Generally, the two main input devices are a keyboard and mouse, while the two main output devices are a monitor and printer.
INPUT- keyboard and mouse
OUTPUT- speakers and monitor
Head sets have speakers on two ears and a microphone. The speakers are output devices and the microphone is an input device. So if a headset is an input/output device.
A motherboard is nor an output nor an input device. It is in the middle of these two and is a processing hardware device
Input: Mouse and Keyboard Output: Monitor and printer
Neither, it is a storage device. But if you MUST choose between the two, choose output device.
I believe you are referring to the screen only. A touch screen works as a input and output device
An input device is basically any device or peice of equipment that you connect to a computer ect that sends data into the computer to be processed. Examples can include anything from keyboards or mice to temperature and pH probes to digital cameras. Note that devices such as printers and moniters are OUTPUT devices, ie they display information.
If you mean "does a touch screen count as an output device", then the answer is "yes, in part". A touch screen is actually two components -- a touch-sensitive surface of some type over the top of a grid of pixels.The touch-sensitive surface is an input device, but the actual display components are an output device. Therefore, the touch sensitive display as a whole is both an input device and an output device.
The CPU and Memory. But generally you also need an Input device and an Output device.
Devices for communication between computers, such as modems and network cards, typically serve for both input and output. Also, a touch screen can be considered as an input and output device. Others include: Fax, 3-in-1 printers, headsets, and audio/video cards.
There are two input and output ports for Input 1 and 2 and Output 1 and 2.
input ;keyboard ,mouse output: monitor , speaker , printer
1. Input device 2. Unit Processor - consists two parts: central processing unit (CPU) and main memory - CPU is divided into two main parts: a control unit and arithmetic/logic unit + registers 3. Auxiliary storage device 4. Output device Cheers, Rajz
