Symmetric Multiprocessing (SMP) is a computer architecture where two or more identical processors share a single, main memory and are connected to the same operating system. This setup allows multiple processors to work on different tasks simultaneously, improving performance and efficiency. Each processor can access the memory equally, which helps in balancing the workload. In an SMP system, all processors are treated equally, meaning they can execute any task assigned by the operating system. This design is commonly used in servers and high-performance computing environments, as it allows for better resource utilization and faster processing of complex applications.
