Study Notes
Computer Basics
- A computer is an electronic device that processes data through three stages: input, processing, and output.
- Input involves capturing necessary data for a program using input devices.
Input Stage
- Input devices facilitate data entry; common examples include the mouse and keyboard.
- Users utilize these devices to feed information into the computer.
Processing Stage
- The processing stage involves executing instructions contained in a program using the input data.
- The output generated at the end is based on the manipulated input data.
Output Stage
- Output is the stage where processed data is transformed into useful information for the user.
- Output devices display the information; common output devices include monitors (or visual display units, VDUs) and printers.
Data vs. Information
- Data consists of numbers, characters, or symbols formatted for input into a computer, lacking intrinsic meaning.
- Processing converts raw data into meaningful information by providing context.
- Data types that can be input into a computer include numeric values, text, dates, graphics, and sound.
- All data is ultimately stored as a series of numbers within the computer.
- Users can input data through various methods tailored to the type being processed.
