Unix Interviewfragen und Antworten
Question: 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:the process dispatcher, vhand and 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). |
