What is Multithreading in OS?

Threading refers to a way in which an application traverses whenever running. Multi-Threading makes it possible for any program or operating system process to conduct two or more threads running concurrently. For each user who calls up for a specific program or system service, the program assumes a distinct identification in the form of a thread.

It is also referred to Lightweight Process, a method used in enhancing app speed. It enhances any operation system by minimizing bloated-up threads on its performance. Each thread is associated with a process and there are no threads that do not have processes.

These are also employed for running network servers as well as Web servers. In the multiprocessors this shared memory serves as a good base for execution of any program in a parallel way. Threading is being used extensively nowadays even when transacting and surfing the internet.

The threading section threads codes in very small light pieces so that the CPU loads are distributed equally to allow quick completion of any function. Every thread has its own separate resources by means of which we can perform any process on its own, or increase the amount of threads to make multiple processes work in parallel.

What is Race Condition?

Race condition refers to an OS problem where two or more processes or threads execute concurrently. Their order of execution determines whether they will be killed. In case of race, the precise moments at which events occur cannot be specified, and the product of execution can change according to time. This can lead to some undesirable or erroneous operation of such a system.

What is Process Synchronization?

This ensures that such a synchronization between the installed operating system is aligned with the processor present on the computer system. This implies that, if the next stage of processing requires printing; then the processor will send a command to the operating system and subsequently waits for a response that either prints or fails to print.

The operating system detects it as soon as it is printed and the reply is communicated to the processor which implies that synchronization of these parties are required.

What is Mutex (Mutual Exclusion)?

The term “mutual exclusion” (or MUTEX), which stems from the property of “critical section” refers to a situation where two threads/processes wish to access shared resources simultaneously. However, this issue comes up when a shared resource is unsecured and two or more threads or processes try to use it at once resulting in race conditions, data inconsistencies, and so on.

What is Deadlock?

Two computer processes have access to single resource and neither process can access to this resource. so, deadlock occurs. Here we mean by saying deadlock, a situation wherein two processes crave for the same resource and each of them cannot get access to that very resource leading to deadlock in the existing system.

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.
