Students in a class in New Delhi have been communicating with a class in Chandigarh by videoconference. The two classes find that the images they receive from each other occasionally freeze for up to 30 seconds before the video continues. This type of problem can most often be solved by
AIncreasing bandwidth ✓ Correct
BUpgrading cameras
CIncreasing video resolution
DUpgrading monitors
Correct answer: (A) Increasing bandwidth — The answer is by increasing bandwidth.
Explanation
★The answer is by increasing bandwidth.
★Freezing video during a videoconference is usually caused by too little data throughput.
★Bandwidth is like the width of the pipe carrying the data.
★More bandwidth lets more video data flow smoothly, so the freezing stops.
★So this problem is most often solved by increasing bandwidth.
★Better cameras, resolution or monitors would not fix the freezing.
★So the answer is by increasing bandwidth.
