If any file possess all the read,write and execute
permissions means, its said to have permission set "777".
umask is a command which displays or sets the file mode
creation mask.
Means, any created file is masked with the permission set
given by umask command.
For instance, if the umask is "033" the default file
permissions will be 777-033 i.e., "744" just as file
permissions in above Balaji's answer.
