Difference among a process task and threads

Question

What is the difference among a process task and threads and what are the things which are obtained by the child process from the parent procedure?

Answer 1

Process and task is as synonymous. One or more threads together make a process. The threads, two or more associate to same process, share similar address space of the procedure & can access the entire global variable of the procedure. While two of the processes can't access each other's address space & therefore can’t access their global variable. Two processes can talk with each other via IPC.
