Each part has a specific function. Before we discuss the control unit and the arithmetic/logic unit in detail, we need to consider data storage and its relationship to the central processing unit. Computers use two types of storage: Primary storage and secondary storage.
With a worldwide box-office gross of over $2.7 billion, Avatar is often proclaimed to be the highest-grossing film, but such claims usually refer to theatrical revenues only and do not take into account home video and television income, which can form a significant portion of a film's earnings.
The film was partially funded by Paramount Pictures and 20th Century Fox, its distributors. At the time, it was the most expensive film ever made, with an estimated budget of US$200 million. In 2009, James Cameron's Avatar (the first film Cameron had made since Titanic) topped Titanic, however. The film was originally scheduled to open on July 2, 1997; however, post-production delays pushed back its release to December 19 instead. Titanic was an enormous critical and commercial success.
