ADD COMMENT EDIT

I think this is a question of the Operating System as it is present in the operating system syllabus. So please add this question there.

IO BUFFERING

  • A user process reads block of data from a tape,one at a time, with each block having a length of 100 bytes.
  • Data should be read into user space area.
  • One simplest way would be to execute an input/output command to the tape unit and then wait for the data to become available.

There are two problems with this approach:

  • The program is hang up waiting for the relatively slow input/output to complete.
  • This approaches to input/output integers with swapping decimals by 0s.
