Tag: Data Networks

A Data Network is a system designed to facilitate the transfer of data between individuals as well as organisations. It enables such modern marvels as the Internet and telecommunication. The points between which data is exchanged are called network access points or nodes.
—Sterlite Technologies limited, “Data Networks: The Unsung Hero of Organisational Success”

Data Network – The primary purpose of data transmission and networking is to facilitate communication and sharing of information between individuals and organizations. The two predominant types of data networks are broadcast networks, in which one node transmits information to several nodes simultaneously, and point-to-point networks, in which each sender communicates with one receiver.

Signals are typically transmitted via three main methodologies:

  1. Circuit Switching: Before two nodes communicate, they establish a dedicated communications channel through the network.
  2. Message Switching: Each message is routed in its entirety from switch to switch; at each switch, the message is stored and the information is read before being transmitted to the next switch.
  3. Packet Switching: Messages are broken down and information is grouped into packets; each packet is transmitted over a digital network via the most optimum route to ensure minimal lag in data network speed, then the message is reassembled at the destinations.

In order to establish communication across machines, datacenter networks depend on Transmission Control Protocol (TCP) and the Internet Protocol (IP), the Internet Protocol Suite that dictates exactly how data should be packetized, addressed, transmitted, routed, and received.
