Characteristics Of Data Communication  system

Data communication is the exchange of data between two devices by using transmission medium (Wire or Wireless). The effectiveness of a data communications system depends on some fundamental factors:

  • delivery 
  • accuracy
  • Timeliness
  • Jitter
  • Error detection & Correction



Delivery:

System must deliver the data to the correct destination. (MAC address, IP Address)

Accuracy:

The system must deliver the data accurately.  Altered data is unusable.

Timeliness:

In the case of video and audio, late delivery is useless. Communication system must deliver data in a timely manner. Timely means delivering data without any delay (real-time transmission).



Jitter:

Variation in the packet arrival time. It is the delay in the delivery of audio or video data packets. an uneven quality in the video is the result.

Error Detection & Correction:

  • Parity check
  • Checksum
  • CRC
