Answer:
computer users interact with their programs and applications through external devices called hardware, which allow the user to issue commands to computer programs, while also allowing these programs to issue responses to those commands. Thus, for example, the user interacts with the computer through the keyboard, by means of which he sends commands to certain programs that in turn respond, for example, through the monitor or the speakers.
According to your question you are not wrong. It in fact is correct. TRUE
Answer:
Wavelength Mismatch
Explanation:
Optical fiber cables are used because they have lowest attenuation(loss of signal strength).
Attenuation is directly proportional to wavelength.
According to me this issue is most likely caused by Wavelength mismatch.If the wavelength of the signal is high then there is more attenuation in that signal.
