What is packet loss? - Definition from Whatis.com

The effects of packet loss:

  • communications, such as VoIP, it can cause jitter and frequent gaps in received speech.
  • In the worst cases, packet loss can cause severe mutilation of received data, broken-up images, unintelligible speech or even the complete absence of a received signal.

The causes of packet loss include inadequate signal strength at the destination, natural or human-made interference, excessive system noise, hardware failure, software corruption or overburdened network nodes. Often more than one of these factors is involved.
