Buffered file input is basically the operation where data previously cached in the buffer is read from the buffer and written into a file. This type of operating procedure is often used to reduce database or file input/output so that overall performance is enhanced. This type of procedure is used most commonly in C and UNIX where these languages supply standard packages for performing buffered file input and output.
Since there are no input/output statements in C there is a specific operating approach to input/output that makes C's file system very flexible and powerful. This approach uses the buffer, an area of memory used for storing information, and all input/output file operations occur via calls to functions in the standard operating library.
