Os Process Management Questions
A thread is a unit of execution within a process. It represents a single sequence of instructions that can be scheduled and executed independently by the operating system. Threads share the same memory space and resources of the process they belong to, allowing them to communicate and share data more efficiently.
On the other hand, a process is an instance of a program that is being executed. It is an independent entity with its own memory space, resources, and execution context. Processes are isolated from each other and communicate through inter-process communication mechanisms.
The main difference between a thread and a process is that threads are lightweight and share resources, while processes are heavyweight and have their own resources. Multiple threads can exist within a single process, allowing for concurrent execution and improved performance. However, each process has its own memory space and resources, providing better isolation and protection.
