The process of opening a file involves associating a file on disk with an object in memory: we can manipulate the file by manipulating this object, read from the file . When done with the file, it needs to be closed. Closing the file causes any outstanding operations and other bookkeeping for the file to be completed: in some cases, not properly closing a file could result in data loss.
