What are the functions of a computer?

The four basic functions of a computer are: input, storage, processing, and output. The computer operates according to instructions stored in its own memory unit and can accept inputted data, process that data arithmetically; and through sequence-based logic, it can produce information and store the results for future use. All the applications of a computer derive from one of these four functions.

While the functions and applications of a computer are almost endless, we can sense four primary purposes that are all linked to data (information):  Entering data, manipulating data, viewing processed data, and storing data.  Computers are designed to transform raw data into information.  The computer operates under the control of instructions stored in its own memory unit and can accept inputted data, process it aritmethically and through sequenced based logic, produce information, and store the results for future use.  All the applications of a computer derive from this basic starting point.
