A video card is part of the output chain but is not an output device on it's own. The monitor is usually the device that is considered an "output device".
neither, it takes graphics related inputs from programs and processes them to produce output which then your screen outputs. think of it like a second processor which helps the main CPU do stuff its not very good at.
Output!
Input
A graphics tablet is used to to accept user input to the computer so is classed as input device ...
If you do not have a graphics card, you will be unable to receive visual output from the computer.

A TV tuner card is an input card that allows computer to receive television signals (digital or analog). A video card a.k.a. graphics card is an output card that allows to generate and output images to a display. source: Wikipedia

I expect you mean "Is Card reader/writer input or output?". If this is so, it is both an input and output 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.
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.
The sound card of a computer provides an output - speaker or headphone) and usually an input too - microphone.The card itself is not an output but is an I/O device(input output device) [a bit of semantics here].
A computer without a graphics card will have no video output. Therefore you'd only be able to play games which do not require any visuals. (I'm counting CPU's with graphics cores and built in chips as a graphics card.) a game of battleship that has no graphics and only text.... assuming you have a way to input digits and a readout or Pong if you just have a oscilloscope.
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.
An AGP card is a graphics or display card, which allows your computer to display an output on a monitor. AGP stands for Accelerated Graphics Port.
