Threads in Operating Systems
A thread is a path of execution that is composed of a program counter, thread id, stack and set of registers within the process. In general, a thread is a least unit of the process that represents an independent sequence of execution within that process. It is a basic unit of CPU utilization that makes communication more effective and efficient, enables the utilization of multiprocessor architectures to a great scale and greater efficiency, and reduces the time required in context switching. With the support of multiprocessor architecture, the communication between the multiple thread is easier as they share memory resources. Sometimes thread also called a lightweight processes because they have their own stack but can access shared resources.
Thread Libraries
The Operating System is an interface between the user and hardware that enables the interaction of computer hardware and software or it can act as a bridge between the user and the application. It ensures that various software programs can run efficiently and interact with hardware as needed. Some Popular Operating Systems are Linux, Unix, Microsoft Windows, and so on. Without an operating system computer is useless.
