Introduction to Synchronization
What is Synchronization?
Synchronization mainly occurs between the nodes of a network in order to ensure that the data streams are transmitted and received in a correct manner and the data collision is prevented. It usually includes a clock signal which transmitted in the series with a data stream in order to properly maintain the signal timing. In the context of .NET, synchronization is a process which includes the coordination of various threats for ensuring desired outcomes without any corruption of the shared data. It is helpful to prevent the occurrences of race conditions as well as deadlocks. Synchronization forms the basis of execution of various threads in the multithreaded application in an asynchronous manner (Sindhu & Sangwan, 2017). It also provides the means in order to achieve the resource sharing such as the network connection, information sharing, file handling and memory with the corporation of threads as well as processes in order to avoid the corruption of data. It is designed to be cooperative and demanding which is followed by each of the thread in the system before any access to the protected resource of information. Locking synchronization, lightweight synchronization, and signaling synchronization are the different types of synchronization. In the .NET interlocked operations and spin wait are the mechanisms of synchronization.
What are the types of synchronization?
Synchronization is used in the context of multithread applications in which there is proper control of the resources to be shared across the different threads. Otherwise, it can lead to an undesirable and unpredictable outcome. Following are the two types of synchronization:
1. Process synchronization
2. Data synchronization
Process synchronization is the simulation of the multiple processes or threads in order to reach towards the handshake such that they can commit certain sequences of actions. some of the examples of process synchronization include mutex, semaphores, and lock. On the basis of synchronization, processes are further categorized into the independent and cooperative process. In the case of cooperative processes, the problems related to the process synchronization arises. The process synchronization was introduced in order to handle the problems which arise when there is multiple process execution. The synchronization of processes means the sharing of system resources by the processes in such a way that the concurrent process of the sharing of data can easily be handled and the chances of data inconsistency can be minimized. Process synchronization occurs in an operating system among various cooperating processes (Lande & Ali, 2018). When there is the execution of the concurrent processes, the process synchronization is helpful in order to maintain the shared data consistency and also cooperating the execution of the processes. There should be proper scheduling of the processes in order to ensure that the concurrent access the shared data is not able to cause inconsistencies in the data.
Data synchronization include the maintenance of the data in order to keep multiple copies of the data which is coherent as well as to maintain the integrity of data. For example, the replication of data is used in order to keep multiple copies of the data synchronized along with the database servers which store the data in the different locations. Data synchronization is enabled through the specialized software which tracks the versions of data which is created as well as utilized. The data synchronization process is implemented in the distributed systems from where the data elements are routed between different systems or computers. Each system may modify the versions of original data on the basis of different requirements. It ensures all the changes which are merged with the different sources of data regardless of the modifications of data. data synchronization is also used in the data mirroring in which each of the data set is synchronized or replicated within another device (Chhikara, 2014).
Benefits of data synchronization
Data availability and response time are the main benefits of data synchronization. Data synchronization has data availability as the main benefit. Data is locally available rather than through expensive, less reliable as well as slow connections in the single and central databases. Even in the absence of a good connection, the data can be accessed easily from any of the central databases. There is no need to cut off the data in event of a failure in the connection of network. Along with this, data synchronization is able to improve the response time for the requests of data. retrieval rate is also faster because the requests are processed on the location server without any access to the wide area network. Also, the local processing offloads work from the central database server in order to decrease the competition for the processor time (Latha & Shashidhara, 2010).
