What is the difference between a process task and threads?

Answer:

process and task as synonymous. One or more threads
together form a process. The threads, two or more belong to
same process, share same address space of the process and
can access all the global variable of the process.

space and hence cant access their global variable. Two
processes can talk with each other using IPC.

process from the parent process?
