Thread in an Operating System
The thread refers to one string that offers the functionality of cutting a program into multiple jobs performing concurrently parallelly. A thread refers to the smallest unit of computation and comprises a program counter, a register set, and a stack space.
Within a process, a single sequence stream. It is part of a process that executes independently of other processes. Light-weight process. This is used in achieving parallelism by dividing a process’s tasks that are independent paths of execution.
For instance, multiple tabs, a browser, text editor (Spell checking, and formatting of text occur simultaneously with the type and saving of the text by various threads).

Threading Issues
Multitasking is one of the key methods, which can be applied to improve the performance of operations. In a multithreading environment, there are many threading-related problems. We shall discuss in this article threading problems associated with system calls, cancellation of threads, signal handling, thread pools, and thread-specific data.
In addition to threading problems, we shall discuss ways in which they can be handled for continued use of benefits associated with a multithreaded programming environment.
