INPUT and OUTPUT Devices
Input and output devices
- Any information or data that is entered or sent to the computer to be processed is considered input.
- Anything that is sent from the computer to an internal or external device is output .
Input devices
- An input device, such as a computer keyboard or mouse , can send information to the computer, but it cannot receive information from the computer.
Output devices
- An output device, such as a computer monitor or printer , can receive information from the computer, but it cannot send information to the computer.
- An input / output device, such as a CD-RW drive or USB flash drive , can send information to a computer and receive information from a computer.
Input / Output devices
CD-RW drive
USB flash drive
- Find a USB port.
- Insert a USB flash drive into the USB port.
