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.
