Threads
Overview
A thread is a basic unit of CPU utilization; it comprises a thread ID, a program counter, a register
set, and a stack. It shares with other threads belonging to the same process its code section, data
section, and other operating-system resources, such as open files and signals. A traditional (or
heavyweight) process has a single thread of control. If a process has multiple threads of control, it
can perform more than one task at a time
