Uniform Memory Access (UMA) is a computer architecture design where all processors in a system share a single, uniform memory space. In this setup, each processor can access any memory location with the same speed, ensuring consistent performance across the system. This design simplifies programming and resource management, as developers do not need to consider varying access times. In UMA systems, the memory is typically organized in a way that allows multiple processors to read and write data simultaneously. This architecture is commonly found in multiprocessor systems, where efficient communication and data sharing are crucial for performance.
