If two links to an existing file are created in the same directory as the original (using the link syscall), how many inodes are used to store information about the three directory entries?

The opendir() function opens a directory stream corresponding to the directory name, and returns a pointer to the directory stream. The stream is positioned at the first entry in the directory. Why does the openir() function not fetch fd as return value even though it is a system call?

The following system call adds read permission for a process (for_pid) if the caller (call_pid) owns the file, and does nothing otherwise. (The operating system supplies call_ pid; the caller supplies the two latter parameters.) function addread(call_pid, for_pid: process_id; fid: file_id): integer; begin if (call_pid = filelist[fid].owner) then addright(filelist[fid].access_control_list, for_pid, "r"); result := (call_pid - filelist[fid].owner); return result end. Is the variable result directly or indirectly visible, or not visible? Is the variable filelist[fid].owner directly or indirectly visible, or not visible? Is the variable filelist[fid].access_control directly or indirectly visible, or not visible?

What is the significance of inode pointers in Unix-like file systems, and how do they facilitate directory operations?

Why should I maintain two copies of the identical file if I can just delete one of them?

In Minix or UNIX-like operating systems, when a file system is mounted, the directory chosen for the mount point must be an empty directory. True False

On your own computer, find four files that are stored in four different directories. For each file, list both the relative file name and its complete file name.

Using any database (one we have created before or a new one), create a program that uses Scanners OR Window Builder to take input from the user and perform: • One 'SELECT' query • One 'INSERT' query • One 'UPDATE' query • One 'DELETE' query *The queries you decide to perform are completely up to you*

Refer to the previous question. How many passes will it take to sort the file completely?

Could you give me the correct word for a collection of files that go together?
