input output bound program is a program (or process in precise way), which spends most of time allocated to it for execution, on input/output devices and need very small CPU time for it.
Output documentation
The input means the problem and the output means the answer! [but not in math]
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.

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.
Desktop are both, mean input and output, but in some times it is call out put device.

input, output, program, action, response
Assuming by in you mean input and out you mean output. Input is the value that goes in while the output is the value you receive. Between these terms is a rule, called the nth term that will always work to help you find the input/output. For example. Our input is 2, and our output is 10 the rule here could be the input multiplied by 5 equals the output, or it can be something extremely difficult and unfathomable even to a banker...
Mozilla Firefox is a program. It receives input from the user and remote servers, and outputs that information to the screen. It can also output information to local files or remote servers.
If you mean, "what devices can act as input and output?" then the answer is Touchscreens. Multifunction scanners/printers DO NOT count.
