Answer 1

File system is designed to work with a wide variety of devices, including terminals, disk drives, tape drives etc. Even though each device is different, file system transforms each into a logical device called stream. Streams are device independent so same function can be used to write a disk file and a tape file. In more technical term stream provides a abstraction between programmer and actual device being used.
