Scanner can never be an output device! You most understand that scanner, falls into input device that helps to take input from the user into the computer.
Harddisk is an input as well as an Output Device.
If they are for hearing then its output device as they are not putting anything in to the computer, if they have a microphone attached as well then they are input/output (i.e. microphone is input, speakers are output)
well the keyboard is an input device the answers you receive after typing are the output
It's an input device, but you could argue that the LCD screen (on many cameras) is an output device. Yes. Digital Camera is an input and output device because its has a processor as well as a n LCD disply to show off output images or videos I belive it is an input device
Well, it's neither, and both. It's classified as an input/output device. Or I/O.
Touchscreen. You see them every day on kiosks, cell phones, and PDA devices. The output is what you can see on the screen. The input is when you can control the device by touching images on the screen.
A CD-ROM (using a player) is an input device because it holds information that is readable. There are writable and re-writable CD's which allow you to add or remove information making it an output device (storage device) as well.
The standard input and output devices would be sufficient for most purposes. Nowadays, when you purchase a typical computer it already includes a keyboard (input), a mouse (input), a monitor (output), and speakers (output), so you probably don't need to purchase those separately. (If you write a lot, but ONLY if you do ten-finger typing, I would strongly recommend an ergonomic (curved) keyboard, for instance one of the Microsoft Natural keyboards.) If you don't already have a printer (that's also output), you may want to purchase one as well. You may or may not need a scanner (input); one option is a combined printer/scanner/photocopier.
well a monitor is output........ dnt know what tft is..... sorry
Its more of an bidirectional device......it shows u the output graphic data as well as helps u select ur option.........
Technically speaking it is both. It can read as well write information.
Bluetooth is neither an input nor an output device. It is a wireless technology that allows devices to communicate and transfer data over short distances. Bluetooth can be used to connect input devices like keyboards and mice to a computer, as well as output devices like headphones and speakers.
