Concurrency control in distributed systems ensures data consistency and integrity by managing simultaneous operations across multiple nodes. It prevents issues like race conditions and conflicts that can arise when multiple users or processes attempt to access or modify shared resources concurrently. By implementing mechanisms such as locking, timestamps, or optimistic concurrency control, systems can maintain a stable state and ensure that transactions are executed reliably, ultimately enhancing system performance and user experience.

What is distributed system?
A distributed system is collection of indendent computers that appears to its users as a single coherent system. BY arvind yadav 0612613015 INDIA.
How does dma increase system concurrency?
Direct Memory Access (DMA) increases system concurrency by allowing peripheral devices to transfer data to and from memory independently of the CPU. This offloads the data transfer workload from the CPU, enabling it to perform other tasks simultaneously instead of waiting for I/O operations to complete. As a result, the overall system efficiency improves, and multiple processes can run concurrently without being bottlenecked by data transfer operations.
What are the real life examples of distributed system?
One real life example of a distributed system is a render farm, which is used for rendering 3D graphics in animated movies. Another would be massive multiplayer online games.
What happens when coins are made?

What Database management system is how to control concurrency?
Concurrency control in a Database Management System (DBMS) is managed through techniques that ensure multiple transactions can occur simultaneously without leading to inconsistency. Common methods include locking mechanisms, where resources are locked for exclusive access, and optimistic concurrency control, which allows transactions to proceed and only checks for conflicts before committing. Additionally, isolation levels define how transaction integrity is visible to other transactions, influencing concurrency behavior. These strategies help maintain data integrity while allowing for efficient access in multi-user environments.
