File access methods: The data contents that are present in a file can be accessed by following two ways: Sequential access Random access or direct access Sequential access file: In sequential access method, the contents of the file are accessed from the beginning to the end. The contents of the file can be read only in order; skipping the contents between files is not possible. It must read the contents from the beginning of the file, which takes more time. Temporary file: The purpose of temporary file is to allocate a file for the temporary usage. It is used to hold a data temporarily for implementation of the program.
