Shared memory

Shared memory is a method used in computing where multiple processes (or programs) can access the same block of memory simultaneously. This allows them to communicate and exchange data quickly without needing to copy information back and forth, which can be slower. Imagine it like a shared whiteboard where several people can write and read notes at the same time. It's efficient for tasks that require fast collaboration, like video games or real-time data processing, but it also requires careful management to avoid conflicts and ensure that everyone sees the correct information.
