True: LWP is ____. In the traditional meaning of the term, as used in Unix System V and Solaris, an LWP runs in user space on top of a single kernel thread and shares its address space and system resources with other LWPs within the same process. In the realm of operating systems, we have already noted that the fundamental abstraction is the notion of a process.
