Description: A file buffer is a temporary storage area in memory used to hold data being transferred to or from a file. This mechanism is fundamental in memory management within computing environments, as it optimizes the performance of input and output (I/O) operations. Storing data in a buffer reduces the number of direct disk accesses, which are significantly slower compared to memory operations. Buffers can vary in size, and their management is crucial to prevent data loss and enhance system efficiency. Additionally, buffers allow applications to continue functioning while I/O operations are performed, contributing to a smoother user experience. In summary, the file buffer acts as an intermediary between memory and persistent storage, facilitating data transfer and improving overall system performance.
