9. What is a Computer?
Receives data (INPUT), processes data, stores data, produces a result (OUTPUT)
Computer includes:
Hardware
Software
Peripherals
In this lesson, you will begin to broaden your vision of the word computer to include many things that process and store information, including people. In fact, the word computer, in older dictionaries, is defined as a person who makes calculations.
Bottom Picture: Identify HARDWARE, SOFTWARE, INPUT, OUTPUT

10. Information Processing Cycle
Scan an item (Receives data INPUT), processes data (INTERNALLY), outputs information (ON MONITOR/RECEIPT), stores data (HD)

11. Where Are Computers Used?
