The Effectiveness of Data Communication depends upon four characteristics.
1. Delivery - The message should be received by the correct device. Actually, the sender sends the message with an address, and the transmission medium sends the message to the correct address.
2. Accuracy - The message in the transmission medium should not get corrupted or modified into some other meaning. The original message should be delivered to the receiver.
3. Timeliness - The message should be delivered on time. the sender sends the message and waits for an acknowledgment from the receiver. If the message does not send to its correct destination on time then the sender again retransmits the message.
4. Jitter - Uneven Delay of packets is known as Jitter. If you are watching a video on YouTube, and Jitter occurs, which means an uneven delay of packets from sender to receiver occurs, then your video will be stuck in a buffering phase.
