Study Notes
- Computer: An electronic device that accepts data from a user, performs operations and calculations, and produces output as a result
Function of Computers
-
The flow is Input -> Processing -> Output -> Storage memory
-
Input: Data and information entered into a computer is called input
-
Processing: Sequence of actions on data to convert it into meaningful information for the user
-
Output: Output screen for data
-
Storage: Permanent storage of data
-
Data processing consists of Input, Output, and Processing
