Shared Memory Systems are a type of computer architecture where multiple processors or threads can access a common memory space. This allows them to communicate and share data efficiently, making it easier to coordinate tasks and improve performance. In these systems, memory is typically divided into segments that can be accessed by different processes, enabling faster data exchange compared to other methods like message passing. In a shared memory environment, synchronization mechanisms, such as mutexes and semaphores, are often used to prevent conflicts when multiple processes attempt to read or write to the same memory location. This ensures data integrity and consistency, which are crucial for the correct functioning of applications that rely on shared resources.
