Understanding Input and Output Devices

The video tutorial introduces the concept of input and output devices in computers. It uses everyday examples, like making orange juice and potato chips, to explain how input is processed to produce output. The tutorial defines input devices as tools that send instructions to a computer, such as a mouse, keyboard, joystick, and webcam. Output devices, like monitors, printers, and speakers, display the results of processed inputs. The CPU, known as the brain of the computer, processes these inputs. The lesson concludes with a recap of the devices and their roles in computing.
