What is the difference between thread and process

It is known as the active entity. A typical process remains in the below form in memory. When we start executing the program, the processor begins to process it. It takes the following steps:. A thread is the subset of a process and is also known as the lightweight process. A process can have more than one thread, and these threads are managed independently by the scheduler. All the threads within one process are interrelated to each other. Threads have some common information, such as data segment, code segment, files, etc.

But contains its own registers, stack, and counter. As we have discussed that a thread is a subprocess or an execution unit within a process. A process can contain a single thread to multiple threads. A thread works as follows:. As the name suggests, the user-level threads are only managed by users, and the kernel does not have its information.

The kernel-level threads are handled by the Operating system and managed by its kernel. These threads are slower than user-level threads because context information is managed by the kernel. To create and implement a kernel-level thread, we need to make a system call. JavaTpoint offers too many high quality services.

The diagram above shows the single-threaded process and the multi-threaded process. A single-threaded process is a process with a single thread. A multi-threaded process is a process with multiple threads. As the diagram clearly shows that the multiple threads in it have its own registers, stack, and counter but they share the code and data segment.

We will learn more about multi-threading and its models in the next blog. Hope you enjoyed this blog. Do share this blog with your friends to spread the knowledge. Visit our YouTube channel for more content.
