch = getchar())!= '\n') // this loop runs till line ends




When you use file explorer or windows explorer to delete a file from the hard drive, where does windows put the file?


Trash bin


When you remove a file from the hard drive it is still written in binary code. So, windows places files in the *trash bin* if you did not want to delete it.
Unless USB or Removable flash drive, when you delete that it does not place any files in the trash bin.
