FAQs on Node js tutorial step by step 9 Shared memory Modules Video Lecture - The Complete NodeJS Developer Course (in Hindi) - Back-End Programming

1. What is shared memory in Node.js?
Ans. Shared memory in Node.js refers to a mechanism that allows multiple processes or threads to access the same memory region. It enables efficient communication and data sharing between different parts of an application.
2. How can shared memory be utilized in Node.js modules?
Ans. Shared memory can be utilized in Node.js modules by using modules like `node-shared-memory` or `shm-typed-array`. These modules provide APIs to create and manage shared memory regions, allowing data to be shared between different instances or threads of a Node.js application.
3. What are the advantages of using shared memory modules in Node.js?
Ans. The advantages of using shared memory modules in Node.js include improved performance due to efficient data sharing, reduced memory usage by avoiding unnecessary data duplication, and simplified communication between different parts of an application.
4. Are there any limitations or risks associated with shared memory in Node.js?
Ans. Yes, there are some limitations and risks associated with shared memory in Node.js. One of the main risks is the potential for data corruption or race conditions when multiple processes or threads access the same shared memory region concurrently. It requires careful synchronization and locking mechanisms to ensure data integrity.
5. Can shared memory be used in distributed Node.js applications?
Ans. Yes, shared memory can be used in distributed Node.js applications, but it requires additional considerations and mechanisms for synchronization across different machines or processes. Technologies like distributed shared memory systems or distributed file systems can be utilized to achieve shared memory functionality in a distributed environment.
