Description: Memory-Mapped I/O is a design pattern that allows programs to access files or hardware devices as if they were part of the system memory. This approach simplifies interaction with external resources, as data can be read and written directly in memory, eliminating the need for more complex input/output operations. Memory-mapped I/O is based on the idea that the operating system can assign a range of memory addresses to a file or device, thus facilitating its manipulation. This pattern is especially useful in applications that require fast and efficient access to large volumes of data, such as databases or graphics systems. Additionally, it allows multiple processes to share the same memory space, which can improve performance and resource utilization. The implementation of memory-mapped I/O can vary depending on the operating system and programming language, but its essence lies in the ability to treat external resources as an integral part of the program’s memory, simplifying development and enhancing data access speed.
