SUBMITTED TO: - LOVELY SCHOOL OF COMPUTER SCIENCE

INTRODUCTIONA diary is a record set (originally in handwritten format) with some type entries arranged with date, what has happened over the day or other period. A personal diary may include a person's experiences, which is hiding from others and thoughts or feelings, including comment on current events outside the writer's direct experience. Diaries undertaken for institutional purposes play a role in many aspects of human civilization, including government records. The term diary is some time called personal diaries, normally intended to remain private or to have a limited circulation amongst friends or relative. The word journal may be sometimes used for diary but generally diaries have daily entries, whereas journal-writing can be less frequent.
