Well, it's neither, and both. It's classified as an input/output device. Or I/O.
It would definitely be both. Output because it sends out information, and input because it then receives information.
yes its input but somewhere i had read its both input and output ,but i cannt understand why its output . regards Hashaam zahid hashaamzahid3@gmail.com
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. 1.Modems 2.Network Cards. 3.Touch Screen. 4.Headsets. 5.Facsimile (Fax). 6.Audio Cards/Sound Card.

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 both.
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].
Input devices include mouse & Keyboard. Output devices include Graphic Display & Speakers. Input/Output devices would include a Network Interface Card.
All programs require both input and output. A program that does not require input or output has no data to process, and without data to operate upon a program is essentially useless. There can be good reasons not use certain input or output devices. For instance, a router has no need for a keyboard for input or a screen for output. However a router is network-enabled and the network interfaces are used for both input and output.
