What is synchronization in concurrent programming?

Thread or process synchronization Thread synchronization is defined as a mechanism which ensures that two or more concurrent processes or threads do not simultaneously execute some particular program segment known as critical section.

What are fine-grained and coarse-grained locks?

Coarse-grained locking has low overhead but low concurrency. Fine-grained locking has high concurrency but high overhead. This gives a moderate degree of concurrency with a moderate amount of locking overhead.

What are coarse-grained locks?

A Coarse-Grained Lock is a single lock that covers many objects. It not only simplifies the locking action itself but also frees you from having to load all the members of a group in order to lock them.

What is the use of synchronization in concurrency?

synchronized — keyword to control the code execution by a single thread when various threads have to execute the same piece of functionality in a concurrent mode. This keyword can be applied for methods and for code blocks to achieve thread-safety.

What are the types of synchronization?

There are two types of synchronization: data synchronization and process synchronization: Process Synchronization: The simultaneous execution of multiple threads or processes to reach a handshake such that they commit a certain sequence of actions. Lock, mutex, and semaphores are examples of process synchronization.

What is coarse grained object?

Coarse-grained materials or systems have fewer, larger discrete components than fine-grained materials or systems. A coarse-grained description of a system regards large subcomponents. A fine-grained description regards smaller components of which the larger ones are composed.

What is fine grained lock?

If you have one mutex protecting an entire program, then it is coarse-grained locking. If you have many mutex, say, one per integer in your program that you might want to read or write, then you have fine-grained locking.

What is selenium synchronization?

Synchronization meaning: when two or more components involved to perform any action, we expect these components to work together with the same pace. The co-ordination between these components to run paralelly is called Synchronization. Synchronization (Wait) in Selenium has a great significant value.

How synchronization is handled in multi threading explain?

Synchronization is a process of handling resource accessibility by multiple thread requests. The main purpose of synchronization is to avoid thread interference. At times when more than one thread try to access a shared resource, we need to ensure that resource will be used by only one thread at a time.
