Explanation / Answer

let see small examp[le :

main() { if(fork()==0 ){ } else { } }

here fork()fun. use to create duplicate process . fork fun. on success it returns 0

this process is called "child process other hand process is called "parent" process(returns >0)

so by using fork() ,we can create new process,

now "orphan process":

name it self gives meaning of it i.e if the process of child is terminated before parent process

"zombie process":convers of orphan process i.e parent process is terminated before child process is called "zombie process".

to avoid this wait() fun. and waitpid() fun. one more is there i.e sigaction all r d to avoid thiss orphan and zombie process.
