Is it possible for the two types of permanent storage to be used interchangeably? Explain your answers.

Further a flat file “provide another means of supplying input and producing output” (Venit, 2004, p. 132). There are data, text or binary files the above can be created in a specified formatted by a program. Flat files were also used at one time to store information on PDA’s, maybe the first models made. The concept was similar to a mini-database. The flat file storage limits were low. Flat files gather information from one system then using a protocol such as file transfer send this file to another system.
