When a parent process creates a child process, this child process is given resources such as CPU time, memory, files, I/O devices, etc. in order to complete its task, these resources come from either its parent or directly from the OS. What are some cases where the child process might have to draw resources directly from the OS instead of its parent? Can you show some examples of a parent process and its subsequent child process(es) from an user application like a web browser, text editor or any other user application? In a parent-child relationship, both process are able to communicate and might go their separate ways if the child process has a new program loaded into its memory, can you provide an example of a parent and child process going separate ways in a system or user application?
