The correct answer is: Scanner
The scanner is a piece of technology which unlike the printer is an input device which basically scans the top-view of any flat surface (usually paper but is definitely not limited to it) introduced in its effective range using light. The data scanned is then transfered to the Central Processing Unit for futher processing. The processed image can then be outputted and seen on the monitor's display. Once available for printing, the Central Processing Unit will just send the processed image into the printer ad voila, your scanned image is now printed in a piece of paper!
Today, scanners come with printers as a bundle. It is a perfect combination since the printer will just print the image anyway.

Answer: They are forms of of carrying data from communication devices. The difference is the medium where the signal travels.
Explanation:
Hi, the difference between guided and unguided media is that in the guided media, the signal travels through a physical medium whereas, in unguided media, the signal travels through the air.
Guided and unguided media are types of transmission media.
The transmission media carries electromagnetic signals, that transmit data between communicating devices like computers.
