Depends on the computer.
Input devices are something that gives the computer information.
e.g.

∙ 9y agoThere probably cannot be fully answered, but here are a number of the common ones, categorized by their most common roles. Some output devices can send data to the PC as well, but mostly as status data or to help the device perform its primary role (like video cards writing to system RAM). Likewise, some input devices can be written to for firmware upgrades, but that is not their primary use.
Input:
- Camera (personal)
- Digital voice recorder
- Flight controller (for flight simulation games)
- Joystick
- Keyboard
- Medical equipment (the PC can download and store their data)
- Microphone
- Mouse
- Scanner
- Security camera
- Standard CD ROM or DVD player (or burners when using only readable media)
- System BIOS (You can write to some to upgrade them on rare occasion)
- Touch pad
- Trackball
- Webcam
Output:
- Monitor
- Plotter
- Printer
- Speakers
I/O:
- CD/DVD burners
- Copying machines
- CPUs
- Fax (could be part of a modem or a multifunction printer/scanner)
- Floppy drives
- Hard drives
- Memory cards/sticks
- Musical Instruments (if you can play back through them or program from the computer)
- RAM
- Sound card (they play sound and record)
- Telephone adapter (like Magic Jack and Skype)
- USB storage devices

3 categories of peripherals?
There are many types of peripheral devices, but an example of three would be a printer, scanner,and web cam.
Is a photocopy machine an output device?
A printer marketed by the Xerox Corporation is an output device if it is connected to a computer.
Is a keyboard a input or a output devise?
Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.
Are expansion cards an input or output device?
Input I would have thought.If you are refering to the big readers of the 80-column punched card then they are Input devices. But many of these devices were made so that they could also be used for output - ie for punching cards - these are both Input and Output devices.A card reader is an INPUT (not imput) device.Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.If the computer is transmitting data to it, it is an Output device.If the computer is receiving data from it, it is an Input device.
Disadvantages of input devices?
Input Devices provide input signals to Computing devices. There can be disadvantages for a particular type of Input Device such as Mouse, Keyboard, Pointers etc. Nonetheless without Input devices Computer might not be able to receive information & remain useless.
Is a computer a input or a output?
Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.
Is graphics tablets input or output?
it's an input as well as output device.There are so many devices which behave both as input and output depending upon operation being done.
Which device can be consider as a input and out put device?
In relation to computers, there are many devices that can be considered input/output devices: Input: Mouse Keyboard Graphics Tablet Microphone Scanner Output: Monitor Speaker Printer Also, a touchscreen monitor can be considered both an input and output device.
How many input output devices can the 8085 microprocessor access?
(00-FF) 256 devices!
What are Input or Output devices?
input devices we the keyboard, the mouse, the scanner, the light pen and many other, then output devices we the following the printer, the projector, the white boards, the speakers

What is meant by console input and output in C language?
A console is simply another term for a computer terminal. All computer terminals have input and output devices but as console programmers we don't always have the luxury of knowing the specific details about those devices. All we can say for sure about any input or output device is that those devices are character streams. That is, we can extract characters from an input device and we can insert characters into an output device. Most console programs accept input via a keyboard and present output upon a screen or monitor, however it is never safe to assume that that will always be the case. This is because console programs have two global devices known as standard input and standard output (stdin and stdout, respectively). If we make use of either of these devices then we can never really be certain what physical devices are attached to them because the user must always be free to decide that for themselves. However, because all console input and output devices are character streams, it really doesn't matter what physical devices are used, we can treat them all exactly the same. A lot of new programmers often make the mistake of enforcing specific devices upon the standard input and output streams, but this is one of those cases where just because we can do something it doesn't mean that we should. Standard input/output devices must always be user-defined, never programmer-enforced. A console program can make use of as many input and output devices as it needs in addition to the standard input and output devices. Thus if a program needs to extract information from a specific disk file then it is free to do so -- there is no need to redirect standard input to that file.
What is the rule when the input is 1 and the output is 5 and input is 5 and output is 1 and input is 9 and output is -3?
There are many possible answers. One of them is Output = 6 - Input.
How many input and output in half adder?
2 input and 1 output
What is a port that can be used by many different input output devices such as keyboards printers scanners and digital cameras called?
A USB port
