Jitter, often referred to as “unreliable latency”, is a phenomenon in networking and telecommunications where the timing or latency of data packets varies unpredictably. It can result in irregular delays in the delivery of data, causing disruptions in real-time communication and data transmission. Jitter can be caused by network congestion, packet loss, or variations in the network’s performance. Managing jitter is crucial for ensuring smooth and consistent data transmission, particularly in applications like VoIP (Voice over Internet Protocol) and video conferencing, where timing precision is essential for maintaining quality and reliability.
