8. I/O and BIOS I/O stands for Input/Output BIOS stands for Basic Input/Output System

9. In computing, input/output, or I/O, refers to the communication between an a computer, and the outside world. Inputs are the signals or data sent to the system. Outputs are the signals or data sent by the system to the outside.

10. The first unit we cover is the one you use every time you do something on the computer… THE UNIT

11. The INPUT UNIT of the computer accepts information. It allows a user to put information into the computer by using input devices.

12. An input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system (such as a computer).

13. USER The person who uses the computer or the programs and software.

14. Those pieces of input and output equipment are called PERIPHERALS.

15. Equipment that is not part of the central computer but are attached to and work with the central computer.

16. Input and output devices make up the hardware interface between a computer and the user or outside world.

17. Just one “heads up”, word of caution or word of warning to you about INPUT and OUTPUT devices. Some devices are INPUT ONLY Some devices are OUTPUT ONLY Just one “heads up”, word of caution or word of warning to you about INPUT and OUTPUT devices. Some devices are INPUT ONLY Some devices are OUTPUT ONLY But There are some devices that can act like or be used as both INPUT and OUTPUT But There are some devices that can act like or be used as both INPUT and OUTPUT

18. DEVICES OR EQUIPMENT THAT CAN ONLY BE USED TO INPUT INFORMATION

19. DEVICE A mechanical invention or contrivance for some specific purpose.

20. A human interface devices is a type of computer device that interacts directly with humans, takes input from humans and allows them to communicate with computers. HUMAN INTERFACE DEVICE

23. You should remember that these are devices that are used only to put information into the computer. They are not used for output. Many of them are not used with the PC’s, laptops, notebooks or home computers most people have and use.
