The default file permission is 666 and directory perm. is 777, and umask

Sorry to all Technical person for mistake of Question.
Now i am post currect question
Why copied file permission is changed in destination. When i
give all permission i.e 777 to file and copy that to other
location in destination the permission is 755. But if give
permission 555 in destination that file permission is 555
and if give permission 444 to file after copy in destination
the file permission is 444. These all are happening in
normal user. How the umask value is calculate here really i
am not understand. Please write the proper answer. Thanks
in Advance

The default file permission is 666 and directory perm. is
777, and umask default perm. is 022.
If you copied a file which is having 777 permission to
another location. umask will apply while copy the file.
hence 777 -(minus) 0222= 755 which is the default
permission of a file.
