Electromagnetic interference and noise from the transmitting or receiving device.
Explanation:
Communication involves four processes, they are; encoding, sending, decoding, and feedback. A message, during this process of communication, can be altered, this is known as noise.
Telecommunication is simply communication between long distances. The effect of noise is more pronounced and can be noticed by listeners. These noises are produced by the transmitter and electromagnetic signals or waves of other transmitting devices.
The closest line to that would be the first line:
#!/bin/bash
echo "Hello World!"
BTW, the "#!" is referred to as a she-bang. When those are the first characters executed, the (requires an absolute path) program that follows is launched, and the rest of this file is given to it as data. To run this like a program, the execute permissions need to be set ( chmod 0755 script.sh ).
