The specific explanation is as follows:

1. The first number (7) represents the permissions of the file owner. The number 7 is 111 in binary representation and represents read (4), write (2), and execute (1) permissions. Therefore, the file owner has read, write, and execute permissions on the file.

2. The second number (5) represents the permissions of the group to which the file belongs. The number 5 is 101 in binary representation and indicates read and execute permissions, but no write permissions.

3. The third number (5) represents the permissions of other users, that is, users who are not the file owner and do not belong to the group to which the file belongs. The number 5 is 101 in binary representation and indicates read and execute permissions, but no write permissions.

To sum up, 755 permission means that the file owner has read, write and execute permissions, and the group to which the file belongs and other users have read and execute permissions, but no write permissions.
