Giving out is called OUTPUT
Water is the input and flowers are the output for the plant.
Input Devices
Input devices allow us to send information to the computer.
Examples of Input Devices are: Keyboard and Mouse.
Output Devices
Output devices allow us to receive information from the computer.
Examples of Output Devices are: Monitor, Speaker and Printer.
Processing
The CPU is neither an input nor an output device. It takes the information given by
the input devices and sends the result to the output devices. This is called processing.

and held a book in his hand. He smiled and said, “Good morning, Haldi.”
Haldi looked up at him. “I’m sorry to stare,” she said, “but I have never met a giraffe like you.
” “My name is Smiley,” said the giraffe. “Whenever you see me, you will smile.”
