File access methods:

The data contents that are present in a file can be accessed by the 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 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 a temporary file is to allocate a file for temporary usage. It is used to hold data temporarily for implementation of program.
