Because there are only a limited amount of ways that we need to get information from a computer but a wide variety of ways are needed to get data into a computer because of the amount of things they are used for. Output is generally in the form of visuals, print, sounds and things like robotic movement. That covers the majority of our needs. For input there are many ways we want to get information in, and new ones are being invented all the time, so there are many more of them.

∙ 14y agoI'm not sure what you mean. As far as I am aware, there exists an input for every output, and vise versa.
Speakers <-> Microphone
Monitor <-> Scanner
Printer <-> Digitizer
Text <-> Keyboard
Storage <-> External storage (CDs, DVDs, BDs, SDs, CFs, FDs, etc.)

Why the input output devices are slower than cpu or memory devices?
because of their design
What are the advantage and disadvantage of input and output device?
As there is no alternative to input and output devices, other than doing nothing, they have no inherent disadvantages.
What are the advantages of a computer input system?
with the help of input devices we get output. Steps: instruction given(data in)-->process(in processing data in cpu)--> output derived the output can only be derived when input proccessor is supported by input devices or drivers.
Can a function have more than one output per one input?
No. A function has only one output per input.
Is work output more than work input?
Work output can never be more than work input. That's a law of nature. In the real world, it's always less.
In a function can an input have more than one outputs?
No. If an input in a function had more than one output, that would be a mapping, but not a function.
What are the fundamentals of a computer?
The four fundamental parts of the computer are Processor, Memory, Input devices, and Output devices. Typically, they are tied together by something called a Bus (there may be more than one of any of the preceding).
Why is output dc higher than input ac?
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
What output is 4 more than twice the input 3?
10
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
For every input there must be only one output for it to be a function What if there was more than one output to an input is it still then a function?
No, it is not. A function can only have one output per input. (If it has more than one, it is still maths, but it cannot be called a "function". It would probably be called an equation or a formula etc...).
Is it possible to get more than one output number for each input and how?
it is possible
