Question

A portable computer connected to a printer with an infrared interface works fine inside your office. However, when you go outside it works sporadically. How can you fix this? (select two)

a. Move the printer closer to the computer.
b. Block any direct and reflected sunlight from the pathway between the PC and printer.
c. Set the environment setting to outdoor mode in the BIOS.
d. Install a Gamma Ray Spectrometer (GRS) to shield the interface.

Answer 1

To fix the sporadic infrared connection between the portable computer and printer outside, move the printer closer to the computer and block direct and reflected sunlight that may disrupt the signal.

Step-by-step explanation:

To address the issue with the portable computer's sporadic infrared connection to the printer when used outside, there are a couple of steps that can be taken. First, we should move the printer closer to the computer to ensure a stronger infrared signal. It is essential to minimize the distance between devices when dealing with infrared communication because it is highly directional and can be obstructed easily. Second, because infrared communication can be disrupted by strong sunlight, it is advisable to block any direct and reflected sunlight from the pathway between the computer and the printer. Sunlight can introduce noise and degrade the signal strength, so by providing shade or moving to a less brightly lit location, the infrared connection should become more reliable. These practical solutions should alleviate the connectivity issues faced by the device outdoors.
