I request your valuable feedback on the following questions:

1)system call overhead - what happens on a system call
  and what is the overhead involved.

  If all tasks run in privileged mode/supervisor mode,
  how can we reduce system call overhead.

2)My understanding of address space :
  The text, data, and bss portions of a task

  If two tasks share a common address space which portions
  (text/data/bss) are shared.
