Description: Memory protection is a fundamental mechanism in computer architecture that prevents a program from accessing memory that has not been allocated to it. This system is crucial for ensuring the stability and security of the operating system and the applications running on it. Memory protection is implemented using control registers that define the memory areas accessible to each process. When a program attempts to access a memory address outside its allowed range, an exception is generated, preventing the program from interfering with other processes or the operating system itself. In modern computer architectures, memory protection is achieved through features such as the Memory Management Unit (MMU), which allows for the translation of virtual addresses to physical ones and the management of access permissions. This not only protects data integrity but also enables the implementation of advanced features such as multitasking and virtualization. Therefore, memory protection is an essential component for the safe and efficient operation of modern systems, allowing multiple applications to run simultaneously without the risk of data corruption or system failures.
