Brief About The Initial Process Sequence While The System Boots Up.?

Answer»

While booting, special process CALLED the 'swapper' or 'scheduler' is created with Process- ID 0. The swapper MANAGES memory allocation for processes and influences CPU allocation.

The swapper INTURN creates 3 CHILDREN:

  1. the process dispatcher,
  2. vhand and
  3. dbflush

with IDs 1,2 and 3 respectively.

This is done by executing the file "/etc/init". Process dispatcher gives birth to the shell. Unix KEEPS track of all the processes in an internal data structure called the Process Table (listing command is ps -el).
